AQUA-QUENCH 230 has been especially developed for large systems and treatment of large forgings and castings. AQUA-QUENCH 230 is a polyalkylene glycol (PAG) based quenchant. Its slower cooling rate during the critical martensitic transformation temperature range minimizes risk of cracking and distortion and so enables the treatment of higher hardenability steels not previously suitable for quenching in conventional PAG type quenchants. AQUA-QUENCH 230 eliminates the smoke, fume and fire hazards associated with oil quenching and provides flexibility of quenching speed. Its nitrite free corrosion inhibitor system provides excellent protection to quench tank, fixtures and fittings, cooling systems and associated pipework.

 

Applications:

Aqua-Quench 230 is diluted with water in use and provides extremely uniform quenching characteristics. The quenching speed of Aqua-Quench 230 can be varied to suit the steel hardenability and component requirements by varying the concentration and temperature of the solution and the degree of agitation in the quench tank.

3% to 5% solutions improve wettability on the component surface thereby imparting a more uniform quench and preventing soft spotting frequently associated with water quenching. These low concentrations are generally used for steels of very low hardenability.

10% to 20% solutions provide accelerated quenching characteristics faster than those of accelerated quenching oils, and are therefore suitable for low/medium hardenability steels and applications where optimum hardness and mechanical properties are required.

20% to 30% solutions provide slower cooling rates suitable for a wide range of through hardening and case hardening steels.
