• Molten Salts

Distortion can produce out of tolerance part dimensions, stresses leading to cracking and premature failure. When quenching or tempering your parts, molten salt is the proven quench media to use in controlling distortion. DuBois has over 100 years of experience in the molten salt technology; providing products with wide operating temperature ranges and consistent performance. Our salts are offered in granular or briquette form, with or without anti-caking agent and dyed for identification purposes.
