China supplier high strength nm500 steel equivalent grades price

The basic phases of NM500 steel equivalent grades, structural steel in the annealed state are ferrite and carbide. The alloy elements are dissolved in ferrite to form alloy ferrite, which depends on solid solution strengthening to increase strength and hardness, but at the same time reduce plasticity and toughness. The addition of alloying elements reduces the carbon content of the eutectoid point, which increases the proportion of pearlite in the structure and reduces the distance of the pearlite layer. This also increases the strength of the steel and reduces the plasticity.

NM500 steel equivalent grades, Wear resistant steel plate is a kind of special plate product used under the condition of large area wear. At present, the commonly used wear-resistant steel plate is made by cladding a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance on the surface of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity. In addition, there are cast wear-resistant steel plate and alloy quenching wear-resistant steel plate.

Strip steel is a kind of steel plate with thin thickness, narrow width and long length. Strip steel can be made of common carbon steel, carbon structural steel, spring steel, tool steel, stainless steel, etc. Strip steel has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. There are many kinds of strip steel, NM500 steel equivalent grades. Hot rolled steel strip is mainly used for cold-rolled billets, cold-formed steel billets, welded steel pipe billets, manufacture of bicycles and small hardware products.

Previously, the coke market was both prosperous in supply and demand, and steel mills' blast furnaces were limited by the environmental protection restrictions in autumn and winter. The operating rate continued to be high, and the demand for coke remained unabated. With the continuous advancement of the coking capacity reduction process, the price of metallurgical coke will be in a price increase channel for a long time, and the mismatch of supply and demand is difficult to alleviate in the short term.
