    A. Marka laga soo tago 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. Sida waafaqsan baahiyaha, alaab-qeybiyuhu wuxuu ku dari karaa hal ama in ka badan walxaha hadhuudhka ee la safeeyey. Qiimaha ugu badan waa inuu ahaadaa sida ku cad jadwalka. Marka la isku daro, Nb + V + Ti kama badna 0.22%b. Darajooyinka Q345, Q390, Q420 iyo Q46O, Mo + Cr kama badna 0.30%c. Marka Cr iyo Ni ee darajo kasta loo isticmaalo sidii walxaha haraaga ah, waxa ku jira Cr iyo Ni waa inaysan ka badnaan 0.30%; marka loo baahdo in lagu daro, waxa ku jira waa inuu buuxiyaa shuruudaha ku jira jadwalka ama waxaa go'aamiya alaab-qeybiyaha iyo iibsadaha iyada oo loo marayo la-tashi.d. Haddii alaab-qeybiyuhu uu hubin karo in waxa ku jira nitrogen uu buuxiyo shuruudaha ku jira jadwalka, falanqaynta waxa ku jira nitrogen lama sameyn karo. Haddii Al, Nb, V, Ti iyo walxaha kale ee birta ah ee leh hagaajinta nitrogen lagu daro birta, waxa ku jira nitrogen ma xaddidna. Waxyaabaha ku jira haynta nitrogen waa in lagu qeexaa shahaadada tayada.

    A. Marka laga soo tago Darajooyinka Q345A iyo Q345B, Birtu waa inay ka koobnaataa ugu yaraan mid ka mid ah Walxaha Badarka ee la safeeyey Al, Nb, V, iyo Ti. Sida ku xusan baahiyaha, Alaab-qeybiyuhu wuxuu ku dari karaa hal ama in ka badan Walxaha Badarka ee la safeeyey. Qiimaha ugu badan waa inuu ahaadaa sida ku cad Shaxda. Marka la isku daro, Nb + V + Ti Maaha wax ka badan 0.22%B. Darajooyinka Q345, Q390, Q420 iyo Q46O, Mo + Cr Maaha wax ka badan 0.30%C. Marka Cr iyo Ni ee Darajada kasta loo isticmaalo Walxaha Haray, Waxyaabaha ku jira Cr iyo Ni waa inaysan ka badnaan 0.30%; Marka loo baahdo in lagu daro, Waxyaabaha ku jira waa inay buuxiyaan Shuruudaha ku jira Shaxda ama ay go'aamiyaan Alaab-qeybiyaha iyo Iibsadaha iyada oo loo marayo La-tashi.D. Haddii Alaab-qeybiyuhu uu hubin karo in Waxyaabaha ku jira Naytarojiinku ay buuxiyaan Shuruudaha ku jira Shaxda, Falanqaynta Mawduuca Naytarojiinku Lama Sameyn Karo. Haddii Al, Nb, V, Ti iyo Walxaha kale ee Daawaha leh ee leh Naytarojiin lagu daro Birta, Waxyaabaha ku jira Naytarojiinku ma xaddidna. Waxyaabaha ku jira Naytarojiinku waa in lagu qeexaa Shahaadada Tayada. E. Marka la isticmaalayo Aluminium Buuxa, Wadarta Guud ee Aluminium-ka Alt≥0020%.
