1.4021 stainless hlau khoom
1.4021 yog cov khoom siv stainless hlau, uas yog martensitic stainless hlau. 1.4021 muaj 13% chromium thiab me me ntawm carbon, manganese, silicon thiab lwm yam. Nov yog cov yam ntxwv tseem ceeb ntawm 1.4021:
High hardness: 1.4021 muaj hardness siab thiab tuaj yeem siv dav hauv kev tsim cov riam thiab txiav cov cuab yeej, cov cuab yeej phais, cov khoom siv, thiab lwm yam.
Zoo corrosion kuj: Vim nws cov ntsiab lus chromium siab, 1.4021 muaj corrosion kuj zoo thiab tuaj yeem siv rau hauv ib puag ncig uas muaj qee yam tshuaj lossis hauv qhov chaw ntub dej.
Nruab nrab weldability: 1.4021 tuaj yeem ua tiav thiab txuas nrog cov txheej txheem vuam zoo li TIG thiab MIG, tab sis qhov tsim nyog ua ntej ua kom sov thiab txias ntsuas yuav tsum tau ua thaum lub vuam txheej txheem.
Kev tuav tau zoo: 1.4021 yog ib qho yooj yim los tswj nws cov hardness thiab mechanical zog thaum kho cua sov.
Pheej yig: Piv nrog rau lwm cov ntaub ntawv stainless hlau, 1.4021 muaj tus nqi qis dua.
Nws yuav tsum tau muab sau tseg tias 1.4021 yog nquag hydrogen embrittlement rupture nyob rau hauv tej yam corrosive ib puag ncig, yog li ceev faj xaiv thiab tuav yuav tsum tau nyob rau hauv tej yam kev mob ntawm kev siv. Tsis tas li ntawd, 1.4021 kuj tseem ua rau pitting corrosion thiab nto puas, yog li yuav tsum tau saib xyuas thiab tu.
1.4021 yog martensitic stainless hlau, tseem hu ua 420 stainless hlau. Vim nws zoo heev corrosion kuj, hardness, txiav kev ua tau zoo thiab hnav tsis kam, nws yog dav siv nyob rau hauv manufacturing riam, hniav, khoom kho mob, mechanical qhov chaw, thiab lwm yam. Cov hauv qab no yog qhov zoo ntawm kev txhim kho thiab kev ceev faj ntawm 1.4021:
Qhov zoo:
1.4021 txoj kev loj hlob zoo nyob rau hauv kev ua lag luam yog feem ntau cuam tshuam nyob rau hauv cov nram qab no yam:
Cov khoom siv zoo: 1.4021 muaj qhov tawv tawv, siab hnav tsis kam thiab kev ua haujlwm zoo, thiab tsim nyog rau kev tsim cov cuab yeej txiav txiav, cov hniav, thiab lwm yam.
Zoo corrosion kuj: 1.4021 muaj corrosion kuj zoo heev thiab tuaj yeem tiv taus qhov yaig ntawm cov xov xwm corrosive. Nws yog tsim rau kev tsim khoom siv kho mob, khoom siv tshuaj, thiab lwm yam.
Tus nqi qis: Piv nrog rau lwm cov khoom siv hlau tsis muaj steel, tus nqi ntawm 1.4021 yog tus nqi qis, uas tuaj yeem txo cov nqi tsim khoom thiab txhim kho kev lag luam kev sib tw.
Kev ceev faj rau kev siv:
1.4021 yog nquag hnav, yog li cov txheej txheem tsim nyog thiab cov cuab yeej yuav tsum tau siv thaum ua haujlwm los tiv thaiv kev hnav ntau dhau.
Thaum vuam, 1.4021 yuav tsum siv cov txheej txheem vuam tsim nyog thiab cov khoom siv vuam, txwv tsis pub tawg thiab deformation yuav yooj yim tshwm sim.
Qhov saum npoo ntawm 1.4021 yog qhov yooj yim rau oxidation thiab corrosion, yog li yuav tsum tau saib xyuas thiab tu thaum siv kom tsis txhob muaj kab mob thiab corrosion.
Thaum siv 1.4021 los tsim cov khoom siv kho mob, lawv yuav tsum tau tsim, tsim thiab sim ua raws li cov qauv thiab cov lus qhia tshwj xeeb kom ntseeg tau cov khoom zoo thiab kev nyab xeeb.
Feem ntau hais lus, 1.4021, raws li cov khoom siv hlau tsis zoo, muaj kev cia siab zoo hauv kev txhim kho yav tom ntej. Raws li tib neeg qhov kev thov rau cov khoom siv zoo, cov ntaub ntawv ua tau zoo nce, 1.4021 yuav muaj ntau qhov kev thov ntau dua.
