The requirements for S460M specification during application

RAEX400 steel is a hardened wear-resistant steel material with an average grade of 400HBW and a Brinell hardness. The microstructure of this wear-resistant steel is a martensite structure, which can ensure the high hardness and tensile hardness of the steel plate. The hardness of RAEX400 is 2.5 times that of S355 structural steel, S460M specification. Despite its high hardness and high strength, RAEX400 steel can be formed by free bending or hemming, and has good weldability.

Since it was established in 2000. Based on the domestic rich S460M specification product resources and the great steel demand of the international market, our S460M specification service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

Quenching is a common heat treatment process. It is the metal heat treatment process in which the S460M specification metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between S460M specification strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

Oxygen (O) is a harmful element in steel such as S460M specification. Although manganese, silicon, iron and aluminum are added to deoxidize the steel at the end of steelmaking, they can not be removed completely. During the solidification of molten steel, the reaction of oxygen and carbon in the solution will produce carbon monoxide, which can cause bubbles. Oxygen mainly exists in the form of FeO, MnO, SiO2, Al2O3 and other inclusions in the steel, which reduces the strength and plasticity of the steel. Especially, it has serious influence on fatigue strength and impact toughness.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
