How is the performance of equivalent grades of nm450 steel

The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating equivalent grades of NM450 steel production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.

Chinese grade of 20# steel plate: No.20American grade: ASTM1020Japanese grade: S20CGerman, British and French grades: C22, C20CMaterial No.: 1.0402, 1.0411Density: 7.85The strength of 20# steel plate is slightly higher than that of 15# steel plate, with little quenching and no tempering brittleness. equivalent grades of NM450 steel, 20# steel plate is generally used for bending and so on processing. The welding performance of arc welding and contact welding is good. When gas welding, the 20# steel plate with thin thickness and strict or complex shape is easy to crack.

The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with equivalent grades of NM450 steel, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.

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 equivalent grades of NM450 steel, 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.

A588 Grade A steel plate is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness."When propertly exposed to the atmosphere, A588 Grade A is suitable for many applications in the bare condition. equivalent grades of NM450 steel, A588 Grade Acould be produced in 200mm in our company.

The company has accumulated rich experience in long-term cooperation with new and old customers, which makes our products equivalent grades of NM450 steel more unique in the same industry, and is favored and praised by users. We always adhere to the enterprise spirit of "integrity, dedication, and people-oriented" and the business philosophy of "creating benefits for users". As a leading international steel supplier, BEBON have two warehouses which are near by Tianjin port and Shanghai port.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
