Difference Between High Construction Steel And Ordinary Steel

My country is a heavy industry country, and the iron and steel industry occupies a large proportion of heavy industry. With the development of science and technology, steel materials with different properties have been developed and put into construction. In recent years, the steel favored by the construction industry is high-grade steel, so what is the difference between high-grade steel and ordinary steel? For everyone to popularize science.
Ordinary steel plates have too many impurities and can be used to build houses and ships. However, with the development of the steel industry, the market demand for steel is increasing. Especially when building high-rise buildings, considering the load-bearing structure and safety, ordinary steel cannot meet the requirements, so high-rise steel has emerged as the times require. The requirements for high-grade steel are very high. Compared with ordinary carbon or low-alloy steel plates, the yield strength of Gaojian steel plates is set to an upper limit, and the tensile strength is increased, requiring the ratio of carbon equivalent to yield strength. It has low yield ratio, sufficient tensile strength and good shock resistance. Steel plates are required to have a certain level of lamellar tear resistance for added safety. It needs to have high plasticity and toughness, so that the steel plate has good mechanical properties. It has better welding performance than ordinary steel, thereby reducing labor intensity and improving labor efficiency. Can provide CNC flame cutting, plasma cutting, laser cutting, fully automatic CNC cutting, water cutting, steel plate shot blasting and sandblasting. CNC cutting can be carried out according to the requirements of the workpiece required by the customer and programmed according to the drawings. Available steel plate specification range: thickness 8-650mm, width 1500-4020mm, length 3000-18000mm, single weight up to 30 tons.
