AISI 4340 Steel. AISI 4340 Steel is a nickel chromium molybdenum alloy steel that widely used in Oil & Gas industry.It is a quality high tensile alloy steel. 4340 steel offers toughness and high strength in the heat treated condition. AISI 4340 is usually supplied under quenched and tempered condition at the hardness of 24 – 29HRc.
4340 steel, a chrome nickel-moly alloy, comes in a variety of forms and conditions and is widely used for high stress parts. It exhibits high fatigue strength in large cross sections and has excellent transverse ductility & toughness at high strength levels.
The entire steel manufacturing process determines the strength of these materials, as well. A simple designation of 4340 steel does not necessarily mean that two steel suppliers construct the final product to the same standards or with the same processes. “Not all 4340 alloy steel is the same,” says Leach.
