Isothermal Classification Quenching Oil KR4188
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.
Product Details
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.
