Patenting
Materials science; Metallurgy
The special heat treatment given to medium carbon,high carbon and low alloy steels wire rod is called patenting.The process consists of heating the material well above the ...
Carburizing
Materials science; Metallurgy
This is the most widely used process for surface hardening of steels.It is carried out on low carbon steel which contain from 0.01 to 0.25 percent carbon and known as carburizing ...
Martempering
Materials science; Metallurgy
Martempering involve heating the steal to the austenitizing temperature, followed by quenching in a constant temperature bath maintained above Ms point and the usual temperature ...
Process Annealing
Materials science; Metallurgy
In this treatment,steel is heated to a temperature below the lower critical temperature,and is held at this temperature for sufficient time and then cooled.
Spheroidizing
Materials science; Metallurgy
Spheroidizing is a heat treatment process which results in a structure consisting of globules or spheroids of carbide in matrix of ferrite.
Normalizing
Materials science; Metallurgy
Normalizing is a process of heating steel to about 40 to 50 degree above upper critical temperature,holding for proper time,and then cooling in still air or at room temperature.
Hardening
Materials science; Metallurgy
Hardening treatment consists of heating to hardening temperature,holding at that temperature followed by rapid cooling such as quenching in water,oil or salt baths.
