Stainless hlau daim hlau muaj peev xwm tiv taus atmospheric oxidation, uas yog, xeb kuj

Ntxiv nrog rau cov hlau, stainless hlau daim hlau kuj muaj chromium, npib tsib xee, txhuas, silicon, thiab lwm yam. Cov ntsiab lus chromium ntawm cov hlau tsis zoo li qub feem ntau tsis tsawg dua 12%, thiab txawm tias mus txog 18%. Tom qab ntxiv cov khoom xws li chromium rau hlau, cov khoom ntawm cov hlau tuaj yeem hloov tau. Piv txwv li, cov qauv molecular ntawm cov hlau yog zoo ib yam, thiab ib tug ntom oxide tiv thaiv zaj duab xis yog yooj yim tsim nyob rau saum npoo ntawm cov hlau, zoo heev txhim kho corrosion kuj ntawm stainless hlau daim hlau. Yog li stainless hlau daim hlau tuaj yeem tiv thaiv corrosion ntawm hluav taws, dej, kua qaub, alkali, thiab ntau yam kev daws teeb meem, thiab tsis xeb. Cov kws tshaj lij tau pom tias qhov sib txawv ntawm cov qauv hlau sab hauv, qhov ze rau ntau yam khoom sib txuas, ua rau nws nyuaj rau cov khoom corrosive los txeeb. Tsis tas li ntawd, ib txheej ntawm oxide tiv thaiv zaj duab xis yog txuas rau saum npoo, ib yam li muab armor rau ntawm hlau, uas ib txwm ua rau nws tsis tshua muaj xeb.

Vim li cas stainless hlau phaj kuj xeb? Thaum cov xim xim av xeb (spots) tshwm rau saum npoo ntawm stainless hlau daim hlau thiab cov kav dej, cov neeg xav tsis thoob: lawv ntseeg tias "stainless hlau daim hlau tsis xeb, thiab yog xeb, nws tsis yog stainless hlau daim hlau, tej zaum yuav muaj teeb meem. nrog cov hlau zoo. " Qhov tseeb, qhov no yog ib qho kev pom yuam kev uas tsis muaj kev nkag siab ntawm cov hlau tsis muaj hlau. Stainless hlau daim hlau kuj tuaj yeem xeb nyob rau hauv qee yam mob.

Stainless hlau daim hlau muaj peev xwm tiv taus atmospheric oxidation, uas yog xeb kuj, thiab kuj muaj peev xwm corrode nyob rau hauv xov xwm uas muaj kua qaub, alkali, thiab ntsev, uas yog corrosion kuj. Tab sis qhov loj ntawm nws cov corrosion kuj txawv nrog cov tshuaj muaj pes tsawg leeg, lub xeev additive, kev siv, thiab hom ntawm ib puag ncig nruab nrab ntawm cov hlau nws tus kheej. Piv txwv li, 304 cov kav hlau steel muaj qhov xeb zoo heev hauv qhov chaw qhuav thiab huv si, tab sis thaum tsiv mus rau thaj chaw ntug dej hiav txwv, lawv yuav xeb sai sai hauv hiav txwv huab cua uas muaj cov ntsev ntau; 304 # stainless hlau phaj txias cia phaj ua tau zoo. Yog li ntawd, tsis yog txhua hom stainless hlau phaj tuaj yeem tiv taus corrosion thiab xeb hauv ib puag ncig.

Stainless hlau daim hlau tso cia rau ntawm nyias, thiab ntom ntom nti cov kua txiv (Oxide zaj duab xis (li no tau txais lub peev xwm tiv thaiv corrosion. Ib zaug yog vim li cas, cov yeeb yaj kiab nyias no tau raug puas ntsoog tas li, thiab cov pa oxygen atoms hauv huab cua lossis cov kua yuav tsis tu ncua infiltrate lossis hlau atoms hauv cov hlau yuav tsis tu ncua sib cais, tsim cov hlau oxide, thiab cov hlau saum npoo yuav raug corroded tas li.
