Quenching Oils

Description

PACIFIC Quench Oils are high-quality oils developed for heat treatment of ferrous metals in a wide variety of quenching operations. They are formulated to provide deep and uniform hardening with minimum distortion and cracking for a smooth surface finish.

PACIFIC Quench Oils are available in four grades: 22, 22MS, 22HS and 32HS. The 22 grade is a highly refined, straight (non-additized) paraffinic mineral oil recommended for conventional quenching of ferrous metals at bath temperatures up to 150 °F (66 °C). It has a slower quench speed than the other grades, and provides minimum hardening power. The other three grades are fortified with select additives to provide enhanced oxidation resistance and metal-wetting ability for use in fast quench operations where it is important to develop maximum hardness while minimizing distortion. The 22MS grade is a medium-speed quench oil with moderate hardening power. The 22HS grade is a high-speed quench oil with moderate-to-high hardening power. The 32HS grade is higher viscosity, high-speed quench oil that provides the highest hardening power.

PACIFIC Quench Oils provide a high initial cooling rate to induce maximum hardness. After the critical transformation temperature is passed, the cooling rate gradually decreases to a much slower rate to minimize the possibility of stress and metal distortion, thereby ensuring a smooth surface finish. These oils are highly stable throughout the hardening temperature range to provide long service life with minimal sludge formation. They have a high viscosity index for minimum viscosity change during the entire quenching operation, and have high flash and fire points to minimize fire hazards.

  • Controlled cooling rate to minimize cracking and distortion
  • Good surface finish
  • Excellent oxidation resistance and thermal stability
  • High flash point for fire safety
