Qhov sib txawv thiab cov ntawv thov ntawm cov hlau thiab hlau hlau

Lub ntsiab sib txawv ntawm cov roj carbon hlau thiab hlau sib txawv yog qhov sib txawv hauv cov ntsiab lus lawv muaj. Carbon Steel yog tsuas yog tsim cov hlau thiab carbon, thaum alloy steel, thaum chemical, thiab chromium, uas muab alloy steel zoo dua thiab corrosion tsis zoo. Yog li ntawd, alloy steel yog qhov tsim nyog dua hauv cov ntawv thov uas yuav tsum muaj zog thiab corrosion tsis kam.
