Feem ntau cov hlau tsis muaj hlau poob rau hauv pawg no yog tsis yog-magneticvim tias lawv muaj ntau cov austenite. Txawm hais tias qee cov hlau zoo li qib 304 thiab 316 muaj hlau hauv lawv cov tshuaj muaj pes tsawg leeg, lawv yog austenite, txhais tau tias lawv tsis yog-ferromagnetic.
Yuav ua li cas cov hlau tsis muaj hlau nplaum?
Cov hom hauv qab no ntawm stainless hlau feem ntau yog sib nqus:
- Ferritic Stainless Steels xws li qib 409, 430 thiab 439.
- Martensitic Stainless hlau xws li qib 410, 420, 440.
- Duplex Stainless Hlau xws li qib 2205.
Cov hlau nplaum puas lo rau stainless hlau?
Cov hlau tsis nyiam tshaj plaws muaj cov khoom tsim zoo, tiv taus corrosion, thiab muaj zog. Txawm li cas los xij, nws tsis yog hlau nplaum vim nws yog alloyed nrog npib tsib xee, manganese, carbon, thiab nitrogen (austenitic).
Yuav lub hlau nplaum lo rau 430 stainless hlau?
A ferritic stainless zoo li 430 stainless hlau, ntawm qhov tod tes, yog ferromagnetic. Magnets stick to it. Tej zaum koj yuav pom cov hlau nplaum sib nqus uas yog 5-20% qis dua piv rau cov pa roj carbon tsawg.
Vim li cas qee cov hlau tsis muaj hlau nplaum?
Sib nqus thiab tsis-Magnetic Stainless Hlau
Txawm li cas los xij, cov hlau tsis zoo tshaj plaws yog 'austenitic' - cov no muaj cov ntsiab lus chromium siab dua thiab npib tsib xee kuj ntxiv. Nws yog npib tsib xee uas hloov kho lub cev qauv ntawm cov hlauthiab ua rau nws tsis yog-magnetic.
