1. Dab tsi yog cov cuab yeej tseem ceeb siv los txheeb xyuas cov qib carbon steel yeeb nkab?
Cov khoom tseem ceeb yogTensile zog(kev ntxhov siab ntau tshaj),Yield zog(kev ntxhov siab uas nws pib deform plastically), thiabElongation(kev ntsuas ntawm ductility) -3-6.
2. Vim li cas carbon hlau thiaj li raug corrosion?
Cov pa roj carbon steel lub ntsiab yog hlau, uas yog thermodynamically inclined rau revert mus rau nws oxide daim ntawv (xeb) nyob rau hauv lub xub ntiag ntawm oxygen thiab noo noo. Nws tsis muaj cov ntsiab lus tseem ceeb xws li chromium uas tsim cov txheej txheem tiv thaiv passive -4.
3. Qhov kub thiab txias cuam tshuam li cas rau kev ua haujlwm ntawm cov pa roj carbon steel kav?
Ntawmkub kub, carbon hlau tuaj yeem poob lub zog thiab ua rau muaj kev nkag mus thiab oxidation. Ntawmqhov kub thiab txias, nws tuaj yeem poob ductility thiab ua nkig, ua rau muaj peev xwm tawg. Cov qib tshwj xeeb zoo li cov hauv ASTM A333 yog siv rau qis- qhov kev pabcuam kub -3-5.
4. thermal expansion yog dab tsi thiab vim li cas nws thiaj li muaj kev txhawj xeeb hauv cov kav dej?
Thermal expansion yog qhov nyiam ntawm cov khoom siv yeeb nkab kom nce ntim thaum kub nce. Yog tias qhov kev nthuav dav no txwv tsis pub, nws tuaj yeem ua rau muaj kev ntxhov siab loj ntawm cov yeeb nkab, fittings, thiab kev txhawb nqa, ua rau cov xau, buckling, lossis cov khoom tsis ua haujlwm -8.
5. Dab tsi yog qhov chaw siv rau cov pa roj carbon steel kav?
Lawv tau siv dav hauv kev lag luam roj thiab roj (kev sib kis thiab kev ua kom zoo), petrochemical cov nroj tsuag, lub zog tsim hluav taws xob (boilers thiab chav kab), kev tsim kho (kev txhawb nqa), kev xa dej, thiab kev tsim cov tshuab -2-9.
