Cooling Characteristic Test of Quenching Media
Two test methods: JB/T 7951—2004 (Industrial quenching oil-determination of cooling characteristics nickel-alloy probe test method) and SH/T 0220—1992 (Heat Treating Oils–Determination of Cooling Ability) relating to the characterization of cooling characteristics of quenching media have been introduced in China. However, a number of problems were encountered which necessitated an error analysis study and the establishment of a benchmarking method. The results of this work are discussed here.
