Kowiri tira Hiko E347-16
Ka taea te wehewehe i te hiko hiko kowiri tira ki roto i te chromium kowiri tira hiko me te chromium nickel kowiri hiko hiko, enei momo e rua o nga hiko i runga i te paerewa o te motu, e rite ana ki te aromatawai GB / T983 -1995.Chromium kowiri tira he etahi parenga waikura (waikawa waikura, waikawa waro, cavitation) ātete wera me te waikura ātete.I te nuinga o te waa ka tohua hei taputapu taputapu mo te teihana hiko, te ahumahi matū, te hinu me etahi atu.Ko te chromium kowiri tira te tikanga rawakore weldability, kia whakarongo ki te tukanga fehokotaki'anga, tikanga maimoatanga wera me te kōwhiringa o te hiko tika.Chromium-nickel kowiri tira hiko he pai te parenga waikura me te aukati waikura, e whakamahia nuitia ana i roto i te umanga matū, tongi, hinu, miihini miihini rongoa.I roto i te tikanga ki te aukati i te waikura i waenganui i nga kanohi e tika ana ki te whakawera, te naianei fehokotaki'anga e kore e nui rawa, iti iho i te waro maitai hiko e pā ana ki 20% , kia kaua e roa rawa arc, mātao tere i waenganui i nga paparanga, ki te pirepire kuiti he tika.
