15-5 PH Stainless Steel Composition

The composition of 15-5 PH stainless steel includes high levels of chromium, nickel and copper. Carbon, manganese, phosphorus, sulfur, silicon and columbium plus tantalum may also be present in trace amounts, with each not exceeding 1 percent of the compositional total.

Heat Treated 15-5 PH Stainless Steel

Heat treatments are used to strengthen 15-5 alloys. There are eight standard conditions for 15-5 stainless steel after treatment - H 900, H 925, H 1025, H 1075, H 1100, H 1150, H 1150+1150 and H 1150-M. Heat treating 15-5 PH follows the following steps:

  1. Conditioning using austenite.
  2. Air cooling, which turns the austenite into martensite.
  3. Precipitation hardening until the desired condition is reached.

15-5 PH can be further heat-treated when in precipitation-hardened condition to provide improved resistance to stress corrosion cracking for high temperature applications. Fabrication is recommended after the metal has been heat treated to minimize distortion and stress.

Altemp Alloys also stocks a number of other stainless steel alloys, including A-286 and 17-7 PH.
