440 CEVM Stainless Steel

AISI type 440CEVM stainless steel balls afford the advantage of reduced impurities for extreme applications.  Nickel based super alloys for high temperature, stainless steels for nuclear and aerospace, Cobalt based allow for medical, high purity copper alloys and very clean magnetic alloys for high permeability a applications for 440C Vacuum Melt.

Material Analysis:
All sizes and grades of corrosion-resisting hardened stainless steel balls are made to ASTM 756. Passivation to ASTM A380 and AMS 2700 is available upon request.
