Ngokwezidingo, umphakeli angakwazi ukwengeza izakhi zokusanhlamvu ezicwengisisiwe eyodwa noma ngaphezulu. Inani eliphakeme lizoba njengoba lishiwo kuthebula. Uma ihlanganiswa, i-Nb + V + Ti ayikho ngaphezu kuka-0.22%b. Kumabanga e-Q345, Q390, Q420 ne-Q46O, i-Mo + Cr ayikho ngaphezu kuka-0.30%c. Uma i-Cr ne-Ni yebanga ngalinye kusetshenziswa njengezakhi ezisele, okuqukethwe kwe-Cr ne-Ni akufanele kube kukhulu kuno-0.30%; lapho kudingekile ukwengeza, okuqukethwe kufanele kuhlangabezane nezidingo etafuleni noma kunqunywe umphakeli nomthengi ngokubonisana.d. Uma umphakeli engaqinisekisa ukuthi okuqukethwe yi-nitrogen kuyahlangabezana nezimfuneko ezisethebula, ukuhlaziywa kokuqukethwe kwe-nitrogen kungase kungenziwa. Uma i-Al, Nb, V, Ti nezinye izakhi ze-alloy ezine-nitrogen fixation zengezwa ensimbi, okuqukethwe kwe-nitrogen akunqunyelwe. Okuqukethwe kokulungisa i-nitrogen kufanele kucaciswe kusitifiketi sekhwalithi. E. Uma usebenzisa i-aluminium egcwele, ingqikithi yokuqukethwe kwe-aluminium Alt ≥ 0020%. |

A. Ukwengeza KumaBanga E-Q345A Nawe-Q345B, Insimbi Kufanele Iqukathe Okungenani Okukodwa Kwezinto Ezisanhlamvu Ezicwengisisiwe i-Al, Nb, V, kanye ne-Ti. Ngokuya Ngezidingo, Umphakeli Angengeza Okukodwa Noma Okuningi Okusanhlamvu Okucolisisiwe. Inani Eliphezulu Lizokuba Njengoba Lishiwo Kuthebula. Uma Ihlanganisiwe, i-Nb + V + Ti Ayingaphezu kuka-0.22%B. KumaBanga e-Q345, Q390, Q420 kanye ne-Q46O, i-Mo + Cr Ayinkulu Kuno-0.30%C.
