    A. Ntxiv rau Q345A thiab Q345B Qib, cov hlau yuav tsum muaj tsawg kawg yog ib qho ntawm cov khoom siv nplej uas tau ua kom zoo Al, Nb, V, thiab Ti. Raws li qhov xav tau, tus neeg muag khoom tuaj yeem ntxiv ib lossis ntau cov khoom siv nplej uas tau ua kom zoo. Tus nqi siab tshaj plaws yuav tsum yog raws li tau teev tseg hauv lub rooj. Thaum muab ua ke, Nb + V + Ti tsis pub ntau tshaj 0.22% B. Rau Q345, Q390, Q420 thiab Q46O Qib, Mo + Cr tsis pub ntau tshaj 0.30% C. Thaum Cr thiab Ni ntawm txhua qib siv ua cov khoom seem, cov ntsiab lus ntawm Cr thiab Ni yuav tsum tsis pub ntau tshaj 0.30%; Thaum nws tsim nyog ntxiv, cov ntsiab lus yuav tsum ua tau raws li qhov yuav tsum tau ua hauv lub rooj lossis txiav txim siab los ntawm tus neeg muag khoom thiab tus neeg yuav khoom los ntawm kev sab laj. D. Yog tias tus neeg muag khoom tuaj yeem ua kom ntseeg tau tias cov ntsiab lus nitrogen ua tau raws li qhov yuav tsum tau ua hauv lub rooj, kev tshuaj xyuas cov ntsiab lus nitrogen yuav tsis ua tau. Yog tias Al, Nb, V, Ti Thiab Lwm Cov Khoom Siv Alloy Uas Muaj Nitrogen Fixation Ntxiv Rau Cov Hlau, Cov Nitrogen Content Tsis Txwv. Cov Nitrogen Fixation Content Yuav Tsum Tau Qhia Hauv Daim Ntawv Pov Thawj Zoo. E. Thaum Siv Tag Nrho Aluminium, Tag Nrho Cov Aluminium Content Alt≥0020%.
