How To Select A Stainless Steel Grade

Stainless steels are engineering materials with good corrosion-resistance, strength and fabrication characteristics.. Selecting the proper stainless steel grades involves weighing four qualities in the following order of importance:

1,Fabrication Operationsand how the product will be made (e.g., forging, machining, forming, welding, stamping, roll forming, four-slide operations).

2,Total Cost,includingmaterial and production costs and considering the cumulative savings of a maintenance-free product with longevity.

3,Corrosion or Heat Resistance,the primary reason for specifying stainless. The specific needs to know the nature of the environment and the degree of corrosion

4,Mechanical Properties,particularly strength at room, elevated or low temperature. The combination of corrosion resistance and strength is the basis for selection.

5,The corrosion, heat resistance and mechanical properties are all affected by the chemical composition of the stainless steel.

Stainless Steel Grade Comparison

For a comparison of chemical and mechanical properties of  stainless steel according to ASTM A240 SS

410 is a martensitic stainless steel that is air or oil hardened and responds well to

hardening and tempering operations. Considered a 12% chromium steel, it offers superb

201 STAINLESS STEEL

Type 201 stainless steel (UNS S 20100) is a low nickel, high-work hardening, austenitic chromium-nickel-manganese stainless steel that was developed to conserve nickel.

301 STAINLESS STEEL

Type 301 stainless steel (UNS S 30100) is an austenitic chromium-nickel stainless steel that can attain high tensile strength and ductility by cold-working.

304 STAINLESS STEEL

Type 304 stainless steel (UNS S 30400) is the most common austenitic chromium-nickel stainless steel. It can be used in a multitude of applications.

305 STAINLESS STEEL

Type 305 (UNS S30500) is an austenitic chromium-nickel stainless steel that has excellent corrosion resistance due to a higher nickel content

316/316L STAINLESS STEEL

Type 316L (UNS S31603) stainless steel has an extra-low carbon content and is a variation of Type 316

321 STAINLESS STEEL

Type 321 (UNS S32100) is an austenitic stainless steel that has fives times more titanium than carbon in its content.
