Quenchants

UCON™ quenchants are a series of nonflammable, aqueous solutions containing special polymers and corrosion inhibitors for quenching ferrous and nonferrous metals. They can replace water, oil, or brine solutions and are the preferred quenching media for both low- and high-hardenability, plain carbon, and alloy steels. UCON™ quenchants provide much wider flexibility in quench severity than water or oil, reducing cracking, distortion, and residual stress in quenched parts. Use of UCON™ quenchants is permitted by most major industrial and military specifications. UCON™ Quenchant A is classified as a Type I Quenchant (AMS 3025B) for aluminum heat treating in the aerospace industry. UCON™ quenchants have been tested to the Standard 6930 Flammability Classification of Industrial Fluids and carry the distinction as an “FM Approved” product.

In the U.S. UCON™ quenchants are sold solely by Tenaxol, Inc.
