42CrMo4 Round Bar Forging

Preheat the steel carefully, heat to 1150℃ – 1200℃ maximum, hold until temperature is uniform throughout the section. Do not forge below 850℃. Following forging operation the work piece should be cooled as slowly as possible.

42CrMo4 Round Bar Heat Treatment

4140 Annealing
Heat ASTM 4140 steels to 800℃ – 850℃, hold until temperature is uniform throughout the section and cool in furnace.

4140 Normalizing
Heat steel alloy 4140 to 870℃ – 900℃, hold until temperature is uniform throughout the section, soak for 10 – 15 minutes and cool in still air.

4140 Tempering
Re-heat 4140 grade steel to 550℃ – 700℃ as required, hold until temperature is uniform throughout the section, soak for 1 hour per 25 mm of section, and cool in still air.

Hardening of 42CrMo4 4140 Round Bar

AISI alloy 4140 steel bar, plate and square can be hardened by cold working, or heating and quenching.

42CrMo4 alloy steel is usually supplied ready heat treated to hardness in 18-22 HRC. If further heat treatment is required, then heat to 840℃ – 875℃, 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.
