Very fast, uniform cooling reduces the probability of part cracking and distortion and improves part surface hardness and durability.
Intensive quenching, known as IntensiQuench(sm), is an alternative way to harden steel parts. IntensiQuench processes can be defined as cooling (usually using pure water or low-concentration water/salt solutions) at a rate several times faster than the rate of conventional quenching. Intensive quenching requires very high cooling rates for parts within the martensitic phase. Very fast and very uniform part cooling reduces the probability of part cracking and distortion, while improving the surface hardness and durability of steel parts.
