BBN company has implemented a resource strategy combining global resource procurement, domestic resource unified purchase, and joint purchase and distribution. It has maintained good relations of cooperation with more than 100 domestic and foreign steel mills, and can purchase low-quality and high-quality steel futures in all directions and through multiple channels. The company can grasp the specifications and quantities of the spot resources of major steel mills in real time, and can timely and quickly meet customer demand for steel spot resources.
45# steel is a common medium carbon quenched and tempered structural steel. The cold plasticity of 45# steel is general. Annealing and normalizing are slightly better than ASTM A588 structural steel plate quenching and tempering. 45# steel has higher strength and better machinability. After proper heat treatment, 45# steel can obtain certain toughness, plasticity and wear resistance. 45# steel is suitable for hydrogen welding and argon arc welding, not suitable for gas welding.
Global ASTM A588 structural steel plate crude steel production in March this year increased by 2.6 percent month on month and fell by six percent year on year to 147.1 million metric tons. accordina to the World Steel Association (worldsteel).In the first quarter of this year, global ASTM A588 structural steel plate crude steel production decreased to 443.03 million mt, down 1.4 percent year on year.
