Heat Treating

Process Name
Heat Treating
Chemical hazards in heat treating of steel include nitrogen dioxide for annealing in nitrate salt baths and oil mist for quenching in oils. Lead exposure can occur if lead quenching baths are used. In the case hardening processes the following potential chemical exposures exist: 1) gas carburizing and pack carburizing--carbon monoxide; 2) cyaniding and liquid carburizing--cyanide; 3) gas nitriding--ammonia; [Burgess, p. 205-14]
