Dab tsi ntawm stainless hlau yog siv los ua fasteners?
Cov alloy muaj pes tsawg leeg thiab cov yam ntxwv ntawm cov hlau tsis xeb tau muab faib ua tsib pawg hauv qab no:
1. Austenitic stainless hlau
Nta: Muaj cov chromium siab thiab npib tsib xee, feem ntau kuj muaj me me ntawm molybdenum thiab nitrogen, nrog rau corrosion kuj zoo heev thiab toughness. Nws tsis tuaj yeem hardened los ntawm kev kho cua sov, tab sis tuaj yeem ua kom muaj zog los ntawm kev ua haujlwm txias.
Hom qauv: 304, 316, 317, thiab lwm yam.
Daim ntawv thov thaj chaw: tableware, khoom siv hauv chav ua noj, khoom siv tshuaj, kho kom zoo nkauj architectural, thiab lwm yam.
2. Ferritic stainless hlau
Nta: Cov ntsiab lus siab chromium (feem ntau 10.5-27%), cov ntsiab lus carbon tsawg, tsis muaj npib tsib xee, zoo corrosion kuj. Txawm hais tias nws yog nkig, nws yog tus nqi qis thiab muaj oxidation zoo.
Hom qauv: xws li 430, 409, thiab lwm yam.
Daim ntawv thov thaj chaw: feem ntau yog siv rau hauv tsheb tso tsheb, cov cuab yeej siv, khoom siv hauv tsev, kho kom zoo nkauj architectural, thiab lwm yam.
3. Martensitic Stainless hlau
Nta: Chromium cov ntsiab lus yog li 12-18%, thiab cov ntsiab lus carbon yog siab. Nws tuaj yeem ua kom tawv tawv los ntawm kev kho cua sov, thiab muaj lub zog siab thiab hnav tsis kam, tab sis nws cov corrosion kuj tsis zoo li austenitic thiab ferritic stainless hlau.
Hom qauv: xws li 410, 420, 440, thiab lwm yam.
Daim ntawv thov thaj chaw: riam, cuab yeej phais, li qub, bearings thiab lwm zaus uas yuav tsum tau muaj zog thiab hnav tsis kam.
4. Duplex Stainless Hlau
Nta: Nws muaj cov yam ntxwv ntawm ob qho tib si austenitic thiab ferritic stainless hlau, thiab ua tau zoo nyob rau hauv hardness kuj thiab corrosion kuj.
Hom qauv: xws li 2205, 2507, thiab lwm yam.
Daim ntawv thov thaj chaw: Ib puag ncig corrosive heev xws li marine engineering, tshuaj thiab roj av kev lag luam.
5. Cov nag lossis daus Hardening Stainless hlau
Nta: Lub zog siab dua tuaj yeem tau txais los ntawm kev kho cua sov, thiab zoo corrosion kuj. Cov khoom tseem ceeb yog chromium, npib tsib xee thiab tooj liab, nrog cov pa roj carbon tsawg.
Hom qauv: xws li 17-4PH, 15-5PH, thiab lwm yam.
Daim ntawv thov thaj chaw: aerospace, nuclear zog thiab lwm yam kev siv nrog lub zog siab.

Koj txoj kev thauj mus los yog dab tsi?
Peb muab cov kev thauj mus los hauv qab no rau koj xaiv los ntawm:
Kev thauj mus los hauv hiav txwv
Haum rau cov khoom siv ntau thiab kev thauj mus los ntev, nrog tus nqi qis thiab lub sijhawm thauj mus los ntev.
Tsheb thauj mus los
Haum rau cov khoom me me nrog lub sijhawm ua haujlwm siab, ceev ceev, tab sis tus nqi siab.
Kev thauj mus los hauv av
Feem ntau yog siv rau kev lag luam ntawm cov teb chaws nyob sib ze, haum rau kev thauj mus los nruab nrab thiab luv luv.
Tsheb thauj mus los
Feem ntau siv rau kev thauj mus los ntawm Tuam Tshoj thiab Europe, nrog lub sijhawm thiab tus nqi ntawm kev thauj mus los hauv hiav txwv thiab huab cua.
Kev xa khoom sai
Haum rau cov khoom me me ceev ceev, nrog tus nqi siab, tab sis kev xa khoom ceev ceev thiab yooj yim rau kev xa mus rau qhov rooj.
Txoj kev thauj mus los twg uas koj xaiv nyob ntawm koj hom khoom thauj, kev xav tau sijhawm thiab cov nqi siv nyiaj.
