Stainless hlau tau ntau dua thiab nrov dua nrog cov neeg vim nws cov kev txhim kho corrosion thiab qhov zoo ntawm qhov tsis yooj yim. Yog li dab tsi yog qhov sib txawv ntawm stainless hlau photovoltaic bolts thiab hlau bolts? Hnub no, cov editor yuav coj koj mus saib:
Ob lub txheej txheem steel thiab hlau ua tau los ntawm oxidation-txo cov kev xav, tab sis muaj qhov sib txawv ntawm cov khoom siv tshuaj tiv thaiv ntawm ob. Kev ua cov hlau yog los txo cov hlau, thaum hlau ua yog txo cov pa roj carbon ntau nyob rau hauv npua hlau thiab lwm yam Kev cuam tshuam yog muab tshem tawm. Yog li no, hlau thiab hlau tau qhov txawv txav los ntawm tus nqi ntawm cov ntsiab lus carbon. Cov hlau-carbon alloys nrog carbon cov ntsiab lus tsawg dua 2% yog hlau, thiab cov uas muaj carbon ntau dua 2% yog hu ua hlau. Yog li los ntawm metallurgical pom, tsis muaj ib qho kev ua kom zoo li cov hlau tsis huv.
Cov hlau tau siv dav vim tias nws qhov toughness, elasticity thiab nruj. Cov laj thawj feem ntau rau cov neeg siv khoom yuav yog tias cov hlau tsis xeb yuav tsis xeb, thiab seb tus qauv yuav nyiam los ntawm cov hlau nplaum. Raws li deb li xeb muaj kev txhawj xeeb, xeb txhais tau tias nws tsis muaj kev tiv thaiv corrosion. Lub ntsiab tseem ceeb uas txiav txim siab qhov kev txhim kho corrosion ntawm stainless hlau yog chromium. Hlau nrog chromium cov ntsiab lus saum toj no 10.5% yuav tsis xeb. Lub sijhawm no, qhov oxidation ntawm chromium thiab qhov nruab nrab yuav ua rau oxide zaj duab xis ntawm nws saum npoo, uas tuaj yeem tiv thaiv qhov kev txhim kho ntxiv.
