The standard covers several essential areas for ensuring the quality and performance of structural steel:

Tell me which detail matters most, and I can pull that specific data for you.

: The official website for Chinese national standards is www.gbstandards.org or you can check the Standardization Administration of China (SAC) website. Sometimes, these standards are available for purchase or download directly.

: It specifies inspection rules, including ultrasonic testing (referenced in GB/T 2970) and Charpy V-Notch impact tests.

Impact Toughness: V-notch impact testing ensures the steel remains ductile at low temperatures (e.g., -20°C, -40°C, or -60°C).

This standard specifies the classification, code, dimension, shape, weight, technical requirements, test methods, inspection rules, packaging, marking, and quality certificates for high-strength structural steel plates and strips.
