Hardening is achieved through the addition of one or more of the elements Copper, Aluminium, Titanium, Niobium, and Molybdenum. Also known as ” solution treating.

The PH stainless steel alloy is martensitic in structure in the annealed condition and is further strengthened by a low temperature treatment which precipitates a copper containing phase in the alloy.

This increases the hardness and strength of the material. This is a martensitic, precipitation hardening, chromium-nickel-copper stainless steel. This is known as ageing or age-hardening. Mechanical Property Value Spec: Cold work is restricted only by this alloys high initial yield strength.

15-5PH Stainless Steel (AMS 5659/ AMS 5862)

After forging, parts should be cooled to room temperature, then solution treated prior to aging. 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.

This Data is indicative only and as such is not to be relied upon in place of the full specification. Austenitic alloys remain nonmagnetic. The PH alloy is generally better-suited for plate applications than are the semi austenitic alloys.

The alloy combines good strength, transverse toughness and ductility, hardness capability and corrosion resistance compared with stainless. Precipitation hardening stainless steels are chromium and nickel containing specificstion that provide an optimum combination of the properties of martensitic and austenitic grades.

Physical properties Melting Range: 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, Forging Products, Wire Products, Tubular Products, and Casting Products. During the hardening process a slight decrease in size takes place.

Precipitation hardening steels can be readily welded using procedures similar to those used for the series of stainless ama.

This alloy is produced by a primary vacuum induction melt process VIMfollowed by a consumable vacuum arc remelting VAR step. Strength Yield strengths for precipitation-hardening stainless steels are to MPa.

All information is based on our present knowledge and is given in good faith. This alloy is capable of being only mildly formed. No liability will be accepted by the Company in respect of any action taken by any third party in reliance thereon.

The composition and processing of PH alloy is carefully controlled to minimize its content of delta ferrite, which is present in the PH stainless steel material. We recommend using the latest version if you don’t already have it.

Characterisation Precipitation hardening steels are characterised into one of three groups based on their final microstructures after heat treatment.

This alloy works well in all common hot working specificxtion. 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.

Heat treatment is usually performed in air. Resistance methods or shielded fusion is recommended. The alloy can be cold formed in the annealed condition, utilizing conventional cold specificafion techniques.

Inclusion control is done by consumable electrode remelting using the electro-slag remelting ESR process. Heat treatment sprcification brazed components maybe done in inert atmospheres. The alloy is not favored for cold working but can be moderately formed. Upon cooling to room temperature, they undergo a transformation that changes the austenite to martensite.

For optimum properties, forging temperature should not exceed 1,F 1,C. This shrinking is approximately 0.
