thickness range of hardox 500 strip and coil
Hydrogen (H) is the most harmful element in general steel such as thickness range of HARDOX 500. 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.
TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the thickness range of HARDOX 500 steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.
The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
According to the hardness from HB400 to 600, wear-resistant plates can be divided into NM400, NM450, NM500, NM550, NM600 and so on. Because of its toughness, the wear plate can accept impact, sensation, bump, scratch and prick day after day. With its good processing performance, wear-resistant plate, thickness range of HARDOX 500 can be bent, formed and welded, and can prevent the occurrence and propagation of cracks, which is also the reason why wear-resistant plate can be used as structural steel.
