Web29 feb. 2024 · This process involves the introduction of both carbon and nitrogen into the surface layers of the steel. Steel to be cyanided is normally heated in a molten bath of cyanide-carbonate-chloride salts (normally containing 30 % to 95 % of sodium cyanide) and then quenched in brine, water, or mineral oil. WebHeat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve the desired result such as hardening or softening of a material. Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, carburizing, normalizing and quenching.
