INCOLOY 825 (UNS N08825 / NS142)
Application
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.
Alloy 825 yakagadziridzwa 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 nickel yemukati inokwana kurwisa chloride-ion stress-corrosion cracking. Iyo nickel, yakabatana ne molybdenum nemhangura, inopawo kupikisa kwakanyanya mukudzikisa nharaunda senge dzine sulfuric uye phosphoric acid.
Iyo chromium uye molybdenum zvirimo zvakare inopa yakanaka pitting kuramba munzvimbo dzese kunze kwekunge yakasimba oxidizing chloride mhinduro. Inoshandiswa sechinhu chinoshanda munzvimbo dzakasiyana siyana dzemagadzirirwo, alloy 825 inochengetedza yakanaka mechanical zvivakwa kubva kune cryogenic tembiricha kusvika 1,000 ° F.
Kuwedzerwa kwetitanium kunodzikamisa Alloy 825 kupesana nekukurudzira mune yakashongedzwa mamiriro inoita kuti alloy irambe ichirwisa intergranular kurwiswa mushure mekuratidzwa kune tembiricha mumutsara unogonesa simbi isina kugadzikana isina kusimba. Kugadzirwa kweAlloy 825 kwakajairwa nickel-base alloys, ine zvinhu zviri nyore kuumbwa uye zvinogoneka neakasiyana maitiro.
Ichi chinyorwa chine yakanakisa kuumbwa, yakajairwa nickel-base alloys, ichibvumira kuti zvinhu zvigonyererwe kune diki radii. Kuvhara mushure mekukotama hakuwanzo kudikanwa.
Iyo yakafanana neiyo alloy 800 asi yakavandudza kuramba kune aqueous corrosion. Iyo ine yakanakisa kurwisa kune ese ekudzikisa uye oxidizing asidhi, kune kushushikana-kupwanya kwekuputika, uye kurwiswa kwenzvimbo sekunge gomba uye crevice corrosion. Alloy 825 inonyanya kupikisa sulfuric uye phosphoric acids. Iyi nickel simbi alloy inoshandiswa kugadzira makemikari, kusvibisa-kudzora midziyo, mafuta uye gasi pombi pombi, kugadzira mafuta enyukireya, kugadzira asidhi, uye midziyo yekunhonga.
