Q370R cov hlau tsis tshua muaj hlau
Q370R siab zog phaj yog ib qho tsis tshua muaj alloy siab zog steel phaj uas nws cov khoom ua raws li Suav tus qauv GB713.
Q370R siab zog ntawv hlau muaj qhov zoo vuam kev ua tau zoo, siab tsis kam thiab kev nyuaj siab corrosion cracking kuj. Cov ntsiab lus tsis tshua muaj carbon nyob rau hauv nws cov tshuaj muaj pes tsawg leeg muaj txiaj ntsig zoo rau kev ntseeg siab thiab tawv ntawm cov pob qij txha, thaum tsim nyog manganese thiab silicon cov ntsiab lus tuaj yeem txhim kho lub zog thiab plasticity ntawm steel daim hlau.
Q370R lub zog muaj zog cov qauv hlau muaj qhov ua tau zoo ntawm qhov kub thiab txias, kev ua haujlwm siab thiab corrosion kuj, thiab yog siv dav hauv kev tsim cov hlab ntsha siab, boilers thiab lwm yam khoom siv.
