Cov khoom siv yooj yim thiab cov khoom

Lub ntsiab	Kev muaj pes tsawg leeg (%)
Chromium (cr)	18.0 – 20.0
Npib tsib caug (ni)	8.0 – 10.5
Carbon (c)	Tsawg dua los yog sib npaug rau 0. 08
Manganese (mn)	Tsawg dua los yog sib npaug rau 2. 0
Silicon (si)	Tsawg dua los yog sib npaug rau 1. 0
Phosphorus (p)	Tsawg dua los yog sib npaug rau 0. 045

Cov yam ntxwv tseem ceeb:

Corrosion Kuj: Ua kom oxidation, organic acids, thiab tshuaj khia ib puag ncig me me.

Ductility / Tofness: Tswj lub zog thiab yoog tau txawm tias tsis kub (tsis muaj lub tshuab ntsuas kub (tsis muaj lub zas-to-brittle transition).

Weldability: yooj yim welded siv cov txheej txheem ib txwm (Mig, laser), txawm tias tom qab Weld Annealing yuav xav tau.

Tsis muaj sib nqus: cov qauv sib nqus: cov qauv sib nqus ua rau nws tsis yog sib nqus hauv anealaled kev mob (tej zaum yuav ua me ntsis sib nqus tom qab ua haujlwm txias).

Cov txheej txheem tsim khoom

Welded yeeb nkab ntau:

Txoj kev sib sau: Cock Coils yog ib tsab, pluav, thiab tsim rau hauv ib qho cylindrical duab ntawm cov txiv hmab.

Vuam: npoo yog welded longitudinally siv TIG, ntshav, lossis qib siab tshaj plaws induction (HFI) vuam.

Sizing thiab xov: Welded yeeb nkab yog cov cua sov-kho (anealed kom ua tiav qhov ntev thiab pawm, zeb tiav, txhuam hniav, lossis daim iav polish).

Cov Ntawv Thov

Khoom Noj Khoom Haus & Dej Haus: Huv Leeg Tubing, Brewing Systems, ua mis nyuj ua.

Tshuaj lom neeg / petrochemical: roj thauj, kev sib pauv hluav taws xob, thiab cov raj hluav taws xob kub.

Architecture: Handrails, cov qauv kev coj ua, thiab cov loj hauv av.

Kev Kho Mob / Kws Tshuaj Siv Cov Khoom Siv Cua Zoo, Kev Siv Kom Huv Si.

Cryogenics: kua roj cia thiab thauj khoom (piv txwv li, lng, kua nitrogen).

Automotive: Tso cov pa tawm, roj kab (304L nyiam rau welded ntu).

Cov lus nug thiab cov lus teb uas nquag:

Q: Dab tsi yog 304Stainless hlau raj?

A:Qib 304: Austenitic stainless hlau, ib feem ntawm 300 series, paub rau nws corrosion

Q: Qhov twg yog qhov zoo dua, 321 lossis 304 ss?

A:Xaiv 304Yog tias:Tus nqi yog qhov tseem ceeb.Kev khiav hauj lwm kub nyob qis dua 500 degree.Tsis muaj kev pheej hmoo ntawm cov rhiab rhiab (piv txwv li, tsis muaj welded seem lossis post-weld annealing yog ua tau).

Xaiv 321Yog tias: qhov kub-kub ruaj khov (800-900 degree) yog cov rooj sib tham.Qhov kev sib tham yuav tsum muaj cov cua daj cua dub.

Q: Puas yog 304 stainless hlau yuav welded yooj yim?

A: Tau, 304 stainless hlau yogyooj yim weldedSiv cov hau kev (tig, mews, laser). Txawm li cas los xij, tsis txhob muaj cua sov ntau dhau los tiv thaivsiab zoo(Chromium Carbide Tsim). Kev siv304L(Cov pa roj carbon tsawg) lossis tom qab Weld annealing rau cov ntawv tseem ceeb.
