Product Description

Precision CNC machining steel parts,CNC turning 4140 steel parts

4140 steel, this steel has good machinability, small processing deformation, very good fatigue resistance, is a medium hardenability steel, 4140 has good strength and good comprehensive mechanical properties after heat treatment, good workability, yield High. The maximum service temperature is 427 degrees Celsius. 4140 strength, high hardenability, good toughness, small deformation during quenching, high creep strength and lasting strength at high temperature. It is used to manufacture forgings that require higher strength and larger quenched and tempered sections 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 for Drill pipe joints and fishing tools for oil wells below 2000m, and can be used for molds of bending machines.

Our customers are all over the world, especially in Europe and the United States. The industries currently involved in the products also include many fields, such as: intelligent robots, communication equipment, automobiles, crawler scooters, medical equipment, special testing equipment, printers, aerospace equipment and underwater detection equipment. We have the ability to work with customers from the engineering development of new products until the new products enter formal mass production. We can improve the machining process for customers in order to reduce costs and control product quality. Our own factory has many advanced CNC precision machining equipment, and we have an engineering and quality team with rich technical and management experience to ensure our services. Jinc expects to provide customers with global first-class precision parts processing products in the industry of automation equipment and fixture tools
