     a.  Ukongezelela Q345A kunye Q345B amabakala, ngentsimbi kufuneka iqulathe ubuncinane omnye izinto okuziinkozo evuthiswe Al, yesiqephu, V, kunye Ti. Ngokutsho iimfuno, umthengisi ongeze omnye okanye kwalungiswa ngaphezulu iziqalelo okuziinkozo. Elona xabiso liphezulu liya kuba njengoko kucacisiwe kule theyibhile. Xa zidibene, yesiqephu + V + Ti ayikho ngaphezu kwe 0.22% b. Kuba Q345, Q390, Q420 kunye Q46O amabakala, Mo + Cr umkhulu 0.30% c. Xa Cr no Ni ekufundwa phantsi kwazo kwibanga ngalinye zisetyenziswa njengezinto eyintsalela, kufuneka ungabi ngaphezu 0.30% umxholo Kr and Ni; xa kuyimfuneko ukongeza, isiqulatho kufuneka ihlangabezane neemfuno kwitheyibhile okanye kumiselwa kumthengisi size umthengi ngokubonisana. d. Ukuba nomthengisi uqinisekise ukuba okubhalwe nitrogen uyahlangabezana neemfuneko kwitheyibhile, uhlalutyo lomxholo nitrogen akufunekanga ukwenziwa. Ukuba Al, yesiqephu, V, Ti kunye nezinye izinto ingxubevange kunye nitrogen nitrogen ezidityaniswe ngentsimbi, isiqulatho nitrogen kuphela. Umxholo kuba ngundaba-nitrogen kufuneka zicaciswe kwisiqinisekiso esemgangathweni.

    e. Xa usebenzisa aluminium ngokupheleleyo, iyonke Alt isiqulatho aluminiyam ≥ 0020%.
