Because of its high hardness, high strength and high toughness, NM450 wear-resistant plate is obviously a wise choice for those occasions with serious wear. NM400 pdf, NM450 wear-resistant plate is easy to machine, bend and weld. The high wear resistance of NM450 wear-resistant plate extends the service life of dump truck body, excavator bucket, crusher and similar equipment.
The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as NM400 pdf, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.
Thin NM400 pdf, steel plate is mainly used in automobile industry, aviation industry, enamel industry, electrical industry, machinery industry and other departments. The main requirement of thin steel plate is to facilitate bending and forming. The thinner the steel plate is, the easier it is to bend. The common specifications of thin steel plate include thickness less than 4mm, width about 500-1500mm and length about 1.5-4m.
Today, the prices of black commodity futures market fluctuated upward. The mentality of the spot market is optimistic, and the quotations of NM400 pdf merchants continue to rise. However, downstream users are more cautious in purchasing, and they basically purchase on demand. Some speculative demands have the willingness to replenish at low prices. At present, there are relatively few NM400 pdf inventory resources in the market. In addition, the cost of resources in the later stage is relatively high, so businesses are not willing to sell at low prices. On the whole, there are not many short-term new arrival resources, and the shipping pressure of merchants is not big, and the NM400 pdf price still has certain support. It is expected that the price of NM400 pdf will fluctuate and be stronger tomorrow.
