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 lagu daro, waxa ku jira waa in ay buuxiyaan shuruudaha miiska 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 waxa ku jira nitrogen lama samayn karo. 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%. |
