    A. Marka lagu daro darajooyinka Q345A iyo Q345B, birta waa in ay ka kooban tahay ugu yaraan mid ka mid ah walxaha badarka la safeeyey ee Al, Nb, V, iyo Ti. Marka loo eego baahiyaha, alaab-qeybiyuhu wuxuu ku dari karaa hal ama in ka badan oo walxood oo la safeeyey. Qiimaha ugu badan waa inuu ahaadaa sida lagu qeexay shaxda. Marka la isku daro, Nb + V + Ti kama badna 0.22%b. Q345, Q390, Q420 iyo Q46O, Mo + Cr kama badna 0.30%c. Marka Cr iyo Ni ee fasal kasta loo isticmaalo hadhaaga, waxa ku jira Cr iyo Ni waa in aanay ka badnaan 0.30%; marka ay lagama maarmaan noqoto in wax lagu daro, waxa ku jira waa in ay buuxiyaan shuruudaha shaxda ama ay go'aamiyaan alaab-qeybiyaha iyo iibsadaha iyada oo la tashanayo.d. Haddii alaab-qeybiyuhu uu hubin karo in waxa ku jira nitrogen uu buuxiyo shuruudaha shaxda, falanqaynta ka kooban nitrogenga waxa laga yaabaa in aan la samayn. Haddii Al, Nb, V, Ti iyo walxo kale oo alloy ah oo leh hagaajinta nitrogen lagu daro birta, nuxurka nitrogen ma xaddidna. Nuxurka hagaajinta nitrogen waa in lagu qeexaa shahaadada tayada.
    E. Marka la isticmaalayo aluminium buuxa, wadarta aluminium ka kooban Alt ≥ 0020%.

    A. Marka lagu daro darajooyinka Q345A iyo Q345B, birtu waa inay ka kooban tahay ugu yaraan mid ka mid ah Walxaha hadhuudhka ee la safeeyey Al, Nb, V, iyo Ti. Marka loo eego baahiyaha, alaab-qeybiyuhu wuxuu ku dari karaa hal ama in ka badan oo walxood oo la safeeyey. Qiimaha ugu badan waa inuu noqdaa sida ku cad shaxda. Marka la isku daro, Nb + V + Ti kama badna 0.22% B. Heerarka Q345, Q390, Q420 iyo Q46O, Mo + Cr kama badna 0.30% C. Marka Cr iyo Ni ee Fasalka kasta loo isticmaalo sidii Walxaha hadhay, waxa ku jira Cr iyo Ni waa in aanay ka badnaan 0.30%; Marka ay lama huraan tahay in wax lagu daro, waxa ku jira waa in ay buuxiyaan shuruudaha shaxda ama ay go'aamiyaan alaab-qeybiyaha iyo iibsadaha iyada oo la tashanayo.D. Haddii alaab-qeybiyuhu uu hubin karo in waxa Nitrojiinku ka kooban yahay uu buuxiyo shuruudaha shaxda, Falanqaynta waxa ku jira Nitrogen lagama yaabo in la sameeyo. Haddii Al, Nb, V, Ti iyo Walxaha kale ee Alloy ee leh Fixinta Nitrojiin lagu daro Birta, Nuxurka Nitrogen-ku ma xaddidna. Nuxurka Hagaajinta Nitrogen waa in lagu qeexaa Shahaadada Tayada. E. Marka la isticmaalayo aluminium buuxa, wadarta guud ee aluminium ka kooban Alt≥0020%.
