S690 QL
S690 QL is a high strength steel grade. The letter “S” is a standard designation for structural steels and the number “690” refers to the minimum yield strength of the steel (690 MPa). “QL” stands for “high ductility”. This steel grade has high strength, good impact resistance and good weldability.
Some Frequent Uses of the S690QL:
- Construction and Structures: Used in high-rise buildings, bridges, viaducts, tunnel lines, wind turbines and other structural components. The high strength of S690 QL makes structures lighter and stronger.
- Heavy Machinery and Equipment: Used in cranes, construction machinery, mining equipment, excavators, crushers, lifting equipment and other heavy machinery. The high strength of S690 QL helps such equipment to carry heavy loads and withstand harsh working conditions.
- Marine and Shipbuilding: It is used to strengthen steel plates used in shipbuilding and to reinforce structural components. S690 QL provides resistance to seawater and corrosive environments.
- Mining and Energy Sector: Used in applications such as mining machinery, mine shafts, pipelines, oil and gas equipment. S690 QL provides durability in corrosive environments and high stress conditions.
- Vehicles: Used in heavy-duty trucks, tankers and railroad vehicles. The lightweight construction of S690 QL makes vehicles more efficient.
