Stainless Steel PH1 - hardenable stainless steel for engineering and medical applications

EOS StainlessSteel PH1 is a stainless steel. The chemical composition conforms to the com-positions of 15-5 PH, DIN 1.4540 and UNS S15500. This kind of steel is characterized by having excellent mechanical properties, especially in the precipitation hardened state. This type of steel is widely used in a variety of medical, aerospace and other engineering applications requiring high hardness and strength. This material is ideal for many part-building applications such as functional metal prototypes, small series products, individualised products or spare parts.

  • Very high strength
  • Easily hardenable up to approx. 45 HRC


  • Engineering applications including functional prototypes
  • Small series products
  • Individualised products or spare parts
  • Parts requiring particularly high strength and hardness
