Critical cooling rate

WebOct 28, 2024 · The critical cooling rate is the rate of cooling that is fast enough to transform austenite into 100% martensite. In welding, this can be achieved by quenching … WebOct 15, 2024 · The rate of cooling necessary to harden the part is called the critical cooling rate. It is the minimum cooling rate that will achieve the maximum hardness. If the part is cooled at higher rates than the critical cooling rate, no additional hardness will be achieved, but may cause excessive distortion and possibly cracking.
