High strength Q500CFC Q500CFD Q500CFE steel plates with low welding crack sensitivity

Q500CF steel has three grades: Q500CFC, Q500CFD and Q500CFE. The grades of high-strength steel plates with low welding crack sensitivity: Q460CFC, Q460CFD, Q460CFE, Q500CFC, Q500CFD, Q500CFE, Q550CFC, Q550CFD, Q550CFE, Q620CFC, Q620CFE, Q690CFC, Q690CFE, Q800CFC, Q800CFD, Q800CFE. Where, Q represents the minimum specified yield strength, CF is the international letter representing low weld crack sensitivity, which is the abbreviation of crack free, and C, D, E are quality grades.

Q500CFC, Q500CFD, Q500CFE high-strength steel plates with low welding crack sensitivity are mainly used to make penstocks for hydropower stations, engineering machinery, railway vehicles, bridges, high-rise and long-span buildings with high requirements for weldability.
