specifies the technical requirements for high strength structural steel plates .

: Includes tensile strength, elongation, and Charpy pendulum impact testing. For instance, Q690E is a low-temperature grade tested for impact at -40°C. gb t 16270 pdf

According to the English version of GB/T 16270-2009 , the standard outlines several critical parameters: According to the English version of GB/T 16270-2009

GB/T 16270 standard is a Chinese national technical specification for high-strength structural steel plates delivered in a quenched and tempered condition. It is primarily used in heavy industry to ensure materials can withstand extreme mechanical stress and low temperatures. Chinese Standard GB/T Core Story of the Standard Purpose & Development Note: The suffix letters (D, E) denote impact

This process allows for the production of plates with an excellent strength-to-weight ratio, crucial for reducing structural weight in mobile equipment like cranes and trucks.

Note: The suffix letters (D, E) denote impact test temperatures: D = -20°C, E = -40°C.
