15-5 PH TY 1 STAINLESS PLATE

  • [print version]

  • Description

    15-5 PH is a martensitic, precipitation hardening, chromium-nickel-copper stainless steel. The Stainless Steel 15-5 PH alloy combines good strength, transverse toughness and ductility, hardness capability and corrosion resistance compared to 304 stainless. 15-5 PH may be used in the solution treated condition or heat treated to obtain a wide variety of properties. The 15-5 PH stainless was designed to have greater toughness than 17-4 PH. The 15-5 PH alloy is martensitic in structure in the annealed condition and is further strengthened by a relatively low temperature heat treatment which precipitates a copper-containing phase in the alloy.
