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.
It has good toughness. By strictly controlling the chemical composition, reducing the content of SA572 Grade 50, Q345C, SM570 low alloy harmful elements and selecting reasonable heat treatment conditions, NM360 steel plate has good toughness. Therefore, the highly reliable structural parts can be constructed according to the brittle failure of wear-resistant components. Uniform and beautiful quality, SA572 Grade 50, Q345C, SM570 low alloy using advanced technology and equipment, combined with high and scientific technical management, the material and shape of the product are even and consistent.
We have transportation department and shipping department to coordinate logistics and delivery. Seamless connection between inland transportation and sea transportation ensures smooth delivery, saves transportation time and delivers goods in the first time. During the sea transportation, we will update the freight progress for customers on a regular basis, so as to facilitate the tracking of customers and make preparations for receiving goods leisurely and timely.
The pre cooling direct quenching and low temperature tempering of wear-resistant composite plate can reduce the quenching deformation of the workpiece, and the residual austenite content in the carburized layer can also be slightly reduced. The surface hardness of the hardfacing wear-resistant composite plate, SA572 Grade 50, Q345C, SM570 low alloy is slightly increased, but the austenite grain does not change. It is widely used in various tools of fine grain steel manufacturing.
