Reducing atmospheres should not be used because of the potential for nitrogen contamination. AMS Carbon C 0. During the hardening process a slight decrease in size takes place. This alloy is produced by a primary vacuum induction melt process VIMfollowed by a consumable vacuum arc remelting VAR step.

Heat treatment of brazed components maybe done in amz atmospheres.

Helium is the preferred shielding gas. Both alloys exhibit high strength and moderate corrosion resistance. The high tensile strengths of precipitation hardening stainless steels come after a heat treatment process that specificwtion to precipitation hardening of a martensitic or specificaion matrix. Aging is normally carried out from to 1,F to Cdepending upon the desired final properties.

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

It remains in solution during rapid cooling. Heat treatment is usually performed in air.

After machining or another soecification method, a single, low temperature heat treatment can be applied to increase the strength of the steel. These include plasma arc, electron beam, gas metal arc, and shielded metal arc processes. Hardening is achieved through the addition of one or more of the elements Copper, Aluminium, Titanium, Niobium, and Molybdenum.

Registered in England No. Copyright Wilsons Ltd. This alloy may be machined in any of the attainable conditions, specificaton machining in HM will yield best tool life. Typical mechanical properties achieved for PH after solution treating and age hardening are given in the table on the attached page.

Corrosion resistance is similar to that found in grade stainless steel. The alloy can be cold formed in the annealed condition, utilizing conventional cold forming techniques. The PH alloy was designed to have greater toughness than PH, especially in the through-thickness short transverse direction. 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 specigication phaselow carbon content to minimize grain boundary precipitationand double vacuum melting to reduce alloy segregation.

No guarantee is given that the information is from the latest issue of those sources or about the accuracy of those sources. Also known as ” solution treating. For optimum properties, forging temperature should not exceed 1,F 1,C.

Precipitation hardening stainless steels have moderate to good speccification resistance in a range of environments. 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. As this treatment is carried out at a low temperature, no distortion occurs and there is only superficial discolouration.

After forging, parts should be cooled to room temperature, then solution treated prior to aging. The alloy is not favored for cold working but can be moderately formed. Strength Yield strengths for precipitation-hardening specifiication steels are to MPa. Aircraft components, fabricated parts in high pressure corrosive environments including valves, shafts, fasteners, fittings and gears.
