The points need attention to purchase wear resistance of nm400

The bridge steel plate wear resistance of NM400 produced by BBN company has pure steel, flat and smooth plate surface, small difference between plates, -40 ℃ impact value and aging impact value are stable, and the margin is large. Bridge steel plates can be controlled by rolling, cooling, normalizing, and tempering organize production with different production processes. This bridge steel wear resistance of NM400 is widely used in the manufacture of large railway bridges and highway bridges.The company has allocated special environmental protection facilities for all wear resistance of NM400 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, wear resistance of NM400 steel mill scale, environmental protection dust has reached 100%.If the chromium content in wear resistance of NM400 alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel,wear resistance of NM400. controlled rolling is that, on the basis of adjusting the chemical composition of wear resistance of NM400, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of wear resistance of NM400.We are willing to cooperate sincerely with you with high-quality wear resistance of NM400 products and sincere service to expand the market and create brilliant! We will work hard to create a first-class steel company and provide you with faster and more considerate after-sales services! Moreover, our shipbuilding steel plates have been certified by the nine countries' classification societies including DNV, ABC, GL, LR, BV, CCS, RINA, NK, and KR. The quality assurance system has passed ISO9001-2000 standard certification.
