    A. Ukongeza kumabakala e-Q345A kunye ne-Q345B, 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. Kwinqanaba le-Q345, Q390, Q420 kunye ne-Q46O, 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 ugqitywe 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%.

    A. Ukongeza kwi-Q345A kunye ne-Q345B amaBanga, iNsimbi kufuneka iqulathe ubuncinci iNqanaba yeeNkozo eziCokisiweyo i-Al, i-Nb, i-V, kunye ne-Ti. NgokweeMfuno, uMboneleli unokongeza enye okanye ngaphezulu kwezinto eziziinkozo ezisulungekisiweyo. Elona xabiso liPhezulu liya kuba njengoko lichaziwe kwiThebhile. Xa Idityanisiwe, i-Nb + V + Ti Ayikho Ngaphezulu kwe-0.22%B. Kwi-Q345, i-Q390, i-Q420 kunye ne-Q46O amaBanga, i-Mo + Cr ayikho ngaphezu kwe-0.30% C. Xa i-Cr kunye ne-Ni yeBanga ngalinye zisetyenziswa njengezinto ezishiyekileyo, umxholo we-Cr kunye no-Ni akufanele ube mkhulu kune-0.30%; Xa Kuyimfuneko Ukongezwa, Umxholo kufuneka uhlangabezane neemfuno kwiThebhile okanye ugqitywe nguMboneleli kunye nomthengi ngokubonisana.D. Ukuba uMboneleli unokuqinisekisa ukuba uMxholo weNitrojeni udibana neeMfuno eziPhakathi kweThebhile, uHlalutyilo loMxholo weNitrojeni alunakwenziwa. Ukuba i-Al, i-Nb, i-V, i-Ti kunye nezinye izinto ze-alloy kunye ne-Nitrogen Fixation zongezwa kwiNsimbi, i-Nitrogen Content ayikhawulelwanga. I-Nitrogen Fixation Content kufuneka icaciswe kwiSatifikethi soMgangatho. E. Xa usebenzisa i-Aluminiyam epheleleyo, i-Aluminiyam iyonke Umxholo we-Alt≥0020%.
