    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%.

Inqanaba le-Q345A, alikho impembelelo; I-Q345B, yimpembelelo ye-20 yeqondo lokushisa eliqhelekileyo; Iklasi ye-Q345C, yimpembelelo ye-degree degree; I-Q345D, yi-20 degree impembelelo; Iklasi ye-Q345E, thabatha i-40 degrees. Ixabiso lempembelelo likwahlukile kumaqondo obushushu ahlukeneyo. Q345A, Q345B, Q345C, Q345D, Q345E. Eli libakala lokwahlula, elimele, ubukhulu becala ifuthe lobushushu lahlukile.

    Umgangatho wokwenziwa

    1. Umbhobho ongenamthungo wesakhiwo (GB / T8162-2018) ngumbhobho wensimbi ongenamthungo kwisakhiwo esiqhelekileyo kunye nesakhiwo somatshini. 2. Umbhobho wensimbi ongenamthungo wokuthuthwa kwamanzi (GB/T8163-2018) isetyenziselwa ukuhambisa amanzi, i-oyile, igesi kunye nolunye ulwelo kumbhobho wensimbi ongenamthungo jikelele. 3. Iityhubhu zentsimbi ezingenamthungo kwiibhoyila zoxinzelelo oluphantsi noluphakathi (GB3087-2018) zisemgangathweni ophezulu wekhabhoni yesakhiwo sentsimbi eshushu-eqengqelekayo kunye nebandayo (eqengqelekayo) iityhubhu zentsimbi ezingenamthungo, ezisetyenziselwa ukuvelisa imibhobho yomphunga eshushu kakhulu, imibhobho yamanzi abilayo eyahlukeneyo. izakhiwo zeebhoyila zoxinzelelo oluphantsi kunye oluphakathi kunye nemibhobho yomphunga eshushu kakhulu kunye nemibhobho yezitena ze-arch kwiibhoyila ze-locomotive. 4. Ityhubhu yentsimbi engenamthungo kwibhoyila yoxinzelelo oluphezulu (i-GB5310-2018) isetyenziselwa ukuvelisa uxinzelelo oluphezulu kunye noxinzelelo olungaphezulu koxinzelelo lwamanzi ityhubhu yebhoyila yokufudumeza indawo enomgangatho ophezulu wekhabhoni yentsimbi, intsimbi yealloy kunye nobushushu obungenasici.

    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%.
