The term annealing,until and unless specified,means full annealing.It consists of heating steel to austenitic region,followed by slow cooling.Steel is heated to about 30 to 50 degree above the upper ...
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.
In this process,hypoeutectoid steel is heated above the upper critical temperature and held for some time at this temperature.This is done in order to get a completely austenitic structure and to ...
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 of bath lies between ...
Nitriding is most effective for those alloy steels which contain stable nitride forming elements such as aluminum,chromium,molybdenum,vanadium and tungsten.Nitriding is carried out in a ferritic ...
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.
Partial annealing is also referred to as interstitial annealing or incomplete annealing.In this process,steel is heated between the lower critical temperature and the upper critical temperature.
