Cov pa roj carbon steel feem ntau yog hais txog cov hlau uas nws cov khoom siv kho tshuab nyob ntawm cov ntsiab lus carbon hauv cov hlau. Feem ntau, tsis muaj ntau cov ntsiab lus alloying ntxiv. Txawm li cas los xij, ntxiv rau cov pa roj carbon monoxide, carbon hlau tseem muaj me me ntawm silicon, manganese, sulfur, phosphorus thiab lwm yam khoom. Feem ntau, qhov siab dua cov ntsiab lus ntawm carbon steel, qhov hardness thiab lub zog ntau dua, tab sis cov yas qis dua. Cov pa roj carbon steel qee zaum kuj hu ua cov pa roj carbon zoo tib yam lossis carbon hlau. Nws feem ntau yog xim dub-grey hauv qhov tsos, thiab qhov roughness ntawm qhov chaw txawv nyob ntawm cov txheej txheem tsim khoom.
Cov yam ntxwv ntawm carbon steel yeeb nkab
- Lub zog siab: Txij li cov yeeb nkab steel muaj cov pa roj carbon ntau dua, nws muaj zog dua thiab muaj zog dua.
- Cov thermal conductivity zoo: Nws tuaj yeem tiv taus qhov kub thiab txias, thiab tsim nyog rau kev xa cov kua kub xws li roj lossis chav.
- Muaj zog corrosion kuj: Nws tuaj yeem siv rau sab nraum zoov hnyav yam tsis muaj kev txhawj xeeb txog xeb lossis hnav sai
- Qhov kub thiab txias tsis kam: Nws yuav tsis ua nkig los yog tawg thaum raug kub, yog li cov pa roj carbon steel kav yog qhov tsim nyog rau cov nroj tsuag hluav taws xob thiab lwm qhov chaw muaj kev cuam tshuam los ntawm tshav kub.
- Kev ua haujlwm zoo: Cov pa roj carbon steel kav tau yooj yim ua tiav los ntawm kev txiav, khoov, khoov, vuam thiab lwm yam txheej txheem ntawm tus nqi qis.
Raws li kev sib xyaw thiab kev siv thev naus laus zis ntawm carbon steel kav, carbon steel kav tuaj yeem muab faib ua cov hauv qab no:
1. Seamless carbon steel yeeb nkab: Seamless carbon steel yeeb nkab yog cov yeeb nkab ua los ntawm tag nrho cov pa roj carbon steel los ntawm kub dov los yog txias txias. Vim muaj cov txheej txheem tsim khoom sib txawv, nws tau muab faib ua kub dov (extruded) seamless steel yeeb nkab thiab txias-draw (dov) seamless steel yeeb nkab. Cold-drawn (dov) cov kav dej tau muab faib ua cov kav dej thiab cov kav dej tshwj xeeb.
2. Welded carbon steel yeeb nkab: Welded carbon steel yeeb nkab yog cov yeeb nkab ua los ntawm vuam carbon steel phaj rau hauv cov kav dej siv vuam tshuab. Nws lub zog thiab corrosion kuj yog me ntsis qis dua cov seamless carbon steel kav.
3. Alloy carbon steel yeeb nkab: Alloy carbon steel yeeb nkab yog cov pa roj carbon steel yeeb nkab nrog qee cov ntsiab lus alloy ntxiv rau nws los txhim kho nws lub zog thiab corrosion kuj.
