QU Crane rail

High carbon steel U71Mn QU100 national standard crane rail is a steel product commonly used in crane running rails. U71Mn belongs to high carbon steel with a high carbon content, usually between 0.65%-0.77%. The increase in carbon content improves the strength and hardness of the steel, and can withstand the larger load during the operation of the crane. At the same time, the content of manganese is around 1.10%-1.50%. Manganese can enhance the toughness and wear resistance of steel, improve the comprehensive performance of steel, and make it suitable for crane rails that are frequently subjected to impact and friction.

Application areas

Mainly used in the running rails of various types of cranes, such as gantry cranes and bridge cranes in ports, docks, steel mills, mines, railway freight yards and other places. Cranes in these places usually need to frequently lift heavy objects, and have high requirements for the bearing capacity, wear resistance and stability of the rails. U71Mn QU100 national standard crane rails can meet these requirements well and ensure the safe and stable operation of cranes.
