BBN sales impact resistance of nm400 steel plate steel mechanical properties
Wear resistant steel plate is often used for construction machinery and equipment manufacture, such as excavators, scrapers, sand making machines, etc., which operate repeatedly in the sediment for a long time. That requires the wear resistant steel plate have good wear resistance. Otherwise, once the mechanical equipment is damaged, the progress of the whole project will be greatly affected. impact resistance of NM400 steel plate, Wear resistant steel plate can also be used for building equipment, such as excavation machinery, shovel transport machinery, compaction machinery, engineering lifting machinery, piling machinery, etc.. They need long-term contact with all kinds of sediment, and need the support of wear resistant steel plates.
The addition of Ca element in steel such as impact resistance of NM400 steel plate can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.
Steel impact resistance of NM400 steel plate exports fell sharply year on year. According to the data of the General Administration of customs, 7.811 million tons of steel were exported from January to February, a year-on-year decrease of 27.0%; 2.041 million tons of imported steel, a year-on-year increase of 2.1%. Steel prices continue to fall. According to the monitoring of China Iron and Steel Industry Association, China's steel impact resistance of NM400 steel plate composite price index at the end of January was 105.48 points, down 0.58% month on month; at the end of February, the index continued to decline to 100.39 points, down 4.83% month on month.
