What does 12% Cr in the pump material S-6 mean?
The impeller material is chromium-molybdenum steel, such as 1Cr13, 2Cr13, etc
Determine which part of the pump is involved, and consult the API610 material section to find the corresponding material.
The 12%Cr series refers to stainless steels produced in accordance with the American ASTM standards, grade 410, which is equivalent to China’s stainless steel 1Cr13 and S41000. ASTM 410 (1Cr13) belongs to the category of martensitic stainless steels; it has good hardenability, high hardness and toughness, as well as good corrosion resistance, heat strength, and cold formability. It also exhibits excellent shock absorption properties. High-temperature or low-temperature tempering is required, but tempering should be avoided between 370–560°C.
