KR218H Fast Bright Quenching Oil offers high cooling speed and stable performance, making it particularly suitable for quenching large-module gears, large cross-section bearing rings, bearing rolling elements, textile components, sewing machine parts, and hardware tools. It performs exceptionally well under protective or controlled atmosphere conditions, ensuring effective quenching results for these types of 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, providing 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.
