standard of nm450 wear-resistance tensile strength
Recently, a symposium on the celebration of the 70th anniversary of the founding of the People's Republic of China by the iron and steel industry was held in Beijing Convention Center. The 2019 Year of the Pig is the 70th anniversary of the founding of the People's Republic of China. Growing up with the motherland, BBN standard of NM450 wear-resistance Steel Staff sang songs to the mark the 70th victory anniversary. In the last of September, Henan BBN Steel organized all employees to sing ""My Country and I"" and made a film.
In the final analysis, the market competition is the competition for customers. Whether selling products or services, the final customer satisfaction is the standard to test the success or failure of marketing work. The so-called after-sales service is to fully understand customers, study customer psychology, pay attention to after-sales details, improve work shortcomings, improve service quality, and Exchange customer brand loyalty through the whole process of quality service.
ST52 steel angle steel with carbon content of 0.23% and yield point strength of 355 MPa is suitable for weldable and supporting members. In terms of chemical composition and mechanical properties, s355n is similar to standard of NM450 wear-resistance en10025 - 3. Compared with ASTM A36, ST52 has higher strength and better welding performance. It is also used in daily life and industrial applications such as warehouses, equipment, etc. Note: although similar standard of NM450 wear-resistance properties are shared, they are a little different. Please let us know your detailed requirements and we will tell you the most suitable steel grade.
Q235 is a kind of carbon steel. standard of NM450 wear-resistance, Q235 steel is widely used in steel structure construction because of its good toughness, good plasticity, certain elongation, good welding performance and heating performance. Q235A steel plate contains C ≤ 0.22%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.050, P ≤ 0.045. Q235B steel plate contains C ≤ 0.20%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.045, P ≤ 0.045. Q235C steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.040, P ≤ 0.040. Q235D steel plate contains C ≤ 0.17%, Mn ≤ 1.4%, Si ≤ 0.35%, S ≤ 0.035, P ≤ 0.035.
In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.
The company specializes in hot rolled plates producing, steel plate processing, steel plates cutting, carbon steel plate weldding and exporting of wide and thick steel plates. BBN company has high-quality CNC standard of NM450 wear-resistance steel plate cutting processing equipment, professional technical personnel, and supporting marketing and after-sales service system.
