Is 4140 Hot Rolled

Hot rolled 4140 steel bar is a medium-carbon alloy steel that has a high hardenability. This grade is also widely used for forging. Hot rolled 4140 steel also has good fatigue and impact resistance after heat treating.

What type of material is 4140?

4140 steel is a chromium, molybdenum, manganese low alloy steel plate that is known for its toughness, high fatigue strength, and high torsional strength.

What is a 4140?

AISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness.
