What is ASTM equivalent of nm550 steel price list and their difference
In production and operation, the company always attaches great importance to product NM550 steel price list quality. Product quality is stable, performance index is superior, after-sales service is in place, the company's products have been exported to the United States, Southeast Asia, Africa, the Middle East and other countries and regions, occupying a large part of the overseas market NM550 steel price list. And a large number of famous enterprises at home and abroad have formed a solid strategic partnership with the company.
NM550 steel price list, Welded pipe plays an important role in modern industrial production and engineering construction, and has become one of the irreplaceable steel pipe products. Welded pipe is a kind of steel pipe made of rolled plate and steel plate after crimping and forming. Therefore, the diameter of welded pipe can be made very large and can be made according to the requirements of customers. Welded pipes can be used for water diversion, transportation of gas, air, oil and heating steam and other generally lower pressure fluids.
As a common steel plate in the steel market, NM550 steel price list, manganese steel plate has the following characteristics. First, good toughness, stretching and crimping can be done well. Second, the bearing strength of manganese steel plate is good and it can bear a lot of gravity. Third, the NM550 steel price list, manganese steel plate is easy to weld, easy to process finished products, and its price is relatively low. Fourth, manganese steel plate has good corrosion resistance, and long service life. Fifth, the manganese steel plate has good mechanical properties, low temperature performance, good plasticity and weldability.
The acicular ferrite pipeline steel can inhibit the formation of polygonal ferrite, promote the acicular ferrite transformation, and improve the precipitation strengthening effect of carbon and niobium nitride by adding molybdenum to reduce the transformation temperature of polygonal ferrite, so as to improve the strength of steel and reduce the ductile brittle transition temperature. The NM550 steel price list, tempered sorbite pipeline steel adopts the heat treatment process of quenching and tempering. The tempered sorbite structure is formed to meet the comprehensive requirements of thick wall, high strength and sufficient toughness.
20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, NM550 steel price list. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.
The boiler steel plates are among our main products. Other than standard size boiler steel plates, we also provide NM550 steel price list cutting, bending and so on processing to change plate size and shape according to your requirements.
