It is a through-hardening alloy, which allows it to be used in parts with large cross sections, where yield strengths in excess of ksi. Austenitic alloys remain nonmagnetic. This alloy may be machined in any of the attainable conditions, however machining in HM will yield best tool life. After forging, parts should be cooled to room temperature, then solution treated prior to aging.

The PH alloy was designed to have greater toughness than PH, especially in the through-thickness short transverse direction.

This improved toughness is achieved by reduced delta ferrite content and control of inclusion size and shape. The alloy is not favored for cold working but can be moderately formed. 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.

Typical uses are aircraft apecification, 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. Heat treatment of brazed components maybe done in inert atmospheres. A wide range of properties can be produced by this one step heat treatment. Hardness remains lower than that for martensitic or semi-austenitic precipitation hardening steels.

Registered in England No. Copyright Wilsons Ltd. This alloy works well in all common hot working procedures. This is known as ageing or age-hardening.

Cold work is restricted only by this alloys high initial yield strength. This alloy is capable of being only mildly formed.

No guarantee is given that the information is from the latest issue of those sources or about the accuracy of those specitication. Due to the high strength of precipitation hardening stainless steels, most applications are in aerospace and other high-technology industries.

No liability will be accepted by the Company in specificatioh of any action taken by any third party in reliance thereon. Aircraft components, fabricated parts in high pressure corrosive environments including valves, shafts, fasteners, fittings and gears. Please note that the ‘Datasheet Update’ date shown above is no guarantee of accuracy or whether the datasheet is up to date.

The high tensile strengths speccification precipitation hardening stainless steels come after a heat treatment process that leads to precipitation hardening of a martensitic or austenitic matrix. Also known as ” solution treating.

Upon cooling to room temperature, they undergo a transformation that changes the austenite to martensite. All information is based on our present knowledge and is given in good faith. This increases the hardness and strength of the material. We recommend using the latest version if you don’t already have it.

This is a martensitic, precipitation hardening, chromium-nickel-copper stainless steel. Strength Yield strengths for precipitation-hardening stainless steels are to MPa.

Tensile strengths range specifciation to MPa.

The three types are: If forming is required, do so in the overaged condition for best results. Aging is normally carried out from to 1,F to Cdepending upon the desired final properties.

In the annealed condition, use machine speeds 20 to 30 percent lower than those used on stainless steel. Disclaimer Conditions of Sale Conditions of Purchase.
