Product Description

Corrosion Resistance SUS431 DIN 1.4057 X17crni16-2 AISI 431 Stainless Steel Round Bar

1: 431 steel introduction
Grade 431 stainless steels is a nickel-containing martensitic stainless steel, which has better corrosion resistance and mechanical properties than straight chromium stainless steel.
The higher carbon content makes it tend to form chromium carbide, and therefore the formation of chromium-depleted areas make 1.4057 material susceptible to intergranular corrosion. However, the surface polishing can improve its corrosion resistance.
