HOUGHTO-QUENCH® 3440 is a high performance, highly accelerated quenching oil.
  • Designed to ensure consistent performance under the most arduous of operating conditions.
  • Carefully formulated additive package is incorporated to reduce the duration of the vapor blanket cooling stage and provide accelerated quenching characteristics, together with excellent oxidation resistance and thermal stability.
  • Highly accelerated speed enables the development of optimum strength and hardness with minimum distortion in lower hardenability and low alloy steels, heavy sectioned components or steels of borderline hardenability.
  • Suitable for use in all types of quenching installations including open quench tanks, sealed quench furnaces and continuous furnaces of the shaker hearth, cast link, and mesh belt type
  • Recommended particularly for applications where staining of components during quenching should be minimized
  • Minimal drag-out of quenching oil means less smoke and makeup required
  • Excellent oxidation resistance and thermal stability means elimination of waste due to quench oil degradation
