On the basis of carbon steel, a certain amount of alloying elements are added to achieve the required performance requirements, that is alloy structural steel. The main features of alloy structural steel are high strength, good toughness, plasticity and weldability, and are widely used in pressure vessels, construction machinery, petrochemicals, bridges, shipbuilding, construction and other steel structures.
