Type AISI 440A is a straight chromium martensitic stainless steel which combines the superior wear resistance of high
carbon alloys with the excellent corrosion resistance of chromium stainless steels. It is magnetic in both the annealed and
hardened conditions. Maximum corrosion resistance is attained only in the fully hardened condition.
