AMS 5621 Stainless Steel UNS S42000 Steel Flat Bar
Describe
AMS 5621 is a martensitic stainless steel with 12% chromium, which gives the material good corrosion resistance. AMS 5621 can be heat treated for greater hardness. Its corrosion resistance is best when the metal is hardened and the surface ground or polished.
