Steel is an alloy of iron with carbon, silicon, manganese, phosphorus, sulfur and a small amount of other elements. In addition to iron, carbon content plays an important role in the mechanical properties of SA514 Gr Q steel material and so on steel. Iron and steel is an important raw material for machinery, construction, hardware and other industries. As an important pillar industry, the development of iron and steel has a glorious period, in which Tangshan was once an important production base of China's iron and steel. This is closely related to its geographical location and energy advantages.
