    A. Ukongeza kwiiklasi ze-Q345A kunye ne-Q345B, intsimbi kufuneka ibe nesinye sezinto zengqolowa ezicociweyo i-Al, i-Nb, i-V, kunye ne-Ti. Ngokweemfuno, umthengisi unokongeza enye okanye ngaphezulu izinto zengqolowa ezicociweyo. Ixabiso eliphezulu kufuneka libe njengoko kuchaziwe kwitheyibhile. Xa zidityanisiwe, i-Nb + V + Ti ayidluli kwi-0.22%b. Kwiiklasi ze-Q345, i-Q390, i-Q420 kunye ne-Q46O, i-Mo + Cr ayidluli kwi-0.30%c. Xa i-Cr kunye ne-Ni zeklasi nganye zisetyenziswa njengezinto eziseleyo, umxholo we-Cr kunye ne-Ni akufuneki ube ngaphezulu kwe-0.30%; xa kuyimfuneko ukongeza, umxholo kufuneka uhlangabezane neemfuno ezikwitheyibhile okanye umiselwe ngumthengisi kunye nomthengi ngokubonisana.d. Ukuba umthengisi unokuqinisekisa ukuba umxholo we-nitrogen uhlangabezana neemfuno ezikwitheyibhile, uhlalutyo lomxholo we-nitrogen alunakwenziwa. Ukuba i-Al, i-Nb, i-V, i-Ti kunye nezinye izinto ze-alloy ezine-nitrogen fixation zongezwa kwintsimbi, umxholo we-nitrogen awunqunyelwe. Umxholo wokulungiswa kwe-nitrogen kufuneka uchazwe kwisatifikethi somgangatho.
    E. Xa usebenzisa i-aluminium epheleleyo, umxholo we-aluminium iyonke yi-Alt ≥ 0020%.

Ityhubhu yentsimbi engenamthungo yebhoyila enoxinzelelo oluphezulu (GB5310-2018) isetyenziselwa ukuvelisa umphezulu webhoyila yoxinzelelo oluphezulu kunye noxinzelelo olungaphezulu koxinzelelo ngentsimbi yekhabhoni esemgangathweni ophezulu, intsimbi ye-alloy kunye netyhubhu yentsimbi engenamthungo engenamthungo engenamthungo.

    A. Ukongeza kwi-Q345A kunye ne-Q345B Grades, intsimbi kufuneka ibe ne-Finely One of the Refined Grades Al, Nb, V, kunye ne-Ti. Ngokweemfuno, umthengisi unokongeza i-Fined Grains Elements enye okanye ezingaphezulu. Ixabiso eliphezulu malibe njengoko kuchaziwe kwiTheyibhile. Xa zidityanisiwe, i-Nb + V + Ti ayidluli kwi-0.22%B. Kwi-Q345, Q390, Q420 kunye ne-Q46O Grades, i-Mo + Cr ayidluli kwi-0.30%C. Xa i-Cr kunye ne-Ni zeBanga ngalinye zisetyenziswa njengezinto eziseleyo, umxholo we-Cr kunye ne-Ni akufuneki ube ngaphezu kwe-0.30%; xa kuyimfuneko ukongeza, umxholo kufuneka uhlangabezane neemfuno kwiTheyibhile okanye umiselwe ngumthengisi kunye nomthengi ngokubonisana.D. Ukuba umthengisi unokuqinisekisa ukuba umxholo we-nitrogen uyahlangabezana neemfuno kwiTheyibhile, uhlalutyo lomxholo we-nitrogen alunakuqhutywa. Ukuba i-Al, i-Nb, i-V, i-Ti kunye nezinye izinto ze-alloy ezine-nitrogen fixation zongezwa kwintsimbi, umxholo we-nitrogen awukhawulelwanga. umxholo we-nitrogen fixation kufuneka uchazwe kwisatifikethi somgangatho. E. Xa usebenzisa i-Aluminium epheleleyo, i-Alt yoMxholo we-Aluminium iyonke≥0020%.
