1, stainless hlau ntsia hlau yog hlau alloy, txhua chromium cov ntsiab lus ntawm ntau tshaj 12 feem pua. Chromium, nws yog ib hom kev tiv thaiv corrosion, yog li tag nrho cov stainless hlau muaj zog corrosion kuj. Feem ntau, qhov siab dua cov ntsiab lus ntawm chromium, qhov zoo dua corrosion kuj.
2, stainless hlau screws siv fasteners ntawm cov nickel ntsiab nyob rau hauv tus txheej txheem ntawm kev siv stainless hlau raws li cov khoom, ib zaug ntxiv cia siab rau kev siv cov nickel element, tab sis nyob rau hauv cov ntaub ntawv ntawm nickel element ntiaj teb no tus nqi, tus nqi ntawm fasteners yog cuam tshuam los ntawm lub loj dua. Fasteners ntau lawm lag luam thiaj li yuav txo tau lub siab ntawm peev, fasteners, kev sib tw muaj peev xwm, tshwj xeeb tshaj yog rau cov khoom hloov, zus tau tej cov nickel stainless hlau fasteners.
3, stainless hlau fasteners, yog siv stainless hlau ua cov khoom tseem ceeb ntawm cov ntsia hlau, yog kom paub txog cov hlau nplaum stainless hlau nws tus kheej. Stainless hlau feem ntau xav tias tsis muaj hlau nplaum, tab sis qhov tseeb austenite system kem cov khoom tom qab qee yam kev siv tshuab, yuav muaj qee yam sib nqus, tab sis yog tias qhov kev xav no yog sib nqus stainless hlau fastener tus qauv zoo tsis raug.
4, tag nrho cov hlau tsis muaj steel ntxiv nrog rau cov muaj pes tsawg leeg ntawm hlau thiab chromium, kuj muaj cov pa roj carbon. Tab sis cov ntsiab lus carbon tsawg heev thiab ua tib zoo tswj. Vim tias cov chromium thiab carbon tuaj yeem sib xyaw ua ke, tsim cov carbide, ua rau cov chromium Cheebtsam tiv thaiv corrosion ua me me heev. Yog li ntawd, txhawm rau kom ua tiav cov nyhuv anticorrosive, thaum cov ntsiab lus carbon nce, kom cov ntsiab lus ntawm chromium nce ntxiv.
