Thaum peb nrum cov hlau grey, peb nruj ua raws cov tshuaj lom neeg thiab cov khoom siv kho tshuab raws li cov stardards lossis qhov yuav tsum tau los ntawm cov neeg siv khoom. Dhau li, peb muaj lub peev xwm thiab cov khoom siv coj los ntsuas yog tias muaj casting cuam tshuam sab hauvgrey hlau xuab zeb castings.
Lub taub lim dej uas muaj cov pa roj carbon ntau dua 2% yog hu ua cov nplaim dej tsis haum. Txawm hais tias cov cam khwb cia muaj peev xwm muaj cov pa roj carbon feem pua ntawm 2 txog 6.67, cov kev coj ua tau txwv ib txwm nyob ntawm 2 txog 4%. Cov no yog qhov tseem ceeb vim lawv qhov kev ua tau zoo casting.
Grey hlau castings yog qhov pheej yig tshaj li cov hlau ductile, tab sis nws muaj ntau yam qis dua lub zog thiab ductility dua li hlau ductile. Cov hlau grey tsis tuaj yeem hloov cov pa roj carbon steel, thaum lub zas hlau ntog tuaj yeem hloov cov pa roj carbon hlau nyob rau qee qhov xwm txheej vim lub zog loj, cov khoom muaj zog thiab elongation ntawm hlau ductile.
Los ntawm cov hlau-carbon equilibrium daim duab, nws tuaj yeem pom tau tias cov cam khwb cia muaj qhov tseem ceeb cementite thiab ferrite. Vim tias qhov feem pua ntawm cov pa roj carbon ntau, qhov nyiaj ntawm cov cementite yog qhov txiaj ntsig uas ua rau muaj qhov nyuaj thiab ua kom zoo nkauj rau cov hlau cam.
