Cyanide Bath For Tool SteelsCategory: HEAT TREATMENT OF STEEL All high-carbon tool steels are heated in a cyanide bath. With this bath, the heat can be controlled within 3 deg. The steel is evenly heated without exposure to the air, resulting in work which is not warped and on which there is no scale. The cyanide bath is, of course, not available for high-speed steel because of the very high temperatures necessary. Next: Drop Forging Dies Previous: Carburizing Low-carbon Sleeves
