Q420GJC Q420GJD H Hlau Beam

 

 

Q420GJC h zoo li tus hlau beam thiab Q420GJD h zoo li tus steel beam yog lub siab -nce tsev steel, tsab ntawv "Q" yog steel yield zog ntawm "yield" lo lus, 420 yog lub yield point ntawm steel; Tsab ntawv "GJ" yog lub ntsiab lus ntawm hanyu pinyin rau siab -nce tsev; C thiab D yog cov cim ntawm qib steel zoo.

 

Q420GJC steel h profile yog siv rau hauv kev tsim cov khoom siab- nce siab, thaj chaw thaj chaw, cov qauv loj - ncua thiab lwm yam tseem ceeb hauv tsev.

 

Q420GJD h zoo li hlau yam ntxwv thiab daim ntawv thov cheeb tsam: siab zog, zoo qaug zog kuj; siab toughness thiab tsawg brittle hloov kub; zoo txias forming zog thiab vuam zog; nrog zoo corrosion kuj thiab ib co℃ntawm hnav kuj. Lub zog siab, tshwj xeeb tshaj yog nyob rau hauv lub normalized los yog normalized thiab tempered lub xeev muaj kev zoo txhua yam khoom.
