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 occur. KR118H Fast Quenching Oil, with a faster cooling rate than similar quenching oils, effectively addresses these problems. It provides high and uniform surface hardness along with sufficient hardened layer depth, ensuring superior quenching results for these challenging workpieces.
Advantages
● Short vapor film phase, fast high and medium-temperature cooling rates, and appropriate low-temperature cooling rate;
● Suitable for medium to large workpieces, achieving high and uniform surface hardness and sufficient hardening depth, while effectively controlling quenching deformation;
● Good thermal oxidation stability and long service life;
● Stable performance, low oil carry-off, and low usage cost.
