a.Pamusoro peQ345A uye Q345B mamakisi, simbi inofanirwa kunge iine imwe yezvakanatswa zviyo zvinhu Al, Nb, V, uye Ti. Maererano nezvinodiwa, mutengesi anogona kuwedzera imwe kana zvimwe zvakanatswa zviyo zvezviyo. Iko kukosha kwepamusoro kuchave sekutsanangurwa mutafura. Kana yasanganiswa, Nb + V + Ti haina kupfuura 0.22%b. Kune Q345, Q390, Q420 uye Q46O mamakisi, Mo + Cr haina kukura kupfuura 0.30%c. Kana Cr uye Ni yegiredhi yega yega inoshandiswa seyasara zvinhu, 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%. |
