Stainless Steel Stainless steel is the abbreviation for stainless acid resistant steel. Steel that resists weakly corrosive media (such as air, steam and water), or possesses stainless properties, is called stainless steel. Our main products are: austenitic stainless steel, such as 1Mn18Cr18N, 50Mn18Cr5, 304, etc.; martensitic stainless steel, such as 13Cr9Mo2Co1NiVNbNB and 1Cr12Ni2WMoVNb; precipitation hardened stainless steel, such as 05Cr17Ni4Cu4Nb and 04Cr15Ni7Cu2MoNbVN; duplex stainless steel, such as 022Cr25Ni6Mo2N; S series semi-martensitic precipitation hardened stainless steel, such as 0Cr14Ni7Mo (S 08); and ferritic stainless steel, such as 1Cr17. These products are commonly used in key components of aero engines, gas turbines, steam turbines, and in the petrochemical field.
