13 Cr said containing 13% Cr martensitic stainless steel.Martensite stainless steel mainly for chromium content from 12% to 18% within the scope of the low carbon and high carbon steel.Widely application of martensitic stainless steel has the following three categories: 1. The low carbon steel and carbon in 13% Cr 2. High carbon steel of 18% Cr 3. Low-carbon nickel (about 2%) of 17% Cr steel
L80-13 cr is a kind of oil well pipe steel.It has good resistance to carbon dioxide corrosion resistance, good corrosion resistance to sea water into the ocean of common steel in oil and gas.
