15-5PH Stainless Steel (AMS 5659/ AMS 5862)
For optimum properties, forging temperature should not exceed 1,F 1,C. The 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.
In particular, mechanical property requirements vary widely with temper, product and product dimensions. Austenitic Alloys Austenitic precipitation hardening steels retain their austenitic structure after annealing and hardening by ageing.
Reducing atmospheres should not be used because of the potential for nitrogen contamination. This is known as ageing or age-hardening.
This alloy may be machined in any of the attainable conditions, however machining in HM will yield best tool life. Modulus of Elasticity Tension. We recommend using the latest version if you don’t already have it.
PH Stainless Steel (AMS / AMS ) – Aircraft Materials
Helium is the preferred shielding gas. Air cool or oil quench to below 60F 15C to ensure complete transformation to martensite.
Mechanical Property Value Spec: Hardening is achieved through the addition of one or more of the elements Copper, Aluminium, Titanium, Niobium, and Molybdenum. Upon cooling to room temperature, they undergo a transformation that changes the austenite to martensite. The alloy combines good strength, transverse toughness and ductility, hardness capability and corrosion resistance compared with stainless.
Corrosion resistance is similar to that found spscification grade stainless steel. Since the rate of cooling from the solution temperature is not critical, large cross sections can be air-cooled. This increases the hardness and strength of the material. No guarantee is given that the information is from the latest issue of those sources or about the accuracy of those sources. Precipitation hardening stainless steels have moderate to good corrosion resistance in a range of environments.

Austenitic alloys remain nonmagnetic. As this treatment is carried out at a low temperature, no distortion occurs and there is only superficial discolouration. After forging, parts should be cooled to room temperature, then solution treated prior to aging. Semi-austenitc steels retain their austenitic structure at room temperature but will form martensite at very low temperatures. During the hardening process a slight decrease in size takes place.
No liability will be accepted by the Company in respect of any action taken by any third party in reliance thereon.
Physical properties Melting Range: Tensile strengths range from to MPa. Please note that the ‘Datasheet Update’ date specificafion above is no guarantee of accuracy or whether the datasheet is up to date.
Distributors will offer small quantity buys while mills will generally only sell large quantities, with delivery times anywhere from 10 to 50 weeks depending on size and form required This material is stocked primarily in Bar Products by 41 distributors but is also available to a lesser extent in Flat Rolled Products, Spscification Products, Wire Products, Tubular Products, and Casting Products.
This alloy works well in all common hot working procedures. Typical uses are aircraft parts, rocket engine mounts, nuclear reactor parts, landing gear components, high performance shafts, and petrochemical parts that require high strength combined with good resistance to stress corrosion.
A wide range of properties can be produced by this one step heat treatment.
This alloy is capable of being only mildly formed.
