What is AISI 5140 material?

Grade 5140 steel is a high carbon alloy structural steel commonly referred to as SAE 5140, governed by ASTM A506, or AISI 5140. Grade 5140 steel is a popular steel grade that can be tempered and quenched, which improves the toughness, plasticity, and wear resistance of the steel.

What is the difference between 4140 and 5140?

In terms of use, 4140 steel can be used for engineering structural parts, like high tensile shafts and gears. B:5140 steel is often used for low and moderately stressed parts for vehicles, engines, and machines where a hard, wear-resisting surface is needed.
