8. nquag nug cov lus nug

Q: Dab tsi yog qhov txawv ntawm cov hlau ntshiab thiab cov hlau roj carbon tsawg?
A: Cov hlau ntshiab muaj<0.025% carbon vs. 0.05-0.25% in low-carbon steel, resulting in superior ductility and magnetic permeability.

 

Q: Kev ntsuas kev ntsuas li cas?
A: Cov hau kev niaj hnub no suav nrog kev sib txuas lus ntshav ntshav (icp) spectroscopy thiab kev txiav txim siab rau cov pa roj carbon / sulfur txiav txim .

 

Q: Cov hlau ntshiab tuaj yeem kho cov cua sov?
A: Yog, tab sis nws cov roj carbon tsawg cov ntsiab lus txwv nyuaj .}} {{1}.
