During the hardening process a slight decrease in size takes place. This improved toughness is achieved by reduced delta ferrite content and control of inclusion size and shape. In particular, mechanical property requirements vary widely with temper, product and product dimensions.

Resistance methods or shielded fusion is recommended. Heat to F C for 4 hours, air cool. Heat treatment is usually performed in air. The PH alloy was designed to have greater toughness than PH, especially in the through-thickness short transverse direction.

Semi-austenitic Alloys Unlike martensitic precipitation hardening steels, annealed semi-austenitic precipitation hardening steels are soft enough to be cold worked. Corrosion resistance is similar to that found in grade stainless steel.

PH Stainless Steel (AMS / AMS ) – Aircraft Materials

Precipitation hardening stainless steels are chromium and nickel containing steels that provide an optimum combination of the properties of martensitic and austenitic grades.

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

Registered in England No. Specificstion PH alloy is generally better-suited for specifixation applications than are the semi austenitic alloys. Hardening is achieved through the addition of sprcification or more of the elements Copper, Aluminium, Titanium, Niobium, and Molybdenum. This increases the hardness and strength of the material. 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.

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.

Air cool or oil quench to below 60F 15C to ensure complete transformation to martensite. 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.

After forging, parts should be cooled to room temperature, then solution treated prior to aging. Due to the high strength of precipitation hardening stainless steels, most applications are in aerospace and other high-technology industries. No guarantee is given that the information speicfication from the latest issue of those sources or about the accuracy of those sources. 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.

Upon cooling to room temperature, they undergo a transformation that changes the austenite to martensite.

The alloy combines good strength, transverse toughness and ductility, hardness capability and corrosion resistance compared with stainless. It remains in solution during rapid cooling. It may be used in the solution specitication condition or heat treated to obtain a wide variety of properties. Hardness remains lower than that for martensitic or semi-austenitic precipitation hardening steels. Precipitation hardening steels can be readily welded using procedures similar to those used for the series of stainless steels.

Physical properties Melting Range: Precipitation hardening stainless steels have moderate to good corrosion resistance in a range of environments.

Please note that the ‘Datasheet Update’ date shown above is no guarantee of accuracy or whether the datasheet is up to date. After machining or another fabrication method, a single, low temperature heat treatment can be applied to increase the strength of the steel.

We recommend using the latest version if you don’t already have it. Disclaimer Conditions of Sale Conditions of Purchase. These include plasma arc, electron beam, gas metal arc, and shielded metal arc processes. 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. Since the rate of cooling from the solution temperature is not critical, secification cross sections can be air-cooled.

This is a martensitic, precipitation hardening, chromium-nickel-copper stainless steel.

Helium is the preferred shielding gas. They have a better combination of strength and corrosion resistance than when compared with the heat treatable series martensitic alloys. This is known as ageing or age-hardening.
