Welcome to BBN High Strength Steels Factory
Since the foundation of the company, the Spring Festival Gala is an annual activity held at the end of the year. Now it is a part of the BBN company culture to enrich the employee's life. The annual Spring Festival Gala in 2019 was held on January 20, 2020. There are opening ceremony, leader's speech, BBN steel performance, awards for outstanding employees, lucky draw, party game, curtain call, company group photo, annual Gala dinner and other links.
Q690D steel material is a low-alloy ultra-high strength steel grade. Standard: GB/T 3077. The hardenability of steel is high, and the critical hardenable diameter in oil is 60mm (96% martensite). After quenching and tempering, steel can obtain high strength, and has certain toughness, and can be processed into shape. But cold deformation plasticity and weldability are low.
The executive standard of P235TR1 steel is EN 10216-1. EN 10025-6 S960QL1 high strength steel, P235TR1 steel is suitable for manufacturing pipes, vessels, equipment, pipe fittings and steel structures. Chemical composition of P235TR1 steel: C ≤ 0.16, Si ≤ 0.35, Mn ≤ 1.2, P ≤ 0.025, S ≤ 0.02, Cr ≤ 0.30, Mo ≤ 0.06, Ni ≤ 0.30, Cu ≤ 0.30, Nb ≤ 0.01, Ti ≤ 0.04, V ≤ 0.02. Chemical composition of P235TR1 steel: tensile strength 360-500 MPa, yield strength ≥ 235 MPa, elongation ≥ 25%. The main steel pipe grades under EN 10216-1 are P195TR1, P195TR2, P235TR1, P235TR2, P265TR1 and P265TR2.
EN 10025-6 S960QL1 high strength steel and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of EN 10025-6 S960QL1 high strength steel and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.
Since its establishment, the company has been deeply supported and loved by customers with its unique business philosophy and business model. The company has always adhered to the tenet of "credibility first, integrity-based, quality first" and sincerely serves new and old customers. At the same time, it keeps pace with the times based on market orientation, continuously expands offline channels, and gradually establishes a complete online E-commerce business management platform. We will always promote our after-sales service to make client satisfied with our goods.
Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our EN 10025-6 S960QL1 high strength steel products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
