Both alloys exhibit high strength and moderate corrosion resistance. Physical properties Melting Range: Aging is normally carried out from to 1,F to Cdepending upon the desired final properties. Distributors will offer small quantity specificatoin 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.

This Data is indicative only and as such is not to be relied upon in place of the full specification.

Austenitic Alloys Austenitic precipitation hardening steels retain their austenitic structure after annealing and hardening by ageing. Inclusion control is done specifidation consumable electrode remelting using the electro-slag remelting ESR process. This shrinking is approximately 0. A wide range of properties can be produced by this one step heat treatment. 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.


After machining or another fabrication method, a single, low temperature heat treatment can be applied to increase the strength of the steel. Heat to F C for 4 hours, air cool.

Modulus of Elasticity Tension. This is a martensitic, precipitation hardening, chromium-nickel-copper stainless steel.

During the hardening process a slight decrease in size takes place. Corrosion resistance is similar to that found in grade stainless steel. For optimum properties, forging temperature should not exceed 1,F 1,C.

The PH alloy is generally better-suited for plate applications than are the semi austenitic alloys.

specifixation Material supplied by the Company may vary significantly from this data, but will conform to all relevant and applicable standards.

Heat treatment of brazed components maybe done in inert atmospheres.

As this treatment is carried out at a low temperature, no distortion occurs and there is only superficial discolouration. They have a better combination of strength and corrosion resistance than when compared with the heat treatable series martensitic alloys.

This alloy is capable of being only mildly formed. Hardness remains lower than that for martensitic apecification semi-austenitic precipitation hardening steels. Precipitation hardening stainless steels are chromium and nickel containing steels that provide an optimum combination of the properties of martensitic and austenitic grades.


All information is based on our present knowledge and is given in good faith. This increases the hardness and strength of the material.

This alloy works well in all common hot working procedures. Also known qms ” solution treating. The PH alloy was designed to have greater toughness than PH, especially in the through-thickness short transverse direction.

The latter precipitation hardening alloys generally require more steps to complete heat treatment. No guarantee is given that the information is from the latest issue of those sources or about the accuracy of those sources. The three types are: This alloy may be machined in any of the attainable conditions, however machining in HM will yield best tool life. Austenitic alloys remain nonmagnetic.

Helium is the preferred shielding gas. Due to the high strength of precipitation hardening stainless steels, most applications are in aerospace and other high-technology industries. Air cool or oil quench to below 60F 15C to ensure complete transformation to martensite.
