Description

 

Type 440A is a straight chromium martensitic stainless steel which combine 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.
