Product Introduction:
With the development of less, non-oxidation and clean heat treatment technology, the surface quality requirements of workpieces after heat treatment are getting higher and higher. The use of KERUN® KR028 bright quenching oil can make workpieces heated under a protective atmosphere or a controlled atmosphere condition to obtain good surface brightness (metal color) after quenching.
Product Features:
1.Good brightness, can keep the brightness of workpiece surface under the condition of no oxidation heating (metal color)
2.Less oil belt consumption, the workpiece is easy to clean;
3.Thermal oxidation stability is good, which can keep long-term stable use of oil products.
