Dab tsi yog sus316L stainless hlau lub ntsiab lus?

Sus316L Stainless Hlau - Lub ntsiab lus thiab cov khoom tseem ceeb

1. Lub ntsiab lus ntawm Sus316L

Sus:Cov tsiaj ntawv luv rau "Stainless Hlau" nyob rau hauv Japanese muaj cov qauv (JIS), ua haujlwm raws li tus qauv ua ntej rau cov qauv hlau stainless.

316:Qhia txog Austenitic steel hlau feem ntau ooysed nrog chromium (CR), npib tsib), thiab Molybdenum (mo). Nws sib haum rau AISI 316 hauv Asmeskas thiab en 1.440 hauv Tebchaws Europe.

L (cov ntshav tsawg):Kos npe rau cov ntsiab lus carbon qis (tsawg dua los yog sib npaug rau {{0}}}}}}. 03%, piv rau 0.08% hauv cov qauv 316). Qhov txo cov pa roj carbon tiv thaiv nag los nag lossis nag lossis kub ceev, yog li kev txhim kho kev tiv thaiv kev txhim kho.

2. Tshuaj lom neeg sib xyaw ntawm Sus316L(JIS G4303 Txuj Ci)

Lub ntsiab	C	Si	Mn	P	S	Cr	Ni	Mo
Zoo siab	Tsawg dua li lossis sib npaug rau 0. 03%	Tsawg dua los yog sib npaug rau 1. 0%	Tsawg dua los yog sib npaug rau 2. 0%	Tsawg dua los yog sib npaug rau 0. 045%	Tsawg dua li lossis sib npaug rau 0. 03%	16–18%	10–14%	2.0–3.0%

Molybdenum (2-3%):Tseem txhim kho corrosion tsis kam, tshwj xeeb tshaj yog tawm tsam chloride-muaj chaw ib puag ncig (piv txwv li, dej hiav txwv, ntsev cov kua, tshuaj lom roj ntsha). Muab kwv yees li peb zaug pitting thiab crevice corrosion tsis kam ntawm 304 stainless hlau.

Cov pa roj carbon (C tsawg dua lossis sib npaug rau 0. 03%):Tiv thaiv kev tsim ntawm cov carbes carbides thaum lub sij hawm vuam lossis kev pab kub siab, muaj txiaj ntsig mitigating intergranular corrosion. Qhov zoo tagnrho rau welded qauv xws li cov hlab siab siab thiab cov raj xa dej siab.

Ntiag tug	Tus nqi
Lub zog tensile	Ntau dua los yog sib npaug rau 480 MPa
Paib lub zog	Ntau dua los yog sib npaug rau 175 MPa
Hardness (HB)	Tsawg dua los yog sib npaug rau 187

4. Qhov Zoo ntawm Sus316L Stainless Hlau

Corrosion Kuj

Zoo heev rau nruab nrab-lub zog organic accicic acids muaj xws li sulfuric, phosphoric, thiab acetic acids.

Zoo tshaj plaws hauv chloride ib puag ncig (piv txwv li, tshav kub sib pauv hloov, pas dej tshuab), outtived), owperforming 304 stainless hlau.

Dhau los ntawm intergranular ntsuam xyuas hauv 10% oxalic acid daws (ib jis g0571) uas tsis muaj cim ntawm corrosion grooveses-zoo rau cov qauv welded.

Muaj zog

Muaj peev xwm ntxiv dag zog ntawm kev ua haujlwm txias (piv txwv li, txias kos duab, dov dej txias) thaum ua kom muaj weldability.

Er316L Vuam Hlau yog pom zoo kom tsis txhob muaj nag los nag lossis daus hauv cov chaw kub.

Txoj Kev Tu Huv Huv

Du saum npoo tiv thaiv scaling thiab paug; ua raws li FDA, 3A, thiab lwm cov qauv noj zaub mov.

Feem ntau siv nyob rau hauv cov khoom siv khoom lag luam muag khoom thiab cov chaw tso tsheb ua khoom noj cia.

5. Kev siv ntawm sus316L

Tshuaj lom neeg & petrochemical:Reactors, cov hlab ntsha siab, raj xa khoom rau tuav chloride lossis organic acid tawm.

Marine Engineering:Desalination systems, nkoj fittings-resistant rau ntsev tshuaj tsuag corrosion.

Khoom Noj & Kev Lag Luam Kho Mob:Kws Tshuaj Kho Mobile, Kev phais cov cuab yeej siv, cov tshuab thev naus laus zis.

Cov Ntawv Thov Kev Tsim Qauv:Nqaum tsev lub tsev ua pa, duab puab sab nraum zoov-zoo tshaj huab cua tiv thaiv rau 304.
