The alloy wear-resistant layer of the wear-resistant steel plate is mainly made of chromium alloy, and other alloy components such as manganese, molybdenum, niobium, and nickel are also added. The carbide in the metallographic structure is fibrous, and the fiber direction is perpendicular to the surface; alloy carbide It has strong stability at high temperature, maintains high hardness, and also has very good anti-oxidation performance. S420MC cold forming galvanealed coil, wear-resistant steel plate can be used normally within 500 ℃.

Compared with S420MC cold forming galvanealed coil, pressure vessel and boiler steel plates have such advantages: The pressure vessel and boiler steel should be pure, and the fracture structure of the boiler steel plate should be uniform without cracks and inclusions. Besides, the strain aging sensitivity is small, and the strain aging impact value of the pressure vessel and boiler steel plate is required to be no less than 50% of the non-aging impact value. That is why pressure vessel and boiler steel plate is first choice for fabricating pressure vessels and boilers, while S420MC cold forming galvanealed coil is not.

The heat treatment process can significantly improve the physical properties of steel, improve the compressive strength, ductility and service life of parts, and improve the hardness and wear resistance. Therefore, critical equipment parts and special tools must be quenched and tempered. The quenching and tempering treatment can also improve the production and processing performance of the S420MC cold forming galvanealed coil product workpiece, thereby improving the production efficiency and production processing quality.
