15-5 PH is a variant of the older 17-4 chromium-nickel-copper precipitation hardening stainless steel. Both alloys exhibit high strength and moderate corrosion resistance. High strength is maintained to approximately 600 degrees F. The 15-5 alloy was designed to have greater toughness than 17-4. This improved toughness is achieved by reduced delta ferrite content and control of inclusion size and shape.
15-5PH is a stainless steel offering high strength and hardness with excellent corrosion resistance. 15-5 PH can be age-hardened by a low temperature treatment.15-5 PH has been used for applications for requiring high strength and toughness, such as valve parts, fitting, and fasteners, gears, engine parts, paper mill equipment, and aircraft components.
Precipitation hardening stainless steels are chromium and nickel containing steels that provide an optimum combination of the properties of martensitic and austenitic grades. Like martensitic grades, they are known for their ability to gain high strength through heat treatment and they also have the corrosion resistance of austenitic stainless steel.
The high tensile strengths of precipitation hardening stainless steels come after a heat treatment process that leads to precipitation hardening of a martensitic or austenitic matrix. Hardening is achieved through the addition of one or more of the elements Copper, Aluminium, Titanium, Niobium, and Molybdenum.
The advantage of precipitation hardening steels is that they can be supplied in a “solution treated” condition, which is readily machinable. After machining or another fabrication method, a single, low temperature heat treatment can be applied to increase the strength of the steel. This is known as ageing or age-hardening. As it is carried out at low temperature, the component undergoes no distortion.
15-5 PH is also referred to as XM-12 in some specifications.
Strength of 15-5 PH :
Yield strengths for precipitation-hardening stainless steels are 515 to 1415 MPa. Tensile strengths range from 860 to 1520 Mpa. Elongations are 1 to 25%. Cold working before ageing can be used to facilitate even higher strengths.
