Performance of vegetable oils as a heat treat quenchant
- Univ. of Northern Iowa, Waverly, IA (United States)
The purpose of this study was to establish as a reference the base line performance of several vegetable oils as a quench medium. Furthermore, the project was funded by the Iowa Soybean Promotion Board to investigate the potential use of soybean oil as a quench medium. Several commodity and genetically modified seed oils (high oleic) were first tested in a {open_quotes}quenchalizer{close_quotes}. Also, 300 pieces of SAE 1524 steel bars were heat treated and quenched in a chemically modified (partially hydrogenated) soybean oil and in a control (paraffin) oil. Results included changes in the oil in terms of viscosity and cooling rate and in the steel in terms of hardness. Vegetable oils can perform as quench media, but they would require treatment to improve oxidative stability among others. Advantages of vegetable-based quenchants include: renewability, environmental-friendliness and potential benefits in terms of human safety and higher flash point.
