Stainless Steel 15-5 PH

EOS StainlessSteel PH1 is a pre-alloyed stainless steel in fine powder form. The chemistry of EOS StainlessSteel PH1 conforms to the compositions of DIN 1.4540 and UNS S15500.

This kind of steel is characterized by having good corrosion resistance and excellent mechanical properties, especially in the precipitation hardened state. This type of steel is widely used in variety of medical, aerospace and other engineering applications requiring high hardness, strength and corrosion resistance.

This material is ideal for many  applications such as functional metal prototypes, small series products, individualized products or spare parts. Standard processing parameters use full melting of the entire geometry with 40µm layer thickness. Using standard parameters the mechanical properties are fairly uniform in all directions. Parts made from EOS StainlessSteel PH1 can be machined, spark-eroded, welded, micro shot-peened, polished and coated if required. Unexposed powder can be reused. Strength can be further increased by a single low temperature heat treatment. Compared to 17-4, it offers better transverse toughness and ductility.

15-5 Ph has high strength, hardness, and corrosion resistance and high strength at temperatures up to 315°C. This steel has a wide application, which includes valve parts, fittings and fasteners, shafts, gears, chemical process equipment, paper mill equipment, aircraft components and
other industrial components.

Typical applications:

  • Widely used throughout multiple industries including aerospace, petrochemical and food processing.
  • Any application where high strength and or corrosion resistance is required
