    A. Ngokungeziwe kumabanga e-Q345A ne-Q345B, insimbi kufanele iqukathe okungenani ingxenye eyodwa yezinto ezisanhlamvu ezicwengisisiwe i-Al, Nb, V, ne-Ti. 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.

    • Amashubhu Ensimbi Angenamthungo Wezinjongo Zesakhiwo, Amashubhu Ensimbi Angenamthungo Wezakhiwo Zemishini Ku-GB/8162-2008 Standard. Ochungechungeni lweshubhu yensimbi engenamthungo, kukhona uhlobo lwempahla olubizwa nge-Q345B ishubhu lensimbi engenamthungo uchungechunge lwe-alloy ephansi. Ku-low alloy material, le nto ivame kakhulu. I-Q345 ithubhu yensimbi engenamthungo iwuhlobo lwensimbi yensimbi. I-Q iyisivuno salokhu kwaziswa, futhi i-345 iyisivuno salokhu kwaziswa, okungaba ngu-345. Futhi inani lokukhiqiza lizokwehla ngokunyuka kokuqina kwezinto ezibonakalayo.
