GB/T700 Q235D steel is carbon steel mainly used for building steel structural.The best equivalent steel grade is Grade S235J0 under steel specification EN 10025-2. GB/T700 Q235D steel shall be done low temperature impacting test under minus 20 centigrade. Normally As-rolled and Control-rolled is ok for rolling Q235D, normalized is suggested when the steel plates are heavy thickness.
Standard: GB/T700
Main grades: Q235A, q235b, Q235C, Q235D, Q275
