YB/T 4137-2005 in English

Scope

This standard specifies the size, shape, weight and allowable deviations, technical requirements, test methods, inspection rules, packaging, marking and quality certificates of high-strength steel plates with low welding crack sensitivity. This standard is applicable to the production of high-strength steel plates with a thickness of 6mm to 100mm that require high weldability, such as pressure steel pipes for hydropower stations, engineering machinery, railway vehicles, bridges, high-rise and long-span buildings. Steel strips can also refer to this standard.
