Enviroquench®

Description

‍

ENVIROQUENCH® is an environment friendly water-based polymer quenchant that can provide quenching responses like that of fast quench oils. It is far superior to oil in its safety and environmental characteristics. It is non-flammable, provides desirable cooling characteristics and has more reliable control in use with little or no environmental impact.

‍

Unlike polyalkylene glycols, ENVIROQUENCH® is completely water soluble at all concentrations and temperatures. It causes little or no foaming, contains a biocide and is fortified with suitable additives to prevent multi-metal corrosion. At 25% concentration and used at 120°F with good agitation, ENVIROQUENCH® provides quenching responses at all stages that approaches those exhibited by fast quench oils. Consequently, those conditions necessary for achieving maximum hardness in steel with minimum distortion or cracking can be realized. To obtain the best results for a particular quenching application, it is highly recommended to optimize the needed operating parameters such as concentration, temperature, agitation, duration of quenching, loading pattern etc. This optimization is essential since different conditions may be required for different steel alloys or parts made of the same steel but differing in size.

Most of the polymer film deposited on metal surfaces during quenching re-dissolves back into the quenchant in the furnace thus minimizing drag-out losses. The remaining film residing on parts after quenching is quickly and completely washed off with ambient temperature tap water.

Key Properties

• An environmentally friendly water-based polymer quenchant, noted for its safety and minimal environmental impact. It is non-flammable, causes little to no foaming, and includes a biocide. It also contains additives that prevent multi-metal corrosion, enhancing its usability across various industrial applications without significant environmental detriment.
• Offers cooling characteristics similar to those of fast quench oils, making it suitable for achieving maximum hardness in steel with minimum distortion or cracking. The document notes that ENVIROQUENCH® can be used at 25% concentration with good agitation at 120°F to provide optimal quenching responses.
• A transparent liquid with a viscosity greater than 200 CPS at 77°F, a pH greater than 9.0, and a freezing point of 24°F. It is completely water-soluble at all concentrations and temperatures, which simplifies its application and handling in various settings.
• Recommended for use in a concentration range of 1-30% by volume, with operational temperatures ranging from ambient up to 200°F. It supports a velocity of over 100 feet per minute (FPM) and requires specific operational conditions to achieve the desired metallurgical transformations, suggesting a versatile application in diverse metallurgical processes.
