     Structural alloy steel 4140 steel has good workability, machining deformation small, anti-fatigue performance is quite good, is a medium hardenability steel. After the 4140 heat treatment has good strength and excellent mechanical properties, good technology, finished product rate. Maximum use temperature of 427 degrees Celsius. 4140 steel with high strength and hardenability, good toughness, quenching small deformation, high creep strength and lasting strength at high temperatures. 4140 steel can be used for manufacture forgings of higher strength and greater cross-section, such as a locomotive traction gear, turbocharger transmission gear, rear axle,  the connecting rod and the spring clips of great load, can also be used in less than 2000m deep oil drill pipe joints and fishing tools, and can be used for bending machine die etc..
