Annealing,in general,involves heating to predetermined temperature,holding at this temperature,and finally cooling at a very slow rate.The temperature,to which steel is heated,and the holding time ...
Bronizing is one of the recent methods of surface hardening,which may be applied to any ferrous material but is generally adopted for carbon steel and tool steel.
This process is specifically used for improving wear resistance of mild,plain carbon or very low alloy steels.Carbonitriding is carried out at low temperatures in the range 800 to 870 degree in a gas ...
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 steels.
Chromizing is also used for surface hardening of both carbon and tool steels.The components to be chromized are packed with fine chromium powder and additives.
In this process,the parts to be heat treated are immersed in a liquid bath at 800 to 960 degree of NaCN with the concentration varying between 25 and 90 percent.
The process,also known as homogenizing annealing,is employed to remove any structural non uniformity.In diffusion annealing treatment,steel is heated sufficiently above the upper critical ...
