At present, China's wear-resistant steel plate grades are divided into six levels, namely NM300, NM360, NM400, NM450, NM500, NM550 and NM600. The wear-resistant steel grade adopts the combination of Chinese NM of wear resistance meaning and Brinell hardness (HB) value. For example: NM500, NM is the first universal parent of Chinese "wear resistance", "500" is Brinell hardness value. NM series wear-resistant steel has good wear resistance, which greatly reduces the loss and use cost. ABS D40 submarine
hull steelThe company has allocated special environmental protection facilities for all pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, steel mill scale, environmental protection dust has reached 100%.ABS D40 submarine hull steel,We can produce steel plate, steel pipe, steel coil, and also carry out a series of processing services, steel plate cutting, welding, etc. we have advanced production technology and production equipment, which can meet the needs of customers to the greatest extent. Whether it is deep processing or cutting, we will communicate with customers in detail to choose the best processing method and production technology.ABS D40 submarine hull steelThe performance of heat treatment process reflects the difficulty of heat treatment and the tendency of defects of the steel. It mainly includes hardenability, superheat sensitivity, temper embrittlement tendency and oxidation decarburization tendency. The hardenability of alloy steel is high. The cooling method can be used slowly during quenching, which can reduce the deformation and cracking tendency of the workpiece. The addition of Mn and Si will increase the superheat sensitivity of steel. The strengthening effect of alloy elements on steel in quenching and tempering state is the most significant.ABS D40 submarine hull steelSince its establishment, the company has been deeply supported and loved by customers with its unique business philosophy and business model The company has always adhered to the tenet of "credibility first, integrity-based, quality first" and sincerely serves new and old customers At the same time, it keeps pace with the times based on market orientation, continuously expands offline channels, and gradually establishes a complete online E-commerce business management platform We will always promote our after-sales service to make client satisfied with our goods,ABS D40 submarine hull steel.
