The difference between A36 and nm550 steel chemical composition
Our company's NM550 steel chemical composition power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the NM550 steel chemical composition utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
Cold rolling steel is made of hot rolled coil under recrystallization temperature at room temperature. Cold rolled steel sheet is produced by cold rolling process, which is called cold plate. The thickness of NM550 steel chemical composition, cold rolled sheet is generally between 0.1 mm and 8.0 mm. The thickness and width of cold rolled sheet produced by most factories are less than 4.5 mm. The thickness and width of cold rolled sheet are determined according to the equipment capacity of each factory and market demand.
Compared with carbon steel, low alloy steel has many advantages, such as high strength, good plasticity and toughness, good weldability, good cold and hot pressure processing performance, better corrosion resistance, etc. Due to the increase of NM550 steel chemical composition metal composition, the yield point of low alloy steel structure is higher than that of ordinary carbon steel, so it is light and suitable for structural parts application. The low alloy steel is one of our main products.
Different from NM550 steel chemical composition, the alloy wear-resistant layer of alloy plate is mainly chromium alloy, and other alloy components such as manganese, molybdenum, niobium, nickel are also added. The carbides in the metallurgical structure are distributed in a fibrous shape, and the fiber direction is perpendicular to the surface. Carbide microhardness can reach HV1700-2000 and surface hardness can reach HRC58-62. Alloy carbides have strong stability at high temperatures, maintain high hardness, and also have good anti-oxidation properties. They are fully used within 500°C.
