Dab tsi yog qhov tsis zoo ntawm UNS N08020?
UNS N08020 Taw qhia
Alloy 20, tseem hu ua Carpenter 20, yog nickel-hlau-chromium austenitic alloy tsim los muab siab tshaj plaws tiv thaiv corrosion los ntawm acids, tshwj xeeb tshaj yog sulfuric acid. Cov hlau muaj kev tiv thaiv zoo heev rau kev xeb, pitting corrosion thiab crevice corrosion tiv thaiv cov tshuaj uas muaj chloride thiab sulfuric acid, phosphoric acid, nitric acid thiab lwm yam tshuaj. Nws kuj muaj niobium, uas yog zoo tiv thaiv kab mob parasensitization thiab hluavtaws intergranular corrosion. Carpenter20 ua ke zoo corrosion kuj nrog txhua yam khoom thiab yog ib qho yooj yim los tsim. Txawm hais tias Ameslikas tsim los siv rau hauv kev lag luam sulfuric acid, Alloy 20 yog tam sim no dav siv nyob rau hauv ntau yam lag luam, nrog rau cov tshuaj, khoom noj khoom haus, tshuaj thiab yas industries. Tsis tas li ntawd, cov alloy yog siv nyob rau hauv cov cua kub exchangers, sib tov tso tsheb hlau luam, hlau tu thiab pickling khoom thiab kav.
Dab tsi yog qhov tsis zoo ntawm UNS N08020?
Qhov tsis zoo ntawm UNS N08020 feem ntau suav nrog tus nqi siab, kev ua haujlwm nyuaj thiab qee qhov kev txwv kev ua haujlwm.
Ua ntej, nyob rau hauv cov nqe lus ntawm tus nqi, txij li thaum N08020 alloy muaj zoo corrosion kuj thiab txhua yam khoom, nws cov nqi kuj yog siab, uas yuav ua rau nws tsis haum rau tej daim ntawv thov nrog tsawg pob nyiaj siv.
Qhov thib ob, kev ua haujlwm nyuaj, N08020 yog qhov nyuaj dua rau kev ua haujlwm. Cov khoom siv no yuav tsum tau siv cov cuab yeej ua haujlwm tshwj xeeb thiab thev naus laus zis, uas tsis yog tsuas yog ua rau cov txheej txheem tsim khoom nyuaj, tab sis kuj nce tus nqi ua raws li.
Thaum kawg, kev txwv kev ua haujlwm, txawm hais tias N08020 muaj kev tiv thaiv zoo heev rau sulfuric acid corrosion thiab zoo tiv thaiv chloride kev nyuaj siab corrosion tawg, tseem yuav muaj kev txwv hauv qee qhov chaw huab cua. Piv txwv li, nyob rau hauv cov ntsiab lus tshwj xeeb ntawm sulfuric acid los yog lwm qhov chaw corrosive heev, tej zaum yuav xav tau cov ntaub ntawv tshwj xeeb ntxiv kom tau raws li kev xav tau ntawm kev lag luam.
Hauv cov ntsiab lus, txawm hais tias UNS N08020 muaj ntau yam kev siv hauv ntau qhov kev lag luam, nws cov nqi, kev ua haujlwm nyuaj thiab cov kev txwv tshwj xeeb yuav tsum tau ntsuas thaum txiav txim siab nws siv.
