    A. Ngaphezu kwe-Q345A nama-Q345B amamaki, insimbi kufanele iqukathe okungenani enye yezinto zokusanhlamvu ezicwengekile i-Al, Nb, v, neTi. Ngokwezidingo, umphakeli angangeza izinto eyodwa noma eziningi ezicwengekile zokusanhlamvu. Inani eliphakeme lizobe licacisiwe etafuleni. Lapho kuhlanganiswe, i-NB + V + TI ayikho ngaphezu kwe-0.22% B. Ku-Q345, Q390, Q420 nama-Q46o amamaki, uMo + Cr akakhulu ka-0.30% c. Lapho u-Cr ne-night ngayinye esetshenziswa njengezinto ezisele, okuqukethwe kwe-CR ne-NI akufanele kube kukhulu kune-0.30%; Lapho kunesidingo sokungeza, okuqukethwe kufanele kuhlangabezane nezidingo etafuleni noma kunqunywe ngumhlinzeki kanye nomthengi ngokubonisana.D. Uma umphakeli eqinisekisa ukuthi okuqukethwe kwe-nitrogen kuhlangabezana nezidingo etafuleni, ukuhlaziywa kokuqukethwe kwe-nitrogen kungenzeka kungenziwa. Uma u-Al, NB, v, TI nezinye izinto ze-alloy ezinokulungiswa kwe-nitrogen zingezwa ensimbi, okuqukethwe kwe-nitrogen akunqunyelwe. Okuqukethwe kwe-nitrogen fixeration kufanele kuchazwe isitifiketi sekhwalithi.

    A. Ngaphezu kwe-Q345A nama-Q345B amamaki, insimbi kufanele iqukathe okungenani enye yezinto zokusanhlamvu ezicwengekile i-Al, Nb, v, neTi. Ngokwezidingo, umphakeli angangeza izinto eyodwa noma eziningi ezicwengekile zokusanhlamvu. Inani eliphakeme lizobe licacisiwe etafuleni. Lapho kuhlanganiswe, i-NB + V + TI ayikho ngaphezu kwe-0.22% B. Ku-Q345, Q390, Q420 nama-Q46o amamaki, uMo + Cr akakhulu ka-0.30% C. Lapho u-Cr ne-night ngayinye esetshenziswa njengezinto ezisele, okuqukethwe kwe-CR ne-NI akufanele kube kukhulu kune-0.30%; Lapho kunesidingo sokungeza, okuqukethwe kufanele kuhlangabezane nezidingo etafuleni noma kunqunywe ngumhlinzeki kanye nomthengi ngokubonisana.D. Uma umphakeli eqinisekisa ukuthi okuqukethwe kwe-nitrogen kuhlangabezana nezidingo etafuleni, ukuhlaziywa kokuqukethwe kwe-nitrogen kungenzeka kungenziwa. Uma u-Al, NB, v, TI nezinye izinto ze-alloy ezinokulungiswa kwe-nitrogen zingezwa ensimbi, okuqukethwe kwe-nitrogen akunqunyelwe. Okuqukethwe kwe-nitrogen fixeration kufanele kuchazwe isitifiketi sekhwalithi. E. Lapho usebenzisa i-aluminium ephelele, okuqukethwe okuphelele kwe-aluminium alt≥0020%.
