Carbon steel elbow market situation in carbon steel elbow pipe installation is a common connection with pipe fittings, carbon steel as a material, with the development of the electricity market, carbon steel elbow can be favored by the market and continue to replace some The traditional wear elbow, simply because of its superior product quality and physical and chemical properties. Carbon steel materials classified by purpose can be divided into carbon steel structural steel, carbon tool steel and easy cutting structural steel categories, carbon structural steel building is divided into two kinds of structural steel and steel machinery manufacturing structure; Generally the higher the carbon content of steel in the greater hardness, strength is also higher, but lower ductility. Carbon steel elbow elbow material selection of the material used is carbon steel or high-quality carbon structural steel, these two materials can not only ensure carbon steel elbow with good hardness, strength and wear resistance, but also guarantees plasticity elbow, the elbow will not ensure stress fracture, wounds, etc. during molding. But some special steel piping systems also use elbows, these piping systems for the mechanical properties of the elbow higher, but also difficult to use methods such as forging forming in the process.
