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 A709 grade 36 bridge 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.
Novel coronavirus pneumonia has been closed in recent years, and Pohang iron and Steel Co., Ltd. closed its overseas processing center in Italy, Malaysia, Philippines and India. At the request of the Italian government, all production activities will be stopped except for the necessary A709 grade 36 bridge steel plate products. POSCO-ITPC, an Italian stainless steel cold rolling mill near Verona in northeast Italy, is scheduled to close from March 26 to April 3.
The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, A709 grade 36 bridge steel plate deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world. The company has won widespread praise from customers.
A709 grade 36 bridge steel plate 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 A709 grade 36 bridge steel plate 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.
