13-8 Supertough Stainless AMS5934
ATI 13-8 Supertough® Alloy (UNS S13800)
13-8 Supertough® Alloy is a modification of the standard ATI 13-8 alloy, and has superior fracture toughness and Charpy impact energies, even at cryogenic temperatures. These improvements have been achieved with tighter chemistry controls and thermo-mechanical processing practices. This improved alloy is a martensitic precipitation-hardening stainless steel that has excellent strength, high hardness, and good corrosion resistance.
