Nu-Sal

Description

‍

Nu-Sal is a barium free chloride mixture with low weight per cubic foot properties and has excellent fluidity within its working temperature range. It is easily washed from oil-quenched work because it is completely water soluble. Also, Nu-Sal is not hygroscopic, so it is less corrosive than other salts to the metal fixtures, electrodes, etc.

‍

Nu-Sal can be used for all neutral salt bath heating operations. These include austenitizing of carbon and low alloy steels for hardening, reheating carburized steels, annealing and spheroidizing. Nu-Sal is the ideal austenitizing medium for steels to be austempered, martempered, or otherwise isothermally quenched, because its fluidity minimizes drag-out and it dissolves readily in the salt bath quench. It can be used as a pre-heat for high-speed steel tools, replacing barium containing salts if it is desirable to use the preheat bath for austenitizing other types of steel.
