Q550D Q550E H Beam Hlau
【GNEE Group Chaw Ua Haujlwm Ib puag ncig】
GB / T16270 Q550DH-beamhigh-strength structural steel yog ib tug high-strength steel yielded ntawm 550. D yog 0 degrees sawv cev ntawm qhov cuam tshuam tsim nyog. Qhov twg Q550D: Q-steel phaj yield zog ntawm "khoov" thawj tsab ntawv ntawm lo lus hanyu pinyin; 550-yield zog tus nqi, unit MPa; D-zoo qib D (qib muab faib ua C, D, E).
Q550E yog steel H beam high-strength structural steel, feem ntau xa hauv thermomechanical tswj dov lub xeev, kuj tuaj yeem xa tuaj rau hauv tempered (quenched + tempered) lub xeev raws li qhov xav tau, nrog lub zog siab, zoo toughness, zoo heev low-temperature toughness, zoo. kev ua tau zoo thiab vuam kev ua tau zoo, hnav-tiv taus, corrosion-resistant thiab lwm yam ntxwv.
