carbon content of NM400 price will maintain a narrow consolidation

In the past, carbon content of NM400, NM360 wear-resistant steel plates generally do not add tungsten. However, after adding the alloying element tungsten, the carbides distributed along the grain boundaries are greatly reduced, the acicular carbides in the crystal disappear, and there are a large number of granular carbides in the crystal. Tungsten reduces the precipitation of carbides and is spherically dispersed in the austenite crystals, which is beneficial to improve the strength and toughness of the NM360 wear-resistant steel plate.

The difference between carbon content of NM400, hot rolled sheet and cold rolled sheet: hot rolled sheet has low hardness, easy processing and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The cold rolled sheet is mostly used in automobile manufacturing and electrical products. Therefore, the two have their own characteristics. According to these characteristics, it is more appropriate to choose the right rolled plate to maximize its effect and benefit.

The mechanical properties of carbon content of NM400 steel plate are related to elastic or inelastic reaction or related to stress-strain relationship. Tensile strength, yield point, elongation and impact absorption energy are the main indexes to express the mechanical properties of hot rolled steel plate. Its value represents the ability of steel carbon content of NM400 to resist various actions, which is the main criterion to evaluate the quality of steel material, and also the main basis for material selection and strength calculation in steel plate design.

In February, the North American steel price index was 171.2 points, up 4.6 points on a month on month basis, up 2.8%; the U.S. manufacturing PMI was 50.1%, down 0.8 percentage points on a month on month basis. Among them, the production index decreased by 4.0 percentage points, and the inventory index decreased by 2.3 percentage points; at the end of February, the utilization rate of crude steel production capacity in the United States was 82.5%, 0.2 percentage points higher than that in the previous month. This month, the ex factory prices of major steel products such as carbon content of NM400 in the Midwest steel works of the United States rebounded. Except for the steel prices remained stable, the prices of other steel products rose.
