13-8 PH Stainless Steel
UNS S13800 | ASTM A564 | AMS 562913-8 PH Stainless Steel
13-8 (also known as 13-8Mo or by the trade name “XM-13”), is an age-hardening martensitic stainless steel with approximately 13% Chromium. 13-8 is typically processed with a two-step refining method. The fist melt is VIM (Vacuum Induction Melted), and this is followed by either VAR (Vacuum Arc Remelting) or ESR (Electroslag Remelt). This refining process, like 15-5 ensures 13-8 is capable of sustaining good transverse properties. 13-8 can be heat treated to achieve high strengths and hardness while maintaining good corrosion resistance.
Common industry/applications are: Aerospace, Food Processing, Chemical processing, Oil and Gas, Pumps and Valves, and Fasteners.
Product forms include round bar, plate & strip, and forgings.
