Product Introduction
GB QU crane rail is a kind of rail commonly used for crane operation, and the grades of U71Mn and U75V are often used. U71Mn has a high manganese content, which can improve the strength and hardness of steel, as well as the toughness and wear resistance of steel. U75V has a carbon content of about 0.75% and contains vanadium. The addition of vanadium can refine the grains and improve the strength, toughness and wear resistance of steel.
Hot rolling process is often used in the production process, which can improve the internal structure of steel, make its grains denser and more uniform, thereby improving the strength and toughness of the rail and enhancing its fatigue resistance.
