4140 Steel
An alloy structural steel
4140 steel is an alloy structural steel with high strength, hardenability, good toughness, and small deformation during quenching.
Alloy structural steel: 4140
Implementation standard: ASTM A29/A29M-04
Characteristic
It has high strength and hardenability, good toughness, small deformation during quenching, and high creep strength and durable strength at high temperatures.
Scope of Application
4140 lost wax investment casting is used to manufacture forgings that require higher strength and larger quenched and tempered cross-sections than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and springs that are subject to extremely high loads. The clamp can also be used for drill pipe joints and fishing tools in deep oil wells below 2,000 m.
