Market price forecast of nm500 carbon element content on 2021.03.26

The company produces and export steel plates and steel section products of various materials all year round. The width of the NM500 carbon element content thin plate is 500 - 1500 mm; the width of the thick plate is 600 - 3000 mm. Steel plates are classified by steel type, including ordinary steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, bearing steel, etc .; according to use, there are shipbuilding plate, pressure vessel plate, wear resistant steel plate, bridge builidng steel, corten steel plate, and pipeline steel plate.

The wear-resistant plate NM500 carbon element content shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and NM500 carbon element content hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the NM500 carbon element content plate should be derusted before cutting.

Affected by the weakening of the futures steel market, the market sentiment is cautious. Considering the resource cost, the NM500 carbon element content merchants have strong willingness to stand up price and follow the rise. After the price rise, the NM500 carbon element content merchants' shipment is not smooth, the transaction situation is generally weak, the downstream high level acceptance is weak, and the inventory pressure is not obvious. It is expected that the NM500 carbon element content prices will fall down and adjust in the future.
