Cov khoom siv ntawm cov chemical hlau nruas

Cov hlau drums yog cov hlau feem ntau. Piv nrog rau lwm cov hlau, hlau peev txheej muaj nqi ntau dua, kev siv lub zog thiab cov nqi qis dua, thiab nws tseem suav rau thawj qhov chaw ntawm cov hlau. Ntim steel yog tsuas yog qis-carbon nyias steel phaj. Qes-carbon nyias steel phaj muaj plasticity zoo thiab ductility, zoo ua-ua processability, thiab zoo heev tiv thaiv kev ua tau zoo. Cov hlau nruas muaj ntau yam khoom siv, thiab kev siv hluav taws xob thiab cov nqi qis dua. Lub nruas hlau muaj qhov tshwj xeeb nws yog xim hlau thiab kuj yog qhov yooj yim luam tawm thiab dai kom zoo nkauj, yog li ntawd cov tsos ntawm cov khoom tuaj yeem ua khoom kim, zoo nkauj thiab lag luam.
