The GB/T 16270 standard specifies the technical requirements for hot-rolled steel plates with high yield strength. These steels undergo a specific heat treatment process—quenching and tempering (Q&T)—to achieve a superior balance of hardness, toughness, and strength. Key features of this standard include:
To comply with GB/T 16270, steel manufacturers must adhere to strict chemical composition limits and mechanical property thresholds. gb t 16270 pdf
Grades: Includes high-strength grades like Q460, Q500, Q550, Q620, Q690, Q800, Q890, and Q960.
