Park's AAA

The world's most widely specified accelerated fast oil quenchant. It is capable of quenching a variety of steels, sized and shaped parts with little or no change in operating parameters. AAA Quench Oil achieves faster cooling rates through intensified action in the initial stages. This, and slower cooling through the martensitic transformation range, minimize hardness to a greater depth. AAA Quench Oil is suitable for integral quenching and ideal for carbon, low and medium alloy steels.
