High quality NM450 steel grade from BBN

A633Gr.C,D steel plate A537CL1/A633Gr.C,D steel plate, under ASTM-SAE standard A537CL1/A633Gr.C,D steel plate, under ASTM-SAE standard, we can regard NM450 steel grade, A537CL1/A633Gr.C,D steel plate as Fine-grain structural steels, normalised rolled steel. A537CL1 steel plate is one mainly of Fine-grain structural steels, normalised rolled steel,A537CL1/A633Gr.C,D steel plate is under ASTM-SAE standard equivalent to DIN:TStE355, EN:S355NL, which with a minimum impact energy of 20J at temperatures not lower than -20 degree and the tensile strength of A537CL1/A633Gr.C,D is 4800 to 620 MPa.

The company attaches great importance to systematic management, and has passed the NM450 steel grade ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on NM450 steel grade quality and promote brand development. The company's physical and chemical testing equipment is fully equipped and the quality management operation is standardized. Since 2002, the national, provincial, and municipal product quality inspection random inspection pass rates are all 100%.

S355NC steel offers excellent bending, flanging, cold-bordering and folding NM450 steel grade properties in both longitudinal and transverse direction. The bending radii specified below should be observed as minimum values.

NM450 steel grade, Hot rolled seamless tube is usually produced on automatic tube rolling mill. After the solid tube blank is inspected and the surface defects are removed, it is cut to the required length, centered on the end face of the piercing end of the tube blank, then sent to the heating furnace for heating, and perforated on the piercing machine.

Both parties shall confirm the NM450 steel grade material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the NM450 steel grade steel plant.
