Product Description

Good Price AISI 4140 Alloy Steel Plate

Grade: AISI 4140, 4130, 5140, 5120
Executive standard: ASTM A29/A29M-04

4140 steel. This steel has good workability, small processing deformation, and good fatigue resistance. It is a medium hardenable steel. After heat treatment, 4140 has good strength and good comprehensive mechanical properties, good manufacturability, and yield high.

The highest service temperature is 427 degrees Celsius, 4140 strength, hardenability, good toughness, small deformation during quenching, high creep strength and enduring strength at high temperature.

It is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, connecting rods and spring clips that are heavily loaded, and can also be used Drill pipe joints and fishing tools for oil deep wells below 2000m, and can be used for molds of bending machines.
