Weather resistant steel sheet is a low-alloy high-strength steel that adds a small amount of alloying elements to ordinary steel to make it have good corrosion resistance in the atmosphere. This kind of material has a higher atmospheric corrosion resistance than ordinary carbon steel. A709 grade 50S bridge steel plate, Weather resistant steel sheet and plate is widely used in manufacturing industries such as containers, bridges, automobiles, railway vehicles, and construction abroad.
Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the A709 grade 50S bridge steel plate alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the A709 grade 50S bridge steel plate wear-resistant property to meet the requirements of specific working conditions.
