Gulf Quench series  are  normal  speed  quenching  oils  developed  for  heat  treatment  of  ferrous  metals  in  a  wide variety of quenching operations. These oils are formulated from highly refined paraffinic oils to provide superior ageing stability. They possess good inherent thermal and oxidation stability offering long service life with minimal deposit formation. Their low volatility c haracteristics reduce oil loss from vaporisation and the  uniform  heat  dissipation  property  mi nimises  stress  and  metal  distortion  ensuring  uniform  hardness.  These   oils  are  available  in  two  viscosity  grades  and   are  recommended  for  normal  speed  quenching  of  ferrous   metals such as carbon steel, gray iron and alloy steels.
