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.

The service temperature of high pressure seamless steel pipe is below 450 ℃, and the domestic pipes are mainly made of HARDOX 400 properties, No.10 and No.20 carbon steel hot-rolled pipes or cold drawn pipes. High pressure seamless steel pipe is often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and water vapor, the pipe will be oxidized and corroded. The steel pipe is required to have high endurance strength, high oxidation resistance and corrosion resistance, and good structure stability.

GB standard wear resistant steel plates parameters: The standard for Chinese wear plates is GB/T 24186, which includes NM400, NM450, NM500, NM550, NM600 etc. steel grades. According to the standard, the NM400 plate thickness is no more than 80mm, and hardness is 370-430HBW. HARDOX 400 properties, NM450 plate thickness is no more than 80mm, and hardness is 420-480HBW. NM500 plate thickness is no more than 70mm, and hardness is 470HBW min. And NM600 plate thickness is no more than 60mm, and hardness is 570HBW min.

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This HARDOX 400 properties alloy steel HARDOX 400 properties still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.
