nm500 steel equivalent grades H beams
The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy NM500 steel equivalent grades products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of NM500 steel equivalent grades stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.
ASTM a588 steel beam NM500 steel equivalent grades not only has high tensile and yield strength, but also has good atmospheric corrosion resistance due to its small copper content. Due to its high strength, its NM500 steel equivalent grades weight is less than that of A36 steel section without reducing strength. At the same time, it is the best material for outdoor application, the surface is orange.
With equipment, technology, production technology, quality supervision and other leading advantages, we are leading in the production of all kinds of high-quality, high-tech medium, extra thick, extra wide steel plate NM500 steel equivalent grades shaped parts. The cutting surface is smooth and clean, the cutting edge is neat, without secondary processing by users, and it can be installed and used directly according to the technical dimensions, with the characteristics of high coincidence rate of positive and negative tolerance and excellent quality. The processed steel products are mainly used in heavy machinery and equipment.
The preparation of NM500 steel equivalent grades galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for NM500 steel equivalent grades centralized control, two-layer welding process, reducing the possibility of incomplete penetration.
GB standard wear resistant steel plates parameters: The standard for Chinese wear plates is GB/T 24186, which includes NM400, NM450, NM500, NM550, NM600 etc. steel grades. According to the standard, the NM400 plate thickness is no more than 80mm, and hardness is 370-430HBW. NM500 steel equivalent grades, NM450 plate thickness is no more than 80mm, and hardness is 420-480HBW. NM500 plate thickness is no more than 70mm, and hardness is 470HBW min. And NM600 plate thickness is no more than 60mm, and hardness is 570HBW min.
The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel NM500 steel equivalent grades products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
