Quenching deformation is one of the three primary challenges in heat treatment quality control. KR4188 Isothermal Graded Quenching Oil effectively reduces quenching deformation in thin-walled, complex-shaped workpieces such as automotive gears, motorcycle gears, clutch plates, and bearing rings. This results in improved product precision, reduced machining allowance, and significantly lower production costs.
Advantages
● Short vapor film phase, moderate high-temperature cooling rate, and slower low-temperature cooling rate, allowing for high and uniform surface hardness and sufficient hardening depth, while effectively controlling quenching deformation;
● Good thermal oxidation stability, maintaining long-term stable cooling characteristics and a long service life;
● Bright finish, low oil carry-off, and low usage cost.
