ASTM A1011 HSLAS-F Qib 50 ASTM A1011 / A1011M Tshuaj Element
ASTM A1011 HSLAS-F Qib 50 ASTM A1011 / A1011M ntxiv rau cov pa roj carbon, hlau kuj tseem muaj ib qho me me ntawm manganese (Mn), silicon (Si), sulfur (S), phosphorus (P), oxygen (O), nitrogen ( N) thiab hydrogen (H). Cov ntsiab lus no tsis txhob txwm ntxiv los txhim kho qhov zoo ntawm cov hlau, tab sis yog coj los ntawm ore thiab smelting txheej txheem, yog li lawv hu ua impurity ntsiab. Cov impurities no muaj qee yam cuam tshuam rau cov khoom ntawm cov hlau. Txhawm rau kom ntseeg tau qhov zoo ntawm cov hlau, cov tshuaj muaj pes tsawg leeg ntawm txhua yam hlau yog nruj me ntsis raws li cov qauv kev.
