AISI TypeC 440 Vacuum Melt Stainless Steel
440C Vacuum Melt is processed by Vacuum Induction Melting (VIM) to reduce impurities for very demanding applications. Nickel based super alloys for high temperature, stainless steels for nuclear and aerospace, Cobalt based alloy for medical, high purity copper alloys and very clean magnetic alloys for high permeability are typical applications for 440C Vacuum Melt.
