Over Speed Quenching Oil KR105
When using conventional quenching oils for thick, large workpieces or those with low hardenability, issues such as soft spots, low hardness, and insufficient hardened layer depth often arise. KR105 Over speed Quenching Oil, with a faster cooling rate than similar quenching oils, effectively addresses these issues. It enables the workpieces to achieve high and uniform surface hardness, along with sufficient hardened layer depth.
