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 SM400B grade steel 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.The company focuses on teamwork and builds a team with a dream. For society: we focus on quality first, integrity-based, service-oriented create value for customers and wealth for the society. For employees, the company promote healthy living, happy work, unity, innovation. For working, we seek the efficient operation, the pursuit of excellence. Welcome to come, visit our office building and join us.GB/T1591-2018 Q355NB is a low-alloy high-strength structural steel. This steel has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Steel SM400B grade steel products are delivered in hot rolled, normalized, normalized rolled or thermomechanical rolled (TMCP) state.20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, SM400B grade steel. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.In January 2019, one of our Vietnam customer purchased 395.62 tons Q345B steel plate SM400B grade steel for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 SM400B grade steel and priming gray oxide primer, and arrange shipment in time.
