PRECIPITATION HARDENING STAINLESS STEEL / APPLICATION
Primary structures are austenite or martensite, which possess high strength, corrosion resistance, oxidation resistance and superior hot working performance.
The alloy is usually produced by AOD / VOD /VIM followed by electroslag refining (ESR) / VAR if necessary for special purpose.
Bars and, where applicable, forgings are subjected to ultrasonic examination based on the different levels according to the buyers' requirements.
Bars are usually supplied black / bright in the annealed condition.
Final heat treatment - solution treatment.
Primary structures are austenite or martensite, which possess high strength, corrosion resistance, oxidation resistance and superior hot working performance.
The popular steel grades of Precipitation hardening-stainless steel are BS X5CrNiCuNb16-4, BS X7CrNiAl17-7, BS 1.4568, BS X5CrNiMoCuNb14-5,17-4PH, S17400, ASTM 630, SUS630, STS630, which are normally through precipitation hardening (also known as age-hardening) treatment practice.
Those materials are widely used in manufacturing the high strength, anti-corrosive forge piece for planes, gas turbine and other machined parts.

HEAT TREATMENT PRACTICE
Heat treatment is only suitable for specific grades of stainless steel. When heat treating a stainless the hardening temperatures, including rate of heating, cooling and soaking times will vary due to several factors such as the shape and size of each component. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Please consult with the heat treatment provider for whole guidance on heat treatment of stainless steel grades. We are delighted to help to work with you the special heat treatment based on your special requirements.
