What are the equivalent steel grades of nm400 equivalent material?

The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our NM400 equivalent material steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge NM400 equivalent material steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.

Main product: low-temperature boilerplate, pressure vessel plate, NM400 equivalent material high-strength plate, Q245R, Q345R grade, Q420C, Q690C, Q690D, Q345R steel plate, A516 Gr 70, A572 Grade 50 equivalent. The company's long-term and stable cooperation relationship with major steel mills ensures that the company provides excellent products and high-quality services to new and old customers, and strives to build a first-class marketing system in the industry.

The advantages of NM400 equivalent material, seamless steel pipe are high pressure resistance, good toughness, long pipe section and few joints. It is widely used and the rolling technology of domestic steel mills is also very mature. Compared with round steel, the weight of seamless steel pipe is lighter under the same strength. Seamless steel pipe manufacturing ring parts, can improve the utilization of materials, simplify the manufacturing process, save materials and processing time. Compared with the welded pipe, there is no weld on the outer surface of seamless steel pipe, and it has good compression resistance.

NM400 equivalent material, Stainless steel relies on a very thin, solid, fine and stable chromium rich oxide film (protective film) formed on its surface to prevent oxygen atoms from continuing to infiltrate and oxidize, so as to obtain the ability of corrosion resistance. Once the film is damaged for some reason, the oxygen atoms in the air or liquid will continuously penetrate or the iron atoms in the metal will continuously separate, forming loose iron oxide, and the metal surface will be continuously rusted.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. NM400 equivalent material, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our NM400 equivalent material products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.

Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
