General Information for Steel
Hlau, hlau alloy ntawm hlau thiab carbon nyob rau hauv uas cov ntsiab lus ntawm cov pa roj carbon ntau txog li 2 feem pua (nrog rau cov ntsiab lus carbon ntau dua, cov khoom siv txhais tau tias yog cam khwb cia hlau). Txog tam sim no cov khoom siv dav siv ntau tshaj plaws rau kev tsim lub ntiaj teb kev tsim kho vaj tse thiab kev lag luam, nws yog siv los tsim txhua yam los ntawm xaws koob mus rau cov roj tankers. Tsis tas li ntawd, cov cuab yeej xav tau los tsim thiab tsim cov khoom zoo li no kuj yog ua los ntawm cov hlau. Raws li qhov qhia txog qhov tseem ceeb ntawm cov khoom siv no, iThe lub ntsiab yog vim li cas rau qhov nrov ntawm cov hlau yog tus nqi qis ntawm kev tsim, tsim, thiab ua nws, qhov abundance ntawm nws ob raw khoom (hlau ore thiab seem), thiab nws unparalleled. ntau yam ntawm mechanical zog.
