Stainless Steel 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 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.

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.\

904L 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.

410 stainless steel is a hardenable martensitic stainless steel alloy. Unlike austenitic grades it can be heat treated ("quench and temper") to generate high strength with good ductility. 410 alloy is required when strength, hardness and wear resistance is required with some corrosion resistance.

Due to the hardening capabilities of this steel, other properties and the resulting performance of this material are somewhat compromised. The alloy can only effectively be used in mildly corrosive environments. The operating temperature range is limited a) a loss of strength by over tempering at elevated temperatures and b) a loss of ductility at sub-zero temperatures.
Type 410 is officially a stainless steel but characteristically the material is actually a compromise of high carbon steel alloy (which promotes wear resistance) with chromium stainless steel (which promotes corrosion resistance).

This steel is ideal for use in the manufacture of highly stressed parts found in a variety of industries including petrochemical, automotive and power generation.

Other Materials Testing:

• NACE MR0175, H2 Service, Oxygen Service, Cryo Service, etc.
• Background of 410 Stainless Steel Pipes and Tubes
• Grade 410 is the basic martensitic stainless steel; like most non-stainless steels it can be hardened by a "quench-and-temper" heat treatment. It contains a minimum of 11.5 per cent chromium, just sufficient to give corrosion resistance properties. It achieves maximum corrosion resistance when it has been hardened and tempered and then polished. Grade 410 is a general purpose grade often supplied in the hardened, but still machinable condition, for applications where high strength and moderate heat and corrosion resistance are required.
• Martensitic stainless steels are optimised for high hardness, and other properties are to some degree compromised. Fabrication must be by methods that allow for poor weldability and usually the need for a final heat treatment. Corrosion resistance of the martensitic grades is lower than that of the common austenitic grades, and their useful operating temperature range is limited by their loss of ductility at sub-zero temperatures and loss of strength by over-tempering at elevated temperatures.
• Composition of 410 Stainless Steel Pipes and Tubes
• Typical compositional ranges for grade 410 stainless steels are given in table 1.

Table 1. Composition ranges for 410 grade stainless steel

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

Both 347/347H are used primarily in elevated temperature applications.

Physical Properties of 347 Stainless Steel Pipes and Tubes The physical properties of Types 321 and 347 are quite similar and, for all practical purposes, may be considered to be the same. The values given in the table may be used to apply to both steels.
When properly annealed, the Alloys 321 and 347 stainless steels consist principally of austenite and carbides of titanium or columbium. Small amounts of ferrite may or may not be present in the microstructure. Small amounts of sigma phase may form during long time exposure in the 1000⁰F to 1500⁰F (593⁰C to 816⁰C) temperature range. The stabilized Alloys 321 and 347 stainless steels are not hardenable by heat treatment. The overall heat transfer coefficient of metals is determined by factors in addition to thermal conductivity of the metal. In most cases, film coefficients, scaling, and surface conditions are such that not more than 10 to 15% more surface area is required for stainless steels than for other metals having higher thermal conductivity. The ability of stainless steels to maintain clean surfaces often allows better heat transfer than other metals having higher thermal conductivity.
