MASTER QUENCHING OIL is formulated from highly refined base stocks with inherently high thermal stability to provide rapid heat dissipation.
The quenching of steel involves cooling at a sufficiently fast rate to reach desired hardness and to avoid the formation of soft constituents, cracking or distortion. When steel is quenched, the surface is cooled more rapidly than the center.
By increasing the cooling rate, the center will reach the desired full hardness. Cooling rate can be influenced by steel composition, thickness, type of quenchant, temperature and mechanical characteristics of the quench bath.
