After comprehensive and professional training such as customer service, the customer service team has more strict discipline in the management of customer service team to ensure that customer service personnel respond to customers with a professional attitude. A process supervision system has been set up to let each customer supervise the process of the system with us
The SA 516 grade 60 steel is remarkably one of the standard steel grades having five chemical elements that are specified with the three mechanical properties. The grade does not require to be heat treated; hence it offers the best properties and features. Our aim is to provide our customers with a high quality of theNM400 weathering steel product which has all the qualities that an application requires for working. The SA 516 grade 70 plates are widely used in different applications because of its easy to use and installation process.
P235GH steel material number under EN10028-2:2003 standard is 1.0345. This steel is a European pressure vessel steel. P235GH Mechanical properties: Tensile strength σb (350 ~ 480 MPa); Yield strength σs(215 MPa min.); Elongation ≥25%; Brinell hardness ≤105 ~ 140. NM400 weathering steel, P235GH steel chemical composition (mass fraction,%): ≤0.16 C; ≤0.35 Si; 0.60 ~ 1.20 Mn; ≤0.025 P; ≤0.010 S; ≤0.30 Cr; ≤0.30 Ni; ≤0.30 Cu; ≤0.08 Mo; ≤0.02 V; ≤0.02 Nb; ≤0.012 N; ≤0.020 Al; ≤0.03 Ti.
BBN steel had provided Grind plates for more than 15 years for widely applied in equipment, Engineer machinery etc. In 2018, one of our India customer visit our NM400 weathering steel office and work shop to discuss Q235B Grind plate technical request, they have strict surface and thickness tolerance, and they also request UT and MT for testing. As a result, they purchase NM400 weathering steel 179 tons as trial order for first cooperation. And have good comment on our quality. Till now, we keep exporting around 100 tons per month as regularly.
BBN steel strictly control quality of our carbon steel plate, alloy steel plates and structural steel plates. For NM400 weathering steel ASTM A572 Grade 50 structural steel plate, Our Q/C Department will inspect dimension before shipment, making sure structural steel plate thickness tolerance and width, length tolerance are matchable to the NM400 weathering steel standard requirements. The company is a good ASTM A572 Grade 50 structural steel plate supplier in the globle market and the head is located in China. Welcome to send us inquiry and questions about structural steel plate.
