Case Hardening Steel
What Types of Metals Can Be Case Hardened?
Case hardening is a material processing method that is used to increase the hardness of the outer surface of a metal. Case hardening results in a very thin layer of metal that is notably harder than the larger volume of metal underneath of the hardened layer. Case hardening almost always requires elevated temperatures to perform. Through heating, the hardening can be caused by altering the crystal structure of a metal or adding new elements to the composition of the exterior surface of a metal. Since hardening processes reduce formability and machinability, case hardening is typically done once most other fabrication processes have been completed.

Heat Treatment
Carburising, case hardening may be used on suitably graded steel specifications, surfaces must be free from dirt and grease, and of low sulphur content. Case hardening can be carried out in salt baths with selected content depending on the type of salt and the depth of penetration required. Other considerations during the heat treatment process include the type of furnace, quenching medium and work piece transfer facilities. Time, temperatures and salt selection will be advised by your heat treatment provider.
