Alloy 825 Tubing
Alloy 825 is an austenitic nickel-iron-chromium alloy zvakare inotsanangurwa nekuwedzera kwe molybdenum, mhangura uye titanium.Yakagadzirwa kuti ipe kupikisa kwakasarudzika kune dzakawanda nharaunda dzinoparadza, zvese oxidizing uye kuderedza.Iine nickel yemukati inosiyana pakati pe38% -46%, giredhi iri rinoratidza kushorwa kupikisa kushushikana kwecorrosion cracking (SCC) inokonzerwa nemakloridi uye alkalis.Iyo chromium uye molybdenum zvemukati zvinopawo kunaka kwegomba kuramba munzvimbo dzese kunze kwekunge zvine oxidizing chloride mhinduro.Inoshandiswa sechinhu chinoshanda munzvimbo dzakasiyana siyana dzemagadzirirwo, alloy 825 inochengetedza yakanaka mechanical zvivakwa kubva kune cryogenic tembiricha kusvika 1,000 ° F.
