Stainless Steel 455/ Custom 455 (AMS 5617)
Technical Data Sheet
Alloy 455 is a martensitic age hardenable stainless steel, which has properties of high strength and good corrosion resistance. Alloy 455 is relatively soft and formable in the annealed condition, however through a single-stage aging treatment alloy 455 develops an exceptionally high yield strength with good ductility and toughness.
