Bridge steel sa573 gr.65 high strength structural steel is required to have higher strength, toughness, load and impact of rolling stock, and good fatigue resistance, low temperature toughness and atmospheric corrosion resistance. With the development of domestic railway construction towards high speed and heavy load, railway bridge steel developing in the direction of high speed, heavy load, long span, beautiful and novel structure, and full welding, higher requirements are imposed on the properties of steel for bridges. In particular, the development of cross-sea bridges has put forward higher requirements on the corrosion resistance of steel for bridges.

The company has huge steel sa573 gr.65 high strength structural steel products stock all the year round to meet the urgent needs of customers. For stock products, we can arrange delivery within 3 days. The transportation department and shipping department shall coordinate and follow up to update the progress to customers regularly, i.e. where the goods have arrived, so as to let customers not worry and rest assured. Think about what the customers think and what the customers are anxious about, solve problems for customers efficiently and effectively, is the direction of our unremitting efforts.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than sa573 gr.65 high strength structural steel. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel sa573 gr.65 high strength structural steel is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
