: Specifies strict limits for chemical composition, mechanical properties (yield/tensile strength, elongation), and impact toughness at specific temperatures (e.g., Q690E requires impact testing at -40°C ) .

Steel is tested for yield strength, tensile strength, elongation, and impact energy. For example, must maintain specific impact toughness at Chinese Standard GB/T Common Steel Grades

: Many public libraries, especially those with a focus on engineering or technology, offer access to standards databases, which might include Chinese national standards.
