6mm thick prime quality NM400 steel for vehicle price

In the face of domestic and foreign steel situation, based on the advantages of production and inventory, we have established our own processing center, and our manufacturing includes different types. Steel NM400 steel for vehicle surface treatment - such as steel pretreatment (shot peening and shop primer), steel galvanizing; steel structure processing - such as cutting, drilling, milling, turning, bending, welding, etc.

Our company is a specialized technical support and after-sales service organization - customer service center. At the same time, we have provided excellent technical NM400 steel for vehicle personnel and strong technical support for our company, and cultivated an excellent after-sales team for our company. Our company will appoint a full-time service manager to be responsible for the unified coordination of technical support and NM400 steel for vehicle after-sales service of the project.

The defects of NM400 steel for vehicle, wear-resistant plate in rolling process can be divided into raw material defects, surface spot defects, plate shape defects and edge defects. The so-called raw material defects refer to some defects caused by raw materials and kept or remained in the cold rolling process. The defects of raw materials usually include bubbles, inclusions, iron sheet pressing in, raw material scratches and roll marks. The stain defect of wear-resistant plate is mainly caused by the oil on the surface of strip steel and the iron powder produced during rolling, which is left on the surface of strip steel after rolling.
