    a.Ukongeza kwi-Q345A kunye ne-Q345B amabakala, intsimbi kufuneka iqulethe ubuncinane enye yezinto eziziinkozo ezicocekileyo i-Al, Nb, V, kunye ne-Ti. Ngokweemfuno, umthengisi unokongeza enye okanye ngaphezulu kwezinto eziziinkozo ezicocekileyo. Elona xabiso liphezulu liyakuba njengoko lichaziwe kwitheyibhile. Xa idibene, i-Nb + V + Ti ayikho ngaphezu kwe-0.22%b. Kwi-Q345, Q390, Q420 kunye ne-Q46O amabakala, i-Mo + Cr ayikho ngaphezu kwe-0.30%c. Xa i-Cr kunye ne-Ni yebakala ngalinye zisetyenziswa njengezinto ezishiyekileyo, umxholo we-Cr no-Ni akufanele ube mkhulu kune-0.30%; xa kuyimfuneko ukongeza, umxholo kufuneka uhlangabezane neemfuno kwitheyibhile okanye unqunywe ngumthengisi kunye nomthengi ngokubonisana.d. Ukuba umthengisi unokuqinisekisa ukuba umxholo we-nitrogen uhlangabezana neemfuno kwitheyibhile, uhlalutyo lomxholo we-nitrogen alunakwenziwa. Ukuba i-Al, i-Nb, i-V, i-Ti kunye nezinye izinto ze-alloy kunye nokulungiswa kwe-nitrogen zongezwa kwintsimbi, umxholo we-nitrogen awukhawulelwanga. Umxholo wokulungiswa kwenitrogen kufuneka ucaciswe kwisiqinisekiso somgangatho.e. Xa usebenzisa i-aluminium epheleleyo, umxholo we-aluminium opheleleyo Alt ≥ 0020%.
