6. Heat Treatment
AnnealingSAE 4140 alloy steel is usually supplied ready heat treated to hardness in 18-22 HRC. If further heat treatment is required, then heat to 840 oC - 875 oC, hold until temperature is uniform throughout the section, soak for 10 - 15 minutes per 25 mm section, and quench in oil, water, or polymer as required.
