Ib qho: cov ntsiab lus ntawm cov ntsiab lus alloying, feem ntau hais lus, hlau nrog cov ntsiab lus chromium ntawm 10.5 feem pua ​​yog tsis yooj yim rau xeb. Qhov siab dua cov ntsiab lus ntawm chromium thiab npib tsib xee, qhov zoo dua corrosion kuj. Piv txwv li, cov ntsiab lus ntawm nickel hauv 304 cov khoom yog 8-10 feem pua, thiab cov ntsiab lus ntawm chromium yog 18-20 feem pua ​​. Xws li stainless hlau yuav tsis xeb nyob rau hauv ib txwm muaj xwm txheej.


Thib ob: cov txheej txheem smelting ntawm cov tuam txhab tsim khoom kuj tseem cuam tshuam rau corrosion kuj ntawm stainless hlau. Ib tsob ntoo loj stainless hlau nrog cov cuab yeej zoo smelting, cov cuab yeej siv siab heev thiab cov thev naus laus zis siab tuaj yeem ua kom tswj tau cov ntsiab lus alloying, tshem tawm cov impurities, thiab tswj cov cua txias ntawm lub billet, yog li cov khoom zoo yog ruaj khov thiab txhim khu kev qha, sab hauv. qhov zoo yog qhov zoo, thiab nws tsis yooj yim rau xeb. Ntawm qhov tsis sib xws, qee qhov me me steel mills muaj cov khoom siv rov qab thiab rov qab siv tshuab. Thaum lub sij hawm smelting txheej txheem, impurities tsis tuaj yeem raug tshem tawm, thiab cov khoom tsim tawm yuav inevitably xeb.


Thib peb: qhov chaw sab nraud, kev nyab xeeb yog qhuav thiab cua, thiab ib puag ncig tsis yooj yim rau xeb. Cov huab cua huab cua yog siab, huab cua tsis tu ncua los nag, lossis thaj chaw ib puag ncig uas muaj pH siab hauv huab cua yog qhov ua rau xeb. 304 stainless hlau, yog tias ib puag ncig ib puag ncig phem heev, nws yuav xeb.
