What is xar400 wear resistance material equivalent steel grade in China

Normalizing is a special case of annealing, the effect is similar to annealing, but the microstructure obtained by normalizing is finer. For low or medium carbon steel, normalizing can improve hardness and machinability. For xar400 wear resistance material medium carbon steel and low alloy steel, normalizing can refine grain and uniform structure and reduce hardness. For high carbon steel and high alloy steel, normalizing can eliminate the network carbide produced by forging and improve the homogeneity of the preparation heat treatment structure.

On Jan. 31, 2019, BBN steel held the annual meeting with all employees, family members, and friends. It is a moment of joyand it is a moment to summarize the past and look forward.Looking back on 2018, BBN steel exported xar400 wear resistance material more than 2 million tons of steel materials to all parts of the world and made outstanding contributions to infrastructure construction at home and abroad. In 2019, BBN steel will make persistent efforts and forge ahead.

Water cutting machine is called water knife for short, that is, water is used as knife. High pressure water jet cutting technology can perform any curve cutting process on any material, xar400 wear resistance material included. The heat generated in the cutting process will be immediately taken away by the water jet without harm. Material, no need or easy to reprocess after cutting, safety and environmental protection, faster, faster, more efficient.

The wear-resistant layer of xar400 wear resistance material wear-resistant steel plate is mainly composed of chromium alloy, and other alloy components such as manganese, molybdenum, niobium and nickel are added. The carbide in the microstructure is distributed in the form of fiber, and the direction of the fiber is perpendicular to the surface. The microhardness of carbides can reach hv1700-2000 and HRC58-62 respectively. The alloy xar400 wear resistance material carbide has strong stability at high temperature, high hardness and good oxidation resistance. It can be used normally within 500 ℃.
