These bars are made from a blend of iron, high chromium, nickel, molybdenum, and copper, which gives them an edge in corrosion resistance compared to regular stainless steels. The elevated levels of nickel and molybdenum offer fantastic protection against pitting, crevice corrosion, and stress corrosion cracking, while the copper boosts their performance in environments with sulfuric and phosphoric acids. With excellent tensile strength, toughness, weldability, and dimensional stability, these bars deliver robust performance even in the harshest conditions.
