Are there tests to determine double tempered? in Heat Treating, general discussion Posted August 2, 2012 We have a 80 pound steel casting (0.3% C max, 1.85%Mn max, Si 1.5% max) that is quenched and double tempered. Is there a test (hardness, microstructure, etc.) we can do to determine if it was double tempered or tempered just once?
