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.

  1. The specified material properties were determined at room temperature. They are multidimensionally dependent on many different machine and process parameters. Without further investigation, the material properties do not constitute a sufficient basis for component dimensioning.
  2. Specific heat treatment processes lead to optimized mechanical-technological properties to meet the component requirements.
