1-1/4 inch SA709 Gr 50 carbon steel plate sheet stock

The company has allocated special environmental protection facilities for all SA709 Gr 50 carbon steel plate sheet pollution sources, strengthened the recycling of waste resources and improved the efficiency of resource utilization. At present, the recovery and utilization rate of solid wastes such as iron slag, steel slag, iron bearing dust, SA709 Gr 50 carbon steel plate sheet steel mill scale, environmental protection dust has reached 100%.

Bridge steel plates are thick steel plates made of carbon steel and low-alloy steel for bridge construction. The main applications of bridge steel plates are to build railway bridges, highway bridges, and sea-crossing bridges. The bridge steel plates are required to have high strength, durability and bear the load and impact of rolling stock. Bridge steel plates have good water resistance, low thermal conductivity, flat and lubricated surface. The main grades of bridge steel plates are A709 grade 50, A588 grade B, SA709 Gr 50 carbon steel plate sheet and so on.

The cold working performance of SA709 Gr 50 carbon steel plate sheet and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of SA709 Gr 50 carbon steel plate sheet and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.
