When the design imposes special requirements on the steel (such as special refining methods, strict specifications for chemical composition, higher impact energy requirements, increased frequency of mechanical property tests to meet higher standards for non-destructive testing, and specified corrosion test requirements), these should be specified in the design documents. The impact test requirements for steel plates shall be in accordance with the provisions of GB713, GB3531, and GB19189 respectively. If it is necessary to improve the impact energy value, this should be specified in the design documents. For Q245R and Q345R steel plates, if it is required to conduct a shock test at -20°C, this should be specified in the design documents. The impact test requirements for steel forgings shall be in accordance with NB/T47008 and NB/T47009 respectively. If it is necessary to improve the impact energy value, this should be specified in the design documents. For 20, 16Mn, and 20MnMo steel forgings, if it is required to conduct impact tests at -20°C, this shall be specified in the design documents. A. Correct B.
