Advanced Bio-stable Polymer Quenchant for Induction Hardening Applications




Aqua-Quench 145 is an advanced bio-stable polymer quenchant designed for introduction hardening and immersion quenching applications, and represents another breakthrough in technology from Houghton International.




Aqua-Quench 145 is a polymer quenchant formulated with a combination of ingredients that provide greater stability to microbial intrusion of the quenchant. Many of today’s induction hardening applications require the use of polymer quenchants on a wide variety of parts. Unfortunately, due to production requirements, parts may not be washed prior to heat treatment and pre-heat treatment process fluids such as machining coolants, rust preventives, and cleaners can contaminate the quench tank. These products can cause degradation of the quenchant. Aqua-Quench 145 is specifically designed for use in induction and immersion hardening applications to minimize residual sticky deposits on equipment and quenched parts, and extend system life. The quenching speed of Aqua-Quench 145 solutions can be selected to suit the steel hardenability and components requirements by varying the concentration of the solution.
