The standard explicitly states that plates shall be delivered in the condition.

: Grade names start with "Q" (for qufu , meaning yield), followed by the minimum yield strength (e.g., Q690) and a quality grade letter (C, D, E, or F) indicating impact testing temperature. gb t 16270 pdf

Unlike regular structural steel, GB/T 16270 steels are (Q+T). The PDF specifies that the steel must be heat-treated after rolling to achieve a martensitic or bainitic microstructure. The standard explicitly states that plates shall be

Q890 and Q960: Ultra-high-strength grades used in specialized lifting gear and high-pressure vessels where weight reduction is vital. Why Professionals Search for the GB/T 16270 PDF The PDF specifies that the steel must be
