A. I tua atu i nga tohu Q345A me te Q345B, me uru ki roto i te maitai tetahi o nga huānga witi parakore Al, Nb, V, me Ti. E ai ki nga hiahia, ka taea e te kaiwhakarato te taapiri i tetahi, neke atu ranei nga huanga witi parakore. Ko te uara morahi kia rite ki te ripanga. Ina whakakotahi, ko Nb + V + Ti kaore e neke ake i te 0.22%b. Mo nga tohu Q345, Q390, Q420 me Q46O, Mo + Cr kaore e nui ake i te 0.30%c. Ina whakamahia te Cr me te Ni o ia karaehe hei huānga toenga, ko te ihirangi o Cr me Ni kia kaua e nui ake i te 0.30%; i te wa e tika ana ki te taapiri, me tutuki nga ihirangi ki nga whakaritenga o te teepu, me whakatau ranei e te kaiwhakarato me te kaihoko ma te korerorero.d. Mena ka taea e te kaiwhakarato te whakarite kia tutuki te ihirangi hauota ki nga whakaritenga o te ripanga, kaore pea e mahia te tātaritanga hauota. Mēnā ka tāpirihia te Al, Nb, V, Ti me ētahi atu huānga koranu me te whakatika hauota ki te maitai, karekau he iti te ihirangi hauota. Ko te ihirangi whakatika hauota me tohu ki te tiwhikete kounga. E. A, no te whakamahi i te konumohe katoa, te tapeke ihirangi konumohe Alt ≥ 0020%. |
