Exol Excelquench Quenching Oils

Excelquench 601 grade is specially formulated, highly refined paraffinic general-purpose quench oil. When a piece of steel, containing sufficient carbon, is cooled rapidly it becomes considerably harder than it would if allowed to cool slowly. The preferred quenchant is one, which removes heat slowly in the vapour stage and rapidly in the vapour transport stage. The quenchant must also remove heat slowly in the liquid cooling stage when the metal is completely wetted by the fluid in order to reduce distortion. The Excelquench range of quench oil have been formulated to promote uniformed rates of cooling. They do not readily oxidise and have a naturally high flash point.
