321 stainless hlau tube corrosion resistant
321 stainless hlau kav muaj zoo heev tiv thaiv corrosion. Lub xub ntiag ntawm chromium (17 feem pua rau 19 feem pua ) tsim cov txheej txheem oxide passive ntawm cov yeeb nkab, tiv thaiv nws los ntawm oxidation thiab corrosion nyob rau hauv ntau qhov chaw. Qhov sib ntxiv ntawm titanium (txog 0.70 feem pua) ) ntxiv txhim kho nws cov kev tiv thaiv rau intergranular corrosion, ua rau nws tsim nyog rau cov ntawv thov cuam tshuam rau qhov kub thiab txias.

Nov yog cov lus piav qhia ntxaws txog lawv cov kev tiv thaiv corrosion:
1, Chromium Cov ntsiab lus: 321 stainless hlau muaj qhov tseem ceeb ntawm chromium (17 feem pua rau 19 feem pua). Chromium yog lub ntsiab alloying nyob rau hauv stainless hlau uas muab nws corrosion kuj. Nws tsim ib txheej nyias, passive oxide nyob rau saum npoo ntawm cov yeeb nkab thaum raug cov pa oxygen hauv qhov chaw. Cov oxide txheej no ua raws li kev tiv thaiv kev tiv thaiv, tiv thaiv ntxiv oxidation thiab corrosion ntawm cov hlau hauv qab.
2, Passivation: Lub passive oxide txheej tsim nyob rau saum npoo ntawm 321 stainless hlau yog nws tus kheej-repairing thiab nws tus kheej-renewing. Yog hais tias qhov chaw yog khawb los yog puas, cov chromium nyob rau hauv cov hlau reacts nrog oxygen los tsim cov txheej txheem oxide tiv thaiv. Cov txheej txheem no yog hu ua passivation, thiab nws pab tswj kev tiv thaiv corrosion ntawm cov yeeb nkab thaum lub sijhawm.
3, Resistance rau General Corrosion: 321 stainless hlau kav muaj zoo heev tiv thaiv corrosion nyob rau hauv ntau qhov chaw. Lawv tuaj yeem tiv taus cov dej noo, huab cua puag ncig, thiab ntau yam corrosive media, nrog rau cov organic acids, alkaline daws, thiab oxidizing agents. Qhov no ua rau lawv tsim nyog rau cov ntawv thov hauv cov chaw ua tshuaj, qhov twg cov kav dej yuav tuaj yeem sib cuag nrog ntau yam tshuaj.
4, Intergranular Corrosion Resistance: Qhov sib ntxiv ntawm titanium (txog 0.70 feem pua) ) nyob rau hauv 321 stainless hlau ho txhim kho nws tsis kam mus rau intergranular corrosion. Intergranular corrosion yog ib hom kev xeb uas tshwm sim raws li cov ciaj ciam ntawm cov hlau tsis muaj steel, ua rau cov qauv tsis muaj zog thiab tsis ua haujlwm. Titanium reacts nrog carbon nyob rau hauv cov hlau los tsim ruaj khov titanium carbides, tiv thaiv cov chromium los ntawm depleting ntawm grain.
ciam teb thiab yog li khaws cov corrosion kuj ntawm cov yeeb nkab.
5, High-Temperature Corrosion Resistance: 321 stainless hlau kav zoo heev hauv kev tiv thaiv corrosion ntawm qhov kub siab. Lawv tuaj yeem tiv taus qhov kub txog li 900 degree (1652 degree F) yam tsis muaj kev puas tsuaj loj ntawm lawv cov corrosion kuj. Qhov no ua rau lawv tsim nyog rau cov ntawv thov hauv cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov pa hluav taws xob uas muaj qhov kub thiab txias.
