Cov ntsia hlau siab carbon muaj kev tiv thaiv kev laus, tiv thaiv kev hloov pauv sai sai, tiv thaiv corrosion, txias thiab kub tsis kam, muaj peev xwm muaj peev xwm, siab siab, zoo tensile zog; tsis yooj yim deformed tom qab loading, noo noo-pov thawj, kev co mitigation, suab nrov absorbing thiab zoo rwb thaiv tsev. Yooj yim rau nruab, hammering tuaj yeem ua tiav, tsis muaj cov cuab yeej tshwj xeeb uas xav tau.
Cov hlau uas nyiam tshaj yog quenched thiab hardened, zoo nkauj thiab xeb resistant, nrog siab hardness thiab zoo toughness.
High hardness thiab tensile lub zog rau hnav thiab tsim kua muag.
Convex qauv ntawm tus ntsia thawv lub cev rau kev sib txhuam ntau dua, kev siv zog tsawg dua thiab nrawm dua.
Hardened rau zoo nkag mus thiab tsawg deformation.
