Heat treating (or heat treatment) is a group of industrial and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical .
Post Weld Heat Treatment is a mandatory requirement for the fabrication and construction of pressure vessels. The residual stresses formed during welding can cause metal failures. The macro structure also changes during the welding process and makes the steel weak. PWHT removes these stresses and restores the macro structure of the steel.
In this article we will discuss about the heat treatment of spring steels. Any metal, or alloy which can be hard drawn, or rolled to fairly high strength and retains sufficient ductility to form, may be used for springs, or any alloy which can be heat treated to high strength and good ductility before, or .
