MAK Thermol

PDS

Superior heat treatment oils for outstanding performance

MAK Thermol range is a superior quality quenching oil formulated exclusively from highly refined base stock and special additive. The antioxidant additive provides excellent resistance to oxidation and break down of the oil and ensures longer operating life. These oils have very high flash points and low volatility. The range covers all quenching processes. The quenching oils allow uniform hardening of parts with improved grain structure and with minimum distortion. It provides consistent and repeatable mechanical and metallurgical properties.

 
Specifications

IS 2664:1980 [Reaffirmed 1998]

 
Applications
  • MAK Thermol 68 is used as quenching medium in general heat treatment applications where lower quenching speed is desired.
  • MAK Thermol 22 & 32 are used as quenching medium for accelerated quenching operations.
 
Benefits
