Molten salts are usually used as a medium in Carburizing, Hardening, Annealing, Preheating, Tempering, Martempering, Austempering etc. Molten salt baths of various composition are available to cover the temperature range 150-1350`c. Since the work is surrounded by salt, heating is uniform, distortion is less and part can be machined before heat treatment. Treated parts have a clean, bright, scale free finish and decarburization can be completely eliminated.
