Low alloy high strength steel plate has the advantages of good welding performance, cold and hot pressure processing performance and corrosion resistance, high strength, good comprehensive performance, long service life, wide application range, and more economical.It is widely used in Bridges, ships, boilers, vehicles and important building structures.
Low alloy high strength structural steel is made by adding a small amount of alloying elements on the basis of carbon structural steel (Wc=0.16%~0.2%), which has good welding performance, plasticity, toughness and processing properties, good corrosion resistance, higher strength and lower critical transition temperature of cold and brittle. Its designation method is basically the same as that of carbon structural steel. It is suitable for building Bridges, ships, vehicles, railways, high pressure vessels, boilers, automobiles, tractors, large steel structures and large military projects
