Stainless 309 is an austenitic chromium nickel stainless steel and offers a better corrosion resistance than the type 304 because of higher percentages of nickel and chromium. Suitable for parts requiring both corrosion and heat resistance and oxidation resistance up to 2000 °F. Strength at elevated temperatures is similar to that of 18-8 Stainless Steels. This alloy posses excellent resistance to oxidation as well as high tensile and creep strengths at elevated temperatures. It is generally considered as a heat-resisting alloy.
Stainless steel 410 is a basic martensitic grade which contains 11.5% chromium, offering both exceptional wear and corrosion resistance. 410 is generally used for applications which involve mild corrosion, high strength, and heat resistance.
Of the 400 series of stainless steels, 400C has the highest carbon content and moderate corrosion resistance and can heat-treat to the highest harness of RC 60. (In contrast, 416 is normally heat treated to RC 26/32)
Stainless 422 is a hardenable, martensitic stainless steel with better strength at higher temperatures as high as 1200 F. It is capable of being heat treated to various high strength levels.
