Product Introduction
Products Description 

35NiCrMoV12-5 is an alloy structural steel material used for manufacturing ultra-high strength components. In the quenched and tempered condition, 35nicrmov12-5 steel round bar has high strength, excellent toughness, and plasticity. After quenching and low-temperature tempering, it has high strength. The hardenability of 35nicrmov12-5 in q+t state is superior. Generally sized parts can be quenched in air and are sensitive to notches and corrosive environments.

Production Description

35NiCrMoV12-5 Steel Round Bar +QT

 

35NiCrMoV12-5 alloy steel contains chromium and nickel elements, which are beneficial for improving the wear resistance of the steel. Under friction and wear conditions, its wear resistance is better than carbon steel and other low alloy steel materials. The cutting performance of 35NiCrMoV12-5 steel is very good, and it can be used for mechanical processing such as turning, milling, and drilling. Its heat treatment process is stable and can be subjected to surface treatments such as carburization and nitriding, further improving its wear resistance and corrosion resistance.
After reasonable heat treatment, the microstructure and mechanical properties of 35NiCrMoV12-5 steel round bars can be changed. For example, higher strength and toughness can be achieved through quenching and tempering heat treatment.35NiCrMoV12-5 material can obtain a harder surface layer and better wear resistance By carburizing or nitriding treatment.

Due to its excellent performance characteristics, 35NiCrMoV12-5 steel is widely used in various mechanical components and tool manufacturing. For example, it can be used to manufacture high-strength bolts, nuts, shaft components, gears, wear-resistant plates, etc. In addition, it can also be used to manufacture high-precision and high demand mechanical components such as medical devices and aerospace vehicles.
