Handbook: Everything You Should Know About 4140 Steel

The purpose of these processes is to enhance the physical and mechanical properties of this steel. 4140 steel is annealed at 872°C which is equivalent to 1600°F. After that, the steel is cooled in a furnace. On the other hand, 4140 steel has tampered at the temperatures of between 200°C and 650°C.

AISI 4140 Alloy Steel (UNS G41400)
AISI 4140 Alloy Steel (UNS G41400)

AISI 4140, alloy ,steel, can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the ,steel, can be increased if it has a lower tempering temperature. For example, a tensile strength of 225 ksi can be achieved by tempering at 316°C (600°F), and tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F).

This alloy has high strength, high fatigue strength, toughness, torsional strength, and impact and abrasion resistance. Additionally, 4140 steel is highly ductile when annealed, though it requires more pressure as it is tougher than most carbon steels. 4140 is easily welded, but if this is done after hardening, it will also require a post weld heat ...
