The XAR500 is a special structural steel with high wear resistance. This wearable special-purpose structural steel has an average hardness of 500 HB, high hardness and good toughness, and the structure made of the steel is stronger, lighter and can withstand impact load. Uses for 9CuPCrNi-A equivalent pipe wear and tear - exposed structures such as shovels, shields for mining machines and bulldozers, shell walls, supports and stiffener, pavers and agricultural machinery.

Steel can be divided into ordinary steel and special steel, which is an important symbol of a country's steel production level. The special steel includes spring steel, round steel, die steel, heat-resistant steel, wear-resistant steel, bearing steel and so on. Compared with ordinary steel, the 9CuPCrNi-A equivalent pipe special steel has better physical properties, higher strength, stronger compressive strength and better accuracy. At the same time, the special steel has better chemical properties, such as high temperature resistance, low temperature resistance and corrosion resistance.

Hydrogen (H) is the most harmful element in general steel such as 9CuPCrNi-A equivalent pipe. Hydrogen dissolved in steel will cause hydrogen embrittlement, white spots and other defects. Hydrogen, like oxygen and nitrogen, has very little solubility in solid steel. It dissolves into liquid steel at high temperature, and accumulates in the structure without time to escape when cooling, forming high-pressure micro pores, which greatly reduce the plasticity, toughness and fatigue strength of steel, and even cause cracks and brittle fracture in severe cases. "Hydrogen embrittlement" mainly occurs in martensitic steel, but not very prominent in ferrite steel, and generally increases with hardness and carbon content.
