When cutting and punching a part, the dimensional tolerance shall not be greater than 10% of the A36 carbon steel coil thickness of the part. If burr occurs, the limit height shall not be greater than 0.3mm. If the part is drawn from steel sheet, some other changes may be made to ensure the basic size, but if the surface affects the assembly, it should be repaired flat. After the steel plate is installed, it should be cleaned. Before installing the steel bar, it should not pile up heavy objects on it.
A36 carbon steel coil, No. 20 steel is a high-quality low-carbon steel, cold extruded, carburized and hardened steel. No. 20 steel has low strength and good toughness, plasticity and weldability. The tensile strength is 253-500Mpa, and the elongation is ≥ 24%. No. 20 steel plate is used for ships, bridges, boilers, various mechanical components, wear-resistant components, metal structures and various tools and abrasives. It can also be used to make the shell and base of large motors and various pumps, as well as the riveted, bolted and welded components of various steels.
The company attaches great importance to systematic management, and has passed the A36 carbon steel coil ISO9001 quality management system, ISO14001 environmental management system, OHSAS18001 occupational health and safety management system, and ISO 9001: 2008 certification. Insist on A36 carbon steel coil 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%.
The large diameter cold drawn seamless steel pipe is a steel pipe with an outer diameter of more than 1000mm. The large diameter seamless steel pipe is made of steel ingot or solid billet through perforation and then hot rolling, cold rolling or cold drawing. If they are long, they need to remove the redundant parts, that is, cut them out. Their length A36 carbon steel coil is suitable for the length required by the construction of steel pipes.
