GB/T 16270 is the Chinese national standard for high-strength structural steel plates specifically delivered in a quenched and tempered state. Whether you're sourcing for bridge construction or heavy machinery, this standard dictates the chemical composition, mechanical properties, and testing methods required for these materials. Key Highlights:
It defines requirements for tensile strength, elongation, and impact energy (Charpy V-notch test) even at low temperatures, such as -40°C or -60°C for specific grades. gb t 16270 pdf

This standard is a critical specification in the Chinese steel industry, widely used in construction, bridge building, and heavy machinery.
. It covers plates used in heavy machinery, mining equipment (e.g., excavators, loaders, bulldozers), and structural parts of cranes. Delivery Condition : Steel must be supplied in a quenched and tempered condition (often referred to as slack quenching). Steel Grades : Common grades include Q460, Q500, Q550, Q620, Q690, Q800, Q890, and Q960 Quality Designations
