GB Q370R GB 713 Phaj
nkoj steel phaj Khoom Taw qhia
GB Q370R GB 713 steel yog ib qho ntawm cov khoom siv dav siv hauv cov boilers niaj hnub no. Tsim los ntawm Suav engineers nyob rau hauv 1890s, cov hlau yog ib qho kev sib xyaw ntawm ntau yam khoom tsim los ua kom muaj txiaj ntsig zoo thiab ua haujlwm ntev, ua rau nws tseem ceeb hauv kev lag luam niaj hnub no. Thaum lub ntiaj teb boiler steel kev lag luam tab tom ntsib cov teeb meem nce ntxiv xws li nce nqi raw khoom thiab tsis muaj kev txawj ntse, kev txhim kho tshiab hauv kev lag luam tau pab daws cov teeb meem no, ua kom ntseeg tau tias GB Q370R GB 713 tseem yog cov khoom tseem ceeb rau xyoo tom ntej.
