Chemical Composition

347 Stainless Steel is variant of the basic austenitic 18/8 Grade 304 with added Columbium - the introduction of Columbium stabilizes the steel and eliminates carbide precipitation which subsequently causes intergranular corrosion. The steel has excellent forming and welding qualities and excellent toughness even at cryogenic temperatures.

Benefits of 347 Stainless Steel:

• Higher creep stress and rupture properties when compared with 304
• Ideal for high temperature service
• Overcomes sensitization and intergranular corrosion concerns
• Can be used in elevated temperature applications for ASME Boiler and Pressure Vessel Code applications
• Due to stabilisation the material offers better overall corrosion resistance when compared to 304/304L
• Excellent mechanical properties
• A high carbon version (347H) is also available

Typical Uses:

• Heat exchangers
• High temperature steam service
• High temperature chemical process

Chemical Composition of 347 Stainless Steel Pipes and Tubes
Represented by ASTM A240 and ASME SA-240 specifications.

Type 321 is a standard austenitic 18/8 chromium nickel alloy with the addition of Titanium making it an excellent choice in elevated temperature environments. The titanium stabilises the material removing its susceptibility to the effects of intergranular corrosion. 321 is therefore the stainless steel material of choice for applications in working environments up to 9000 C. A drawback of Type 321 is that the titanium does not transfer well across a high temperature arc, so it is not recommended as a welding consumable. In such instances, 347 is the preferred choice as the Niobium performs the same function as Titanium but can be still transferred across a high temperature arc. Type 347 is therefore the consumable of choice for welding Grade 321. The steel has excellent forming and welding qualities and excellent toughness even at cryogenic temperatures. If you are looking for a stainless steel to provide resistance to intergranular corrosion, 304L is the normal choice as it is a more commonly used and supplied steel. However, 321 is a much better option in operating temperature environments in excess of 5000 C and therefore have its own merits. Note that Type 321 does not polish well so it is not practical to use this material as cosmetic architectural feature.

Background Grade 316 is the standard molybdenum-bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments.Grade 316L, the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). There is commonly no appreciable price difference between 316 and 316L stainless steel.The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures.

Type 202 Stainless Steel Is An Austenitic Chromium-nickel-manganese Stainless Steel Which Was Developed To Conserve Nickel. Type 202 Is A Lower Cost Alternative To Conventional Cr-ni Stainless Steels Such As 301 And 304. Nickel Is Replaced By Additions Of Manganese And Nitrogen. It Is Non-hardenable By Thermal Treatment, But May Be Cold Worked To High Tensile Strengths. Type 201 Is Essentially Nonmagnetic In The Annealed Condition And Becomes Magnetic When Cold Worked. Type 201 Can Be Substituted For Type 301 In Many Applications

Stainless Steel 202 Pipe Product Forms:

• Sheet, Strip

Stainless Steel 202 Pipe Typical Applications:

• Typical Applications For Types 202 Are Cookware, Hose Clamps, Piston Rings, Transit Car Structural Member, Transit Car Roofing/Siding, Thermal Window Spacers, Air Bag Containers, And Truck Trailer Posts And Door Frames.

Stainless Steel 202 Pipe Processing:

• The Annealing Temperature For Type 202 Is Between 1850-2000°F. Rapid Cooling Through The Carbide Precipitation Range (1500 – 800 ° F) Is Necessary To Keep The Carbides In Solution And Prevent Sensitization. Type 201 Is Not Hardenable By Thermal Treatment; It Is Only Hardenable By Cold Working.

Stainless Steel 202 Pipe Forming:

• Type 202 Has Similar Bending, Forming And Drawing Characteristics To Type 301 Stainless Steel

Stainless Steel 202 Pipe Welding:

• Type 202 Can Be Welded By All Conventional Methods Applied To 18 Percent Chromium, 8 Percent Nickel Steels. Filler Metal Of The Conventional Chromium-nickel Analyses Can Be Used. Like Other Austenitic Stainless Steels Where Carbon Is Not Controlled Below 0.03%, Type 202 Is Susceptible To Intergranular Corrosion In The Weld Heat Affected Zone.

Stainless Steel 202 Pipe Corrosion:

• Type 202 Is Resistant To A Wide Variety Of Mild To Moderately Corrosive Environments. It Has Corrosion Resistance Approaching That Of Types 301And Has Been Successfully Substituted For 304 In Many Mild Environments.

904L is a high-alloy austenitic stainless steel with low carbon content. The grade is intended for use under severe corrosive conditions. It has been application proved over many years and was originally developed to resist corrosion in dilute sulfuric acid. It is standardized and approved for pressure vessel use in several countries. Structurally, 904L is fully austenitic and is less sensitive to precipitation ferrite and sigma phases than conventional austenitic grades with high molybdenum content. Characteristically, due to the combination of relatively high contents of chromium, nickel, molybdenum and copper 904L has good resistance to general corrosion, particularly in sulfuric and phosphoric conditions.

Chemical Composition %
Typical Applications

• Production and transport of sulfuric acid
• Metal pickling in sulfuric acid
• Production and concentration of phosphoric acid
• Use in seawater, brackish water, condensers, heat exchangers and pipe work in general
• Paper and allied industries
• Gas washing
• Chemical and pharmaceutical industries

Tensile requirements

• Tensile Strength (KSI) 70
• Yield Strength (KSI) 25
• KSI can be converted to MPA (Megapascals) by multiplying by 6.895.
