Application of 2205 Duplex Stainless Steel in Pharmaceutical and Biotechnology

2205 Duplex Stainless Steel Machining characteristics The machining of 2205 duplex stainless steel is similar to that of 316L, but there are still some differences. Cold forming operations must take into account the higher strength and higher work hardening properties of duplex stainless steels. Forming equipment may require higher load capacities, and in forming operations, 2205 stainless steel will exhibit higher resilience than standard austenitic stainless steels. The higher strength of 2205 duplex stainless steel makes it more difficult to machine than 316L. The welding of 2205 duplex stainless steel can use the welding method of 316L stainless steel. However, heat input and interpass temperature must be tightly controlled to maintain the desired austenite-ferrite phase ratio and avoid precipitation of detrimental intermetallic phases. A small amount of nitrogen in the welding gas helps avoid these problems. When performing welding procedure qualification for duplex stainless steels, the commonly used method is…

Effect of Aging Temperature and Time on the Structure and Precipitated Phase of TP304H Stainless Steel

TP304H stainless steel has high thermal strength and good oxidation resistance, widely used in the high temperature section of boiler superheaters and reheaters over 600℃, and the maximum operating temperature can reach to 760℃. The use of TP304H stainless steel, to a certain extent, solves the over-temperature tube burst caused by the large temperature difference of the furnace smoke, and significantly improves the safety of the boiler operation. However, TP304H stainless steel is prone to structural transformation during long-term high temperature operation, resulting in material aging. Therefore, studying the structure transformation of TP304H austenitic stainless steel and its influencing factors when operating under high temperature conditions is of great significance for rationally arranging the running time of the material, monitoring the damage degree of the pipeline online, and improving the material itself. For this reason, through the high temperature aging simulation test, the influence of aging temperature and time on…

Characteristics, Technical parameters and forging methods of stainless steel flat welding flanges

In the early stage of forging deformation of stainless steel flat welded flanges, because the porous preform is easy to deform, the deformation force is small, and the density increases rapidly. In the later stage of forging forming, due to the closure of most of the pores, the deformation resistance increases, and the deformation force required to eliminate the residual pores increases rapidly. The deformation resistance is closely related to the deformation temperature. A higher deformation temperature is conducive to compaction and reduces the deformation resistance. The higher deformation rate is also conducive to the compactness of stainless steel flat welded flanges. The forging process of stainless steel flat welded flanges has stricter equipment requirements than traditional die forging, and the displacement characteristics of the punch must match the deformation and compact characteristics of the preform. The contact time between the blank and the mold should be as short as…

Causes and solutions for lateral cracking of 304 stainless steel product sidewalls

304 stainless steel products often have various cracking phenomena during the deep drawing process. Among them, lateral or point cracks on the sidewall are common processing failure forms of 304 stainless steel products with relatively large deep drawing. Especially in recent years, the cost-reduction work of stainless steel products processing procedures has continued to advance. The number of drawing passes has been reduced from 5 times to 3 times commonly used at present, and the number of intermediate annealing has been changed to one annealing or no annealing after stamping. The formability of the material puts forward higher requirements. The lateral or point-like cracking defects on the sidewall of stainless steel products may be caused by material inclusions, delta ferrite and other material intergranular defects, or may be caused by factors such as the drawing process and drawing oil during the processing of stainless steel products. The lateral or point…

Factors Affecting the Accuracy and Reliability of the Analysis Results of the Carbon Sulfur Determination

At present, Carbon Sulfur Determination are generally used for the analysis of carbon and sulfur elements in metals. In the process of using analytical instruments of various manufacturers, there are often unsatisfactory repeatability or reproducibility. In this regard, the first thing to suspect is the failure of the instrument, but often after checking the hardware of the instrument, it is concluded that the instrument is working normally. In the following, for the analysis of the principle, operation and analysis process of the carbon and sulfur analyzer, several factors that affect the accuracy and reliability of the analysis results of the Carbon Sulfur Determination are summarized. The amount of cosolvent added Another factor that affects the stability of analytical results is the amount of co-solvent added, which is very prominent when analyzing low-level samples. For example, when analyzing samples with carbon and sulfur mass fractions less than 15 μg/g, 1.5 g…

The necessity of stainless steel pickling passivation

Austenitic stainless steel has good corrosion resistance and high temperature oxidation resistance properties, good low temperature performance and excellent mechanical and processing properties. Therefore, it is widely used in chemical, petroleum, power, nuclear engineering, aerospace, marine, pharmaceutical, light industry, textile and other sectors. Its main purpose is to prevent corrosion and rust. The corrosion resistance of stainless steel mainly depends on the surface passivation film. If the film is incomplete or defective, the stainless steel will still be corroded. In engineering, pickling and passivation treatment is usually carried out to make the corrosion resistance potential of stainless steel play a greater role. In the process of forming, assembling, welding, welding seam inspection (such as flaw detection, pressure test) and construction marking of stainless steel equipment and components, surface oil stains, rust, non-metallic dirt, low melting point metal contaminants, paint, and welding Slag and spatter, etc., these substances affect the surface…

Oxidation Resistance of Stainless Steels

Oxidation is the formation of oxide rich scale. The scale, once formed, slows down further oxidation, unless it is mechanically removed or cracked, which can happen if the steel deforms under load. In stainless steel, used at elevatedtemperatureup to 1100°C forheat resistingtypes, this is used to advantage, the scale formed being predominantly chromium rich. The reformed scale layer will prevent further oxidation, but the metal lost in the formation of oxide will reduce the effective strength of the steel section. Oxidation resistance depends mainly on temperature, gas composition and moisture level and steel grade mainly chromium level.Austeniticstainless steel are the best choice as they also have better elevated temperature strength than the ferritic family. The higher thermal expansion rates of the austenitics can result in problems such as distortion and may lead to scale loss (spalling) during thermal cycling. Conditions for stable oxide formationOxidation is dependent mainly on the oxygen…

Application of 2205 Duplex Stainless Steel in Pharmaceutical and Biotechnology

2205 Duplex Stainless Steel Machining characteristics The machining of 2205 duplex stainless steel is similar to that of 316L, but there are still some differences. Cold forming operations must take into account the higher strength and higher work hardening properties of duplex stainless steels. Forming equipment may require higher load capacities, and in forming operations, 2205 stainless steel will exhibit higher resilience than standard austenitic stainless steels. The higher strength of 2205 duplex stainless steel makes it more difficult to machine than 316L. The welding of 2205 duplex stainless steel can use the welding method of 316L stainless steel. However, heat input and interpass temperature must be tightly controlled to maintain the desired austenite-ferrite phase ratio and avoid precipitation of detrimental intermetallic phases. A small amount of nitrogen in the welding gas helps avoid these problems. When performing welding procedure qualification for duplex stainless steels, the commonly used method is…

Effect of Aging Temperature and Time on the Structure and Precipitated Phase of TP304H Stainless Steel

TP304H stainless steel has high thermal strength and good oxidation resistance, widely used in the high temperature section of boiler superheaters and reheaters over 600℃, and the maximum operating temperature can reach to 760℃. The use of TP304H stainless steel, to a certain extent, solves the over-temperature tube burst caused by the large temperature difference of the furnace smoke, and significantly improves the safety of the boiler operation. However, TP304H stainless steel is prone to structural transformation during long-term high temperature operation, resulting in material aging. Therefore, studying the structure transformation of TP304H austenitic stainless steel and its influencing factors when operating under high temperature conditions is of great significance for rationally arranging the running time of the material, monitoring the damage degree of the pipeline online, and improving the material itself. For this reason, through the high temperature aging simulation test, the influence of aging temperature and time on…

Characteristics, Technical parameters and forging methods of stainless steel flat welding flanges

In the early stage of forging deformation of stainless steel flat welded flanges, because the porous preform is easy to deform, the deformation force is small, and the density increases rapidly. In the later stage of forging forming, due to the closure of most of the pores, the deformation resistance increases, and the deformation force required to eliminate the residual pores increases rapidly. The deformation resistance is closely related to the deformation temperature. A higher deformation temperature is conducive to compaction and reduces the deformation resistance. The higher deformation rate is also conducive to the compactness of stainless steel flat welded flanges. The forging process of stainless steel flat welded flanges has stricter equipment requirements than traditional die forging, and the displacement characteristics of the punch must match the deformation and compact characteristics of the preform. The contact time between the blank and the mold should be as short as…

Causes and solutions for lateral cracking of 304 stainless steel product sidewalls

304 stainless steel products often have various cracking phenomena during the deep drawing process. Among them, lateral or point cracks on the sidewall are common processing failure forms of 304 stainless steel products with relatively large deep drawing. Especially in recent years, the cost-reduction work of stainless steel products processing procedures has continued to advance. The number of drawing passes has been reduced from 5 times to 3 times commonly used at present, and the number of intermediate annealing has been changed to one annealing or no annealing after stamping. The formability of the material puts forward higher requirements. The lateral or point-like cracking defects on the sidewall of stainless steel products may be caused by material inclusions, delta ferrite and other material intergranular defects, or may be caused by factors such as the drawing process and drawing oil during the processing of stainless steel products. The lateral or point…

Heat Exchanger Type Application Select

A heat exchanger is a device built for efficientheat transferfrom one medium to another. The media may be separated by a solid wall, so that they never mix, or they may be in direct contact.They are widely used in space heating, refrigeration, air conditioning, power plants,chemicalplants, petrochemical plants, petroleum refineries, and natural gas processing. One common example of a heat exchanger is the radiator in a car, in which the heat source, being a hot engine-cooling fluid, water, transfers heat to air flowing through the radiator (i.e. the heat transfer medium). In almost any chemical, electronic, or mechanical system, heat must be transferred from one place to another or from one fluid to another. Heat exchangers are used to transfer heat from onefluidto another. A basic understanding of themechanicalcomponents of a heat exchanger is important to understanding how they function and operate. Heat exchangeris a component that allows the transfer…

Straightness of Stainless Steel Pipe

Stainless steel pipe is curved in the length direction, and the degree of curve is called the degree of curvature (Straightness). The curvature specified in the standard is generally divided into the following two types: A. Local curvature: Use a one-meter straight ruler to lean on the maximum bend of the stainless steel pipe, and measure the chord height (mm), which is the value of the local curvature. The unit is mm/m, and the expression is 2.5mm/m. . This method is also suitable for tube end curvature. B. Total curvature of the total length: Use a thin rope to tighten from both ends of the pipe, measure the maximum chord height (mm) at the bend of the steel pipe, and then convert it into a percentage of the length (in meters), which is the length of the stainless steel pipe The full-length curvature of the direction. For example: the length…

Stainless Steel Pipe Ovality

In the cross section of the stainless steel pipe, there is a phenomenon that the outer diameters are not equal, that is, there are maximum and minimum outer diameters that are not necessarily perpendicular to each other. The difference between the Maximum outer diameter and the minimum outer diameter is the Ovality (or out-of-roundness). In order to control the ovality, some stainless steel pipe standards stipulate the allowable tolerance of ovality, which is generally specified as not exceeding 80% of the outer diameter tolerance (implemented after negotiation between the supplier and the buyer). The general requirement standard for stainless steel pipe is ASTM A999. The OD under tolerance on all sizes is -0.031”. The over tolerance increases with OD size but for the range of 1-1/2 to 4 NPS the plus tolerance is also 0.031”. An additional ovality tolerance allowance is permitted for thin wall thickness pipe which is defined…

Wall Thickness of Stainless Steel Pipe

The wall thickness of stainless steel pipe cannot be the same everywhere, and there are objectively unequal wall thicknesses in the cross section and longitudinal pipe body, that is, uneven wall thickness. In order to control this non-uniformity, some stainless steel pipe standards such ASTM A312, ASTM A999 stipulate the allowable index of uneven wall thickness, which is generally specified not to exceed 80% of the wall thickness tolerance (implemented after negotiation between the supplier and the buyer).

Length of Stainless Steel Pipe and Tube

Delivery length is also called the length required by the user or the length of the order. The standard has the following regulations on delivery length: A. Normal length / Random Length (also called non-fixed-length length): Any stainless steel tube whose length is within the length range specified by the standard and has no fixed length requirement is called normal length. For example, the structural stainless steel pipe standard stipulates: hot-rolled (extruded, expanded) steel pipe 3000mm ~ 12000mm; cold drawn (rolled) steel pipe 2000mm ~ 10500mm. B. Fixed Length: The fixed-length should be within the usual length range, which is a certain fixed-length dimension required in the contract. However, it is impossible to cut out the absolute fixed-length length in actual operation, so the standard stipulates the allowable positive deviation value for the fixed-length length. Take the structural stainless steel pipe standard as: The yield rate of production of fixed-length…
