Quenching involves the rapid cooling of a metal to adjust the mechanical properties of its original state. To perform the quenching process, a metal is heated to a temperature greater than that of normal conditions, typically somewhere above its recrystallization temperature but below its melting temperature. Quenching oils are widely used in process industries manufacturing High speed tools, Ball bearings, Nut bolts, Bright Bars, Automotive leaf springs, Gears, Tools, Dies, Fasteners , Automotive components, Transmission components, Transmission gears, Carbon steel, High-alloy steel etc
