The characteristics and scope of application of A709 Gr HPS50W bridge steel plate, No. 55 steel: 55# steel is a high-strength medium-carbon steel with high surface hardness and strength after treatment, but poor plasticity and toughness, medium cutting performance, poor weldability and hardenability, and water quenching has the tendency to form cracks. 55# steel is generally used after normalizing or quenching.
The company adheres to the "variety, quality and efficiency" road. We have established a technology center, a brand cultivation management system and a quality control system. Now the company has formed an independent innovation system integrating A709 Gr HPS50W bridge steel plate production, learning, research and marketing. Our company has passed ISO9001 quality management system certification and ISO10012 measurement management system certification.
A709 Gr HPS50W 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 Gr HPS50W 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.
