    A. Ngaphezu kwamazinga e-Q345A kanye ne-Q345B, insimbi kufanele ibe okungenani nenye yezinto zokusanhlamvu ezicwengisisiwe i-Al, Nb, V, kanye ne-Ti. Ngokwezidingo, umhlinzeki angangeza into eyodwa noma ngaphezulu yokusanhlamvu ecwengisisiwe. Inani eliphezulu kufanele libe njengoba kuchaziwe etafuleni. Uma kuhlanganiswe, i-Nb + V + Ti ayidluli ku-0.22%b. Kwamazinga e-Q345, Q390, Q420 kanye ne-Q46O, i-Mo + Cr ayidluli ku-0.30%c. Uma i-Cr ne-Ni zebanga ngalinye zisetshenziswa njengezinto ezisele, okuqukethwe kwe-Cr ne-Ni akufanele kube ngaphezu kuka-0.30%; uma kudingeka ukwengeza, okuqukethwe kufanele kuhlangabezane nezidingo ezisetafuleni noma kunqunywe umhlinzeki kanye nomthengi ngokubonisana.d. Uma umhlinzeki engaqinisekisa ukuthi okuqukethwe kwe-nitrogen kuhlangabezana nezidingo ezisetafuleni, ukuhlaziywa kokuqukethwe kwe-nitrogen kungenzeka kungenziwa. Uma i-Al, Nb, V, Ti kanye nezinye izinto ze-alloy ezine-nitrogen fixation zengezwa ensimbini, okuqukethwe kwe-nitrogen akukhawulelwe. Okuqukethwe kokulungiswa kwe-nitrogen kufanele kuchazwe esitifiketini sekhwalithi.

    • Amapayipi Ensimbi Angenamthungo Ngezinhloso Zesakhiwo, Amapayipi Ensimbi Angenamthungo Ezakhiwo Zemishini Ku-GB/8162-2008 Standard. Ochungechungeni lwe-seamless steel tube, kukhona uhlobo lwezinto ezibizwa ngokuthi i-Q345B seamless steel tube uchungechunge lwe-alloy ephansi. Ezintweni ze-alloy ephansi, le nto ivame kakhulu. Ishubhu lensimbi elingenamthungo le-Q345 uhlobo lwezinto zeshubhu lensimbi. I-Q iyinzuzo yale nto, kanti i-345 iyinzuzo yale nto, ecishe ibe yi-345. Futhi inani lenzuzo lizoncipha ngokwanda kobukhulu bento. Izinga le-Q345A, alilona ithonya; i-Q345B, ingumthelela wokushisa ojwayelekile wama-degree angu-20; ikilasi le-Q345C, ingumthelela wama-degree angu-0; i-Q345D, ingumthelela wama-degree angu-20; ikilasi le-Q345E, lisuse ama-degree angu-40.

    A. Ngaphezu kwamaBanga e-Q345A kanye ne-Q345B, iNsimbi Kufanele Iqukathe Okungenani eyodwa yama-Elements Okusanhlamvu Okucwengisisiwe i-Al, Nb, V, kanye ne-Ti. Ngokwezidingo, Umhlinzeki Angangeza i-Elements eyodwa noma ngaphezulu Okusanhlamvu Okucwengisisiwe. Inani Eliphezulu Kufanele Libe Njengoba Lichazwe KuThebula. Uma Kuhlanganisiwe, i-Nb + V + Ti Ayingaphezu kuka-0.22%B. KumaBanga e-Q345, Q390, Q420 kanye ne-Q46O, i-Mo + Cr Ayingaphezu kuka-0.30%C. Uma i-Cr kanye ne-Ni yeBanga ngalinye kusetshenziswa njengezinto ezisele, okuqukethwe kwe-Cr kanye ne-Ni akufanele kube ngaphezu kuka-0.30%; Uma kudingeka ukungezwa, okuqukethwe kufanele kuhlangabezane nezidingo kuThebula noma kunqunywe ngumhlinzeki kanye nomthengi ngokubonisana.D. Uma Umhlinzeki Engaqinisekisa Ukuthi Okuqukethwe kwe-Nitrogen Kuhlangabezana Nezidingo KuThebula, Ukuhlaziywa Kokuqukethwe kwe-Nitrogen Kungase Kungenziwa. Uma i-Al, i-Nb, i-V, i-Ti kanye nezinye izakhi ze-alloy ezine-nitrogen fixation zengezwe ensimbini, okuqukethwe yi-nitrogen akukhawulelwe.
