On Jan. 31, 2019, BBN steel held the annual meeting with all employees, family members, and friends. It is a moment of joyand it is a moment to summarize the past and look forward.Looking back on 2018, BBN steel exported a573 grade 70 high strength carbon steel more than 2 million tons of steel materials to all parts of the world and made outstanding contributions to infrastructure construction at home and abroad. In 2019, BBN steel will make persistent efforts and forge ahead.
15CrMo steel belongs to Pearlite Heat-resistant steel, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperature (generally not more than 600 ℃), and has certain hydrogen corrosion resistance. So a573 grade 70 high strength carbon steel, 15CrMo steel is widely used in petrochemical industry. However, due to the high content of Cr, C and other alloy elements in the steel, the hardening tendency of 15CrMo steel is obvious and the weldability is poor. The main problems are hardening in heat affected zone, cold cracks and reheat cracks during post weld heat treatment.
Our company is located in the Central Plains, Zhengzhou City, convenient transportation. There is the largest Xinzheng airport, welcome customers from all over the world to visit our company. Our factories are all located near the port. The logistics is very convenient, which can save the delivery time.
LNG ships are called "super-refrigerated vehicles on the sea", and their service environment is at a very low temperature of minus 163 degrees Celsius. This requires that the steel for LNG storage tanks must have low temperature resistance, often using Invar steel or 9Ni steel. At present, a complete series of nickel steels such as 0.5Ni steel, 2.5Ni steel, 3.5Ni steel, 5Ni steel, and 9Ni steel have been formed in the field of low-temperature steel. China has also developed relatively mature 3.5Ni steel and 5Ni steel. And 9Ni steel, and successfully used in the construction of low-temperature transport ships.
Our company has its own steel plate manufacturing plant, processing plant and steel pipe plant. We can machine the steel according to the a573 grade 70 high strength carbon steel customer's requirements and meet the customer's requirements. If you want to ask any questions about steel products, please contact us directly. Our customer service staff will give you a detailed answer. If you want to purchase a573 grade 70 high strength carbon steel steel products, please tell me your specific needs, we have professional business personnel to communicate with you.
