In 1045 steel plate, the ‘10’ means a basic carbon steel and ‘45’ designates the approximate carbon content. 1045 steel is included in the ASTM 830 (A830) family of specifications. A830 Grade 1045 hot rolled steel plate can be cut to various shapes, hammer forged and heat treated. 1A709 Gr 50S bridge steel plate product is mostly used where greater strength is required than lower carbon steels. Welcome to contact us for hot rolled plates stock price.
At the same time of doing well in A709 Gr 50S bridge steel plate production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the A709 Gr 50S bridge steel plate technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
Quenching Improve the hardness of A709 Gr 50S bridge steel plate steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of A709 Gr 50S bridge steel plate steel and comprehensive mechanical properties.
A709 Gr 50S bridge steel plate, Hot rolled seamless tube is usually produced on automatic tube rolling mill. After the solid tube blank is inspected and the surface defects are removed, it is cut to the required length, centered on the end face of the piercing end of the tube blank, then sent to the heating furnace for heating, and perforated on the piercing machine.
