GB/T 16270 focuses primarily on steel in the delivery state. Quenching hardens the steel, while tempering restores toughness, ensuring the final plate is both incredibly hard and ductile enough to resist catastrophic brittle fractures. Global Equivalents to GB/T 16270
The letters following the number represent the quality grade, which primarily relates to the impact toughness requirements at different temperatures. For example, “C” typically specifies impact testing at 0°C, “D” at -20°C, “E” at -40°C, and “F” at -60°C .
