15-5 PH Stainless Steel (UNS N06002)
Altemp Alloys is a supplier of 15-5 PH stainless steel, a martensitic, precipitation hardening stainless steel. Good in corrosive, high-pressure environments, it is ideally suited for several industries, including aerospace, petrochemical, chemical and food processing. 15-5 PH stainless steel offers exceptional performance for applications such as gears, shafts, fittings, valves and fasteners. In addition to corrosion resistant properties, 15-5 PH stainless steel plates have good strength, transverse toughness and ductility in comparison to 304 stainless steel. 15-5 PH Stainless Steel from Altemp is specified to AMS 5862, 5659, H1025 & ASTM A-564
Altemp Alloys offers 15-5 PH UNS S15500 in:
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:
- Conditioning using austenite.
- Air cooling, which turns the austenite into martensite.
- 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.
