Heat Treating and Quenching Fluids

Alliant Chemical offers a full line of premium quenching fluids and heat-treating associated products and services.

Quenching Oils:

All Alliant Chemical quenching oils are specially formulated with a premium base oil that has exception oxidation stability and provides extended bath life. Providing overall superior quenching performance in comparison to most other products on the market.

Oxidation Stability: As an oil oxidizes it forms organic acids, thus increasing its acid number. The formation of these oxidized acids in a basic mineral oil decreases the stability of the vapor phase and increases the cooling rate of a quenching fluid. Thus, increasing the risk of distortion and cracking. By using a premium oil which is inherently oxidation stable, the ALL-QUENCH line of oils significantly reduces the formation of these acids.

High Flash Points: The ALL-QUENCH series of quenching oil all minimizes the hazard of fire by utilizing high flash point materials.

Viscosity Index: All ALL-QUENCH oils have higher viscosity indexes when compared to similar quenching oils of the same viscosity at 40°C. This means the ALL-QUENCH line has a lower tendency for viscosity to decrease as temperatures rise. Allowing quench baths to run at higher temperatures and higher tonnage of part throughput without jeopardizing the oils cooling speeds and alloy tempering.

  • ALL-QUENCH K Fast Speed Quenching Oil
  • ALL-QUENCH G Medium Speed Quenching Oil
  • ALL-QUENCH M Marquenching / Martemperting or Slow Quenching Oil

Polymer Quenchants:

The ALL-QUENCH series of non-flammable, polymeric quenchants have a wide variety of differing properties and great flexibility of quenching performance characteristics which are easily controlled through polymer selection, polymer concentration, temperature of the bath and degree of agitation. ALL-QUENCH polymeric quenchants are all water-soluble and are generally run between 5 – 30% concentrations. Once diluted, this aqueous solution of a liquid organic polymers and corrosion inhibitors produces a homogeneous solution. At temperatures above 165°F (74°C), however, the polymer separates from water as an insoluble phase, which replicates quench oil-like performance and uniformly coats alloys to ensure even temperature distribution and high hardenability. Alliant Chemical has a fully formulated line of polymeric quenchants including PAG, PVP and nitrite-free options.
