Product Description

Product Introduction:
If common quenching oil is used for thick and large workpieces or workpieces with poor hardenability, problems could occur such as soft spots, low hardness and insufficient depth of hardening layer. The KR108 Over Speed Quenching Oil is faster in cooling speed and more stable in performance, which avoids the above problems, and obtains high and uniform surface hardness and enough depth of the hardened layer.

Product Features:

1.Short vapor film stage, fast cooling at high and medium temperature stage, and has an appropriate cooling at low temperature stage.
2.For medium and large workpieces, high and uniform surface hardness and enough hardened depth can be obtained, and the deformation of workpiece can also be well controlled.
3.Good thermal oxidation stability and long service life with stable cooling character.
4.Nice brightness, low oil consumption and low use cost.
