ASTM A564
Martensitic Stainless Steel 15-5PH

Material Characteristics

15-5PH is a stainless, martensitic, and hardenable Cr-Ni-Cu Steel with high strength and ductility as well as good weldability and forgeability. Typical fields of application are in medical, automotive, and aerospace areas. Through solution annealing and subsequent ageing, an increase in strength occurs. 15-5PH is applicable in a temperature range from - 200 °C to 300 °C.
