Specificatiom 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. Strength Yield strengths for precipitation-hardening stainless steels are to MPa. Material supplied by the Company may vary significantly from this data, but will conform to all relevant and applicable standards.

They have a better combination of strength and corrosion resistance than when a,s with the heat treatable series martensitic alloys. This is a martensitic, precipitation hardening, chromium-nickel-copper stainless steel.

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.

Mechanical Property Value Spec: This alloy works well in all common hot working procedures. Also known as ” solution treating. This is known as ageing or age-hardening. AMS Carbon C 0. Registered in England No. Semi-austenitic Alloys Unlike martensitic precipitation hardening steels, annealed semi-austenitic precipitation hardening steels are soft enough to be cold worked.

As this treatment is carried out at a low temperature, no distortion occurs and there is only superficial discolouration. Spedification the hardening process a slight decrease in size takes place. Characterisation S;ecification hardening steels are characterised into one of three groups based on their final microstructures after heat treatment.

Reducing atmospheres should not be used because of the potential for nitrogen contamination. Both alloys exhibit high strength and moderate corrosion resistance. Inclusion control is done by consumable electrode remelting specificaiton the electro-slag remelting ESR process. Aging is normally carried out from to 1,F to Cdepending upon the desired final properties. Modulus of Elasticity Tension. This Data is indicative only and as such is not to be relied upon in place of the full specification.

We recommend using the latest version if you don’t already have it.

Disclaimer Conditions of Sale Conditions of Purchase. A wide range of properties can be produced by this one step heat treatment.

The alloy combines good strength, transverse toughness and ductility, hardness capability and corrosion resistance compared with stainless. This improved toughness is achieved by reduced delta ferrite content and control of inclusion size and shape. 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.

This shrinking is approximately 0.

Certain files on this page will require the Adobe Reader software. All information is based on our present knowledge and is given in good faith. Precipitation hardening stainless steels are chromium and nickel containing steels that provide an optimum combination of the properties of martensitic and austenitic grades.

Cold work is restricted only by this alloys high initial yield strength. After forging, parts should be cooled to room temperature, then solution treated prior to aging. The PH alloy is generally better-suited for plate applications than are the semi austenitic alloys. If forming is required, do so in the overaged condition for best results. 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.

The three types are: 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.

The most specufication known precipitation hardening steel is PH. These include plasma arc, electron beam, gas metal arc, and shielded metal arc processes. As it is carried out at low temperature, the component undergoes no distortion.

Corrosion resistance is similar to that found in grade stainless steel. Aircraft components, fabricated parts in high pressure corrosive environments including valves, shafts, fasteners, fittings and gears. Helium is the preferred shielding gas. Copyright Wilsons Ltd.
