   AMS 5659 (UNS S15500)

PRECIPITATION HARDENING STAINLESS STEEL BAR

   PRODUCT OVERVIEW

AMS 5659 (UNS S15500) is a martensitic precipitation hardening stainless steel which contains 4% copper. All the same advantages of AMS 5643 are present as well as single low temperature treatment. AMS 5659 offers very good uniformity of properties with excellent traverse notch toughness and ductility. When compared with AMS 5643, the alloy displays superior forgeability and mechanical properties in large sections. Produced by the consumable electrode vacuum arc re-melted route, enhances the alloy’s toughness and ductility.

The alloy offers excellent weldability and is readily weldable by all commercial welding processes. Forming characteristics are also good.
