Factory sale wear resistance of nm400 with prime quality

Wear resistant steel is very wear-resistant: for example, excavator bucket, long-term excavation requires good wear resistance. Wear resistant steel has a very high hardness: for example, scraper conveyor, if the hardness is not up to standard, it is extremely easy to fracture, resulting in very serious consequences. Wear resistant steel has good corrosion resistance: many equipment need to transport chemical corrosion products, so corrosion-resistant mechanical equipment is needed. wear resistance of NM400, Wear resistant steel has good fatigue resistance: such as bearing steel ball, which can do fast and repeated movement, and need to guarantee performance.

Try to use wear resistance of NM400 high-quality alkaline covered electrode as much as possible, and don't use inferior electrode to save money. According to the theory of chromium poor, chromium carbide will be precipitated on the upper edge of the grain boundary of the weld and heat affected zone when the wear resistance of NM400 temperature range is between 450 ℃ and 850 ℃, resulting in chromium poor grain boundary, which is insufficient to resist corrosion.

South Korean wear resistance of NM400 steel industry said that the slowdown in economic growth superimposed on the impact of the epidemic, steel demand weakened, exports were sluggish, enterprises are facing huge operating pressure. Due to the delay in the resumption of work of Chinese wear resistance of NM400 steel enterprises, the steel inventory is growing rapidly. According to statistics, China's steel circulation inventory reached 23.75 million tons in February, the highest since 2006, with an estimated total inventory of 33.45 million tons.

Common wear resistance of NM400, steel plate thickness specifications are as follows: Thick steel plate: thickness greater than 4, width within 10 is less than 2000mm, width above 10 is generally 2000, 2500mm, length 4-12m; Thin steel plate: thickness less than 4mm, width 500-1500mm, length 1.5-4m; Flat steel: thickness 4-60mm, width 12-200mm, length 3-9m.
