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

Material supplied by the Company may vary significantly from this data, but will conform to all relevant and applicable standards. The PH alloy is generally better-suited for plate applications than are the semi austenitic alloys.

Upon cooling to room temperature, they undergo a transformation that changes the austenite to martensite. As this treatment is carried out at a low temperature, no distortion occurs and there is only specificatioon discolouration.

It is a through-hardening alloy, which allows it psecification be used in parts with large cross sections, where yield strengths in excess of ksi. The alloy can be cold formed in the annealed condition, utilizing conventional cold forming techniques. Austenitic Alloys Austenitic precipitation hardening steels retain their austenitic structure after annealing and hardening by ageing.


Hardening is achieved through the addition of one or more of the elements Copper, Aluminium, Titanium, Niobium, and Molybdenum. 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.

Stainless Steel – Precipitation Hardening – AMS

Copyright Wilsons Ltd. Also known as ” solution treating. Austenitic alloys remain nonmagnetic. If forming is required, do so in the overaged condition for best results. This shrinking is approximately 0. Strength Yield strengths for precipitation-hardening stainless steels are to MPa.

No liability will be specificatipn by the Company in respect of any action taken by any third party in reliance thereon. Material should be annealed after hot working for best heat treat response.

This alloy works well in all common hot working procedures. Physical properties Melting Range: This improved toughness is achieved by reduced delta ferrite content and control of inclusion size and shape. Tensile strengths range from to MPa.

Characterisation Precipitation hardening steels are characterised into one of three groups based on their specififation microstructures after heat treatment. No guarantee is given that the amd is from the latest issue of those sources or about the accuracy of those sources. In particular, mechanical property requirements vary widely with temper, product and product dimensions. Heat treatment is usually performed in air. Good transverse toughness properties are achieved by tight chemical composition control to prevent the formation of delta phaselow carbon content to minimize grain boundary precipitationand double vacuum melting to reduce alloy segregation.


Distributors will specificayion 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.

Registered in England No. Helium is the preferred shielding gas. Resistance methods or shielded fusion is recommended. This alloy is capable of being only mildly formed. During the hardening process a slight decrease in size takes place. After machining or another fabrication method, a single, low temperature heat treatment can be applied to increase the strength of the steel. This is a martensitic, precipitation hardening, chromium-nickel-copper stainless steel.

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. Aircraft components, fabricated parts in high pressure corrosive environments including valves, shafts, fasteners, fittings and gears.
