Cyanide Bath For Tool Steels






Category: 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.
