    A. Pamusoro pemagiredhi eQ345A neQ345B, simbi yacho inofanira kunge iine chimwe chezviyo zvakanatswa Al, Nb, V, uye Ti. Maererano nezvinodiwa, mutengesi anogona kuwedzera imwe kana zvimwe zvakanatswa zviyo zvezviyo. Iko kukosha kwepamusoro kuchave sekutsanangurwa mutafura. Kana yabatanidzwa, Nb + V + Ti haisi kupfuura 0.22% b. Kumagiredhi eQ345, Q390, Q420 neQ46O, Mo + Cr haina kudarika 0.30% c. Kana Cr naNi yegiredhi yega yega inoshandiswa sezvinhu zvakasara, zvirimo zveCr neNi hazvifanirwe kunge zvakakura kupfuura 0.30%; pazvinenge zvichidikanwa kuwedzera, zvirimo zvinofanirwa kusangana nezvinodiwa mutafura kana kutemerwa nemutengesi uye mutengi kuburikidza nekubvunzana.d. Kana mutengesi achigona kuve nechokwadi chekuti nitrogen yemukati inosangana nezvinodiwa mutafura, iyo nitrogen yemukati yekuongorora inogona kusaitwa. Kana Al, Nb, V, Ti uye mamwe alloy elements ane nitrogen fixation akawedzerwa kune simbi, iyo nitrogen content haina kukwana. Iyo nitrogen inogadzirisa zvemukati inofanirwa kutsanangurwa mune yemhando chitupa.
    E. Paunenge uchishandisa aruminiyamu yakazara, iyo yakazara aruminiyamu yemukati Alt ≥ 0020%.
