Taw qhia ntawm cov carbon hlau tsawg
Cov tawv me me yog cov xeb hlau uas muaj cov pa roj carbon tsawg dua 0.25%. Nws tseem hu ua hlau tsis khov vim tias nws tsis tshua muaj zog, tsis muaj tawv thiab muag muag. Nws suav nrog feem ntau ntawm cov pa roj carbon zoo tib yam txheej txheem steel thiab ib feem ntawm cov pa roj carbon zoo tsim cov hlau, feem ntau tsis kho cua sov rau cov txheej txheem kev hloov kho engineering, thiab qee qhov raug carburized thiab lwm qhov kev kho cua sov rau cov tshuab kho tshuab uas xav tau hnav tsis kam.
Qhov tsawg carbon steel annealed qauv yog ferrite thiab me me ntawm pearlite, uas muaj lub zog tsis tshua muaj zog thiab tawv, thiab zoo plasticity thiab toughness. Yog li no, cov qauv txias ua tau zoo, thiab txias tsim tau tuaj yeem ua los ntawm cov qauv xws li crimping, khoov, lossis nias. Cov hlau no tseem muaj weldability zoo. Cov pa roj carbon ntau uas muaj cov pa roj carbon ntau nyob ntawm 0.10% mus rau 0.30% tau yooj yim txais rau ntau yam txheej txheem xws li forging, vuam thiab txiav, thiab feem ntau yog siv hauv kev tsim cov txuas, rivets, bolts, shafts, thiab lwm yam.
