Corrosion-resistant steels

Corrosion-resistant steels are characterized by an increased resistance to acids and corrosion. They are basically divided into the categories of austenitic, ferritic, and martensitic steel.
Martensitic corrosion-resistant steels offer high protection against corrosion in the hardened state, excellent wear resistance, and outstanding cutting edge retention.
Austenitic corrosion-resistant steels offer very good corrosion resistance and very good hot and cold formability. They are generally cryogenic steels.
Ferritic corrosion-resistant steels are generally low in nickel and exhibit a high resistance to chloride-induced stress corrosion cracking.
