Cov Khoom Siv: Cov yam ntxwv tseem ceeb
253ma(Undu s30815) sib txuas zoo heev kub-zog nrog oxidation tsis kam. Qhov no ua rau nws zoo tagnrho rau cov ntawv thov hauv cov chaw ib puag ncig heev, xws li cov cub tawg thiab cov kev sib pauv hluav taws xob. Cov khoom siv muaj lub siab chromium thiab cov ntsiab lus tsib xee, muab cov ntsiab lus tsis zoo, muab cov txiaj ntsig zoo tshaj plaws rau oxidation ntawm qhov kub thiab txias txog li 1150 ° C (2100 ° F).
