Austenitic stainless steel: austenitic stainless steel having at room temperature. Cr steel containing about 18%, Ni 8% ~ 10%, while about 0.1% C, with a stable austenite. Austenitic chromium-nickel stainless steel including the famous steel and 18Cr-8Ni increase on this basis Cr, Ni content and adding Mo, Cu, Si, Nb, Ti and other elements developed series of high Cr-Ni steel. And non-magnetic austenitic stainless steel with high toughness and ductility, but lower strength, it is impossible to make it through the phase change hardening, can only be strengthened by cold working. Such as adding S, Ca, Se, Te and other elements, it has a good and easy machinability. Stainless Steel Polished


Ferritic stainless steels: in the case of using the state to ferrite-based stainless steel. Chromium content of 11% to 30%, with a body-centered cubic crystal structure. Such steel is generally not contain nickel, sometimes also contain small amounts of Mo, Ti, Nb wait elements such steel with large thermal conductivity, expansion coefficient, good oxidation resistance, excellent resistance to stress corrosion, are used for the manufacture Weathering , steam, water and oxidizing acid corrosion of parts. The existence of such steel plastic poor ductility and corrosion resistance after welding and other shortcomings significantly reduced, thus limiting its application. Cold Rolled Coils Price

Austenitic - ferritic duplex stainless steel: austenitic and ferritic stainless steel accounts for about half of each organization. In the case of containing a low C, Cr content 18% ~ 28%, Ni content of 3% to 10%. Some steel further contains Mo, Cu, Si, Nb, Ti, N and other alloying elements. Both austenitic class steel and ferritic stainless steel features, higher compared with ferrite, ductility, toughness, brittle at room temperature, resistance to intergranular corrosion and welding performance were significantly improved, while maintaining iron ferritic stainless steel 475 ℃ brittleness and high thermal conductivity, with superplastic characteristics. stainless steel sheet supplier
