1.4501 yog stainless hlau uas muaj 20.5 feem pua chromium, 24 feem pua nickel, 6.5 feem pua molybdenum, thiab 0.22 feem pua nitrogen. Nws muaj corrosion kuj zoo heev thiab siab corrosion kuj nyob rau hauv corrosive media xws li muaj zog acids, alkalis, thiab chlorides. Feem ntau siv rau hauv kev tsim cov khoom siv tshuaj, cov khoom siv marine, cov khoom siv ua zaub mov, thiab lwm yam.
Yog vim li cas rau intergranular corrosion yog hais tias thaum lub sij hawm vuam txheej txheem, weld cheeb tsam tau raug rau high-temperature tshav kub kev kho mob, uas ua rau depletion ntawm chromium ntsiab nyob rau hauv lub 1.4501 grain ciam teb, tsim ib tug tsawg chromium cheeb tsam, ua rau lub grain ciam teb ntau dua. corrosion. 1.4501 yog ib qho corrosion-resistant thiab aesthetically pleasing alloy khoom muaj xws li hlau, chromium, thiab npib tsib xee.
Cov tshuaj muaj pes tsawg leeg ntawm 1.4501 yog:
chromium (Cr): 16. .95 feem pua -1.20 feem pua , Silicon (Si): Tsawg dua lossis sib npaug rau 1.0 feem pua , Manganese (Mn): Tsawg dua lossis sib npaug li 1.0 feem pua ,
Phosphorus (P): Tsawg dua lossis sib npaug rau {{0}}}.04 feem pua , Sulfur (S): Tsawg dua lossis sib npaug li 0.03 feem pua .
Los ntawm kev suav cov khoom siv thiab simulation thev naus laus zis, qhov cuam tshuam ntawm cov ntsiab lus sib txawv ntawm cov qauv thiab kev ua tau zoo ntawm 1.4501 tuaj yeem kwv yees ntau dua, muab kev taw qhia kom raug rau cov khoom tsim;
Tshuaj corrosion yog hais txog kev puas tsuaj ncaj qha los ntawm qhov nruab nrab corrosive mus rau 1.4501, thaum electrochemical corrosion hais txog kev tsim lub roj teeb ntawm 1.4501 thiab cov electrolyte hauv nruab nrab corrosive, qhov twg tam sim no dhau los ntawm cov ions hauv nruab nrab thiab hlau atoms raug xa mus. , thaum kawg ua rau hlau corrosion. 1.4501, raws li cov khoom siv dav siv hauv kev lag luam thiab pej xeem, nws qhov kev ua tau zoo corrosion yog qhov tseem ceeb rau nws txoj kev pab cuam lub neej thiab kev nyab xeeb.
Hauv cov ntsiab lus, cov ntsiab lus saum npoo av xa mus rau qee cov ntsiab lus ntxiv hauv 1.4501, xws li sulfur, potassium, sodium, thiab carbon. Lawv tuaj yeem txhawb kev tsim cov oxide zaj duab xis, yog li txhim kho corrosion kuj ntawm 1.4501.
