Q550D Q550E H Beam Iron
【GNEE Group Office Environment】
GB/T16270 Q550D H-beam high-strength structural steel is a high-strength steel yielded at 550. D is 0 degrees on behalf of the impact qualified. Which Q550D: Q-steel plate yield strength of the "bend" the first letter of the word hanyu pinyin; 550-yield strength value, unit MPa; D-quality grade D (grade is divided into C, D, E level).
Q550E is steel H beam high-strength structural steel, mainly delivered in thermomechanical controlled rolling state, can also be delivered in tempered (quenched + tempered) state according to the demand, with high strength, good toughness, excellent low-temperature toughness, good processing performance and welding performance, wear-resistant, corrosion-resistant and other characteristics.
