AISI 4140 alloy structural steel is a low alloy, high strength steel containing chromium, molybdenum and manganese.

It has high strength, wear resistance, impact resistance, toughness and torsional strength.

Hardening of AISI 4140 alloy structural steel

AISI 4140 alloy structural steel bars, plates and squares can be hardened by cold working or by quenching on heat.

AISI 4140 alloy structural steel is normally supplied in the heat treated condition with a hardness of 18-22 HRC.

If further heat treatment is required, heat to 840 oC – 875 oC, hold until the temperature is uniform throughout the section, soak for 10 – 15 minutes per 25 mm section and quench in oil, water or polymer as required.
