nm500 plate application material heat treatment

,NM500 plate application., Large diameter spiral steel pipe refers to the relatively large diameter spiral steel pipe, which is generally required to be more than 1000mm. The manufacturing process of large-diameter spiral steel pipe: first, the steel strip is bent into shape, and then welded together to make a large-diameter spiral steel pipe of specified size. After being processed into a pipe, hydrostatic test, bending, flattening and other tests shall be carried out, and the internal steel support of large-diameter spiral steel pipe can be made according to customer requirements.The company is a large NM500 plate application steel supplier and exporter specializing in steel coil, steel plate, steel tube and section steel. The company has always put service and quality first, offered reasonable price, taken small profits and quick turnover as the principle, honest and trustworthy as the purpose. The success of the company is not only the hard work and wisdom of all the employees of the company, but also the deep love of our customers. We will continue to achieve new leaps and create greater brilliance of the NM500 plate application enterprise, and make our own contribution to the development of the world economy.Hot rolled NM500 plate application steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the NM500 plate application processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.Q355GNHE corten steel is characterized by adding a small amount of Cu, P, Cr, Ni and other alloying elements to the steel, so that the steel material forms a dense layer between the rust layer and the substrate with a thickness of about 50 to 100 μm and good adhesion to the substrate metal. The amorphous spinel oxide layer prevents oxygen and water in the atmosphere from penetrating into the steel substrate, slows down the rust development to the steel material, NM500 plate application, and greatly improves the steel material's resistance to atmospheric corrosion.First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
