AISI 304: kev yam ntxwv. stainless steel

AISI 304 specifications uas koj yuav nrhiav tau nyob rau hauv tsab xov xwm, yog ib tug saib ntawm lub ntsiab ntau yam ntawm tsev neeg ntawm stainless steels. Qhov no cov ntaub ntawv uas - austenitic steel nrog haum uas tsis muaj cov ntsiab lus. Thaum familiarized nrog lub xeev cov qauv, uas yog siv nyob rau hauv Russia, koj yuav to taub hais tias raws li ib tug counterpart mus rau dej siab steel qib 08H18N10.

Piav cov ntaub ntawv uas yog acid-resistant, nyob rau hauv tas li ntawd, nws muaj peev xwm nyiaj mus dhau luv luv-term raug kub txog li 900 ^o C. Tab sis cov no yus nta yog tsis tus tsuas yog sawv daws yuav uas mloog yuav tsum tau them, muaj ntau yam ntawm lawv, yuav tsum tau pes tsawg, tsau, thiab yuav tsum tau tham hauv qab no.

kev yam ntxwv

AISI 304 specifications uas yuav tsum tau nyeem ua ntej mus rau lub tshaaj, muaj ib tug ntom nyob rau hauv cov kab kev los ntawm 7.9 mus 7,93 g / cm ^3. Tensile zog yog 505 MPa, thaum lub sij hawm tawm los kev nyuaj siab yog 215 MPa. Vickers hardness yog 129, Knoop hardness yog 138. Yog hais tias koj yog ib tug private neeg siv, koj yuav tsum xyuam xim rau cov conformity ntawm cov khoom GOST.

AISI 304 specifications uas yuav pab tau koj ua tus xaiv txoj, muaj ib tug plasticity nyob rau theem ntawm 70%. Qhov no yog muaj tseeb yog hais tias tus phaj thickness yog 50 mm. Lub modulus ntawm elasticity ntawm cov khoom yog hom twg los ntawm 193 rau 200 GPA. Lub shear modulus yog 86 GPA. Thaum chav tsev kub, lub magnetic permeability yog 1.008. Hluav taws xob cov kuj yog cov kev txwv 7.2e-005 ohm-cm, uas yog qhov tseeb rau ib tug kub ntawm 20 ° ^C. Qhov no qhov chaw yog hloov mus rau 1.16E-04, yog hais tias tus kub ntawm lub nce mus 650 ° ^C.

Muaj ntau cov kev pab yog xav paub ntxiv txog thaum tshav kub kub thiab, nyob rau hauv cov ntaub ntawv no, nws yog 0.5 kJ / (g · K). Tej zaum koj yuav xav ntau thiab ib tug melting sov li, nws mas nws txawv nyob rau hauv ntau ntawm 1400 mus 1455 ^C. Lub thermal conductivity ntawm cov ntaub ntawv uas yog 16.2 W / (m · K).

Cov yooj yim daim ntawv thov thiab tej zog

AISI 304, yam ntxwv ntawm cov uas tau hais saum toj no yog siv nyob rau hauv qhuav ntawm chaw dim pa thiab cov pa luam yeeb, raws li zoo raws li flues. Zoo heev cov ntaub ntawv uas muaj pov thawj nyob rau hauv qhov siv thiab ua cov khoom rau cov cia, ntau lawm thiab thauj caw, npias, mis nyuj thiab lwm yam dej raws li cov tshuaj. Steel yog siv nyob rau hauv qhov siv thiab ua cov khoom rau cov khoom noj thiab tshuaj industries, raws li zoo raws li catering tsim.

Nrog nws ua noj chav thiab chav tsev mov, raws li tau zoo raws li kav rau txawv hom phiaj. Ntau rests hlau thiab lub hauv paus ntsiab ntawm lub architecture. Sheet AISI 304 - ib cov khoom uas nruab nrab yog cov yooj yim qib ntawm tsev neeg ntawm stainless steels. Ntxiv cov khoom xyaw uas muaj Cr, uas nws muaj pes tsawg leeg yuav tsum muaj tsawg kawg yog 18%. Nrog rau kev hwm mus Ni, nws ntim luj yog 10%. Xws li ib tug cov ntsiab lus ntawm cov thawj ntawm hais tias cov khoom xyaw ua rau tsim rau ntawm qhov chaw ntawm lub oxide txheej, nws muab cov ntaub ntawv uas ib tug tsis kam rau ntau yam tshuaj. Qhov no piv txog lub ntsiab nyob rau hauv muaj pes tsawg leeg ua tau rau ib ce muaj zog antiferromagnetically zog.

Cov ntaub ntawv nyob rau hauv nyob tus yeees ntawm

AISI 304 stainless steel ntawv ib feem muaj xws li, raws li twb tau piav saum toj no los ntawm Cr, uas yog muaj nyob rau hauv muaj pes tsawg leeg yuav thaj tsam li ntawm 18 mus rau 20%. Hais txog C, ces nws siab tshaj plaws cov ntsiab lus yog 0.08%. Fe tej zaum yuav muaj nyob rau hauv cov ntaub ntawv uas nyob rau hauv tus nqi ntawm cov 66,345 rau 74%, txoj kev Mn, ces nws muaj li ntawm ib tug tshaj plaws ntawm cov 2%. Ni nyob rau hauv daim ntawv muaj los ntawm 8 rau 10.5%, kev xav txog P thiab S, cov khoom muaj nyob rau hauv lawv cov nyiaj pab ntau tshaj 0,045-0,03%, ntsig txog.

hauj lwm steel

Piav nyob rau hauv tsab xov xwm hom pom nws kis nyob rau hauv qhov siv thiab ua welded thiab prefabricated hlau, tsev neeg cov khoom thiab yam pipeline fittings. Yog hais tias mention hauv daim ntawv ntawm ib daim ntawv, lub steel yuav txwv kom muab zais rau hauv kub-Kuav los tiag thiab txias-dov khoom, raws li txiav txim los ntawm lub ntau lawm tshuab. Pav ca hlau yog pom tau hais nyob rau hauv daim ntawv ntawm qaws thiab los xij. Lub nto ntawm lub web nyob rau hauv cov txheej txheem yuav tsum kho nyob rau hauv ib txoj kev raws li ib tug tshwm sim muaj peev xwm muab tau nram qab no variations ntawm cov saum npoo:

• daim iav;
• polished;
• matt.

Ntawm kev muag khoom tshwm sim stainless yeeb nkab, uas yog ua los ntawm hluav taws xob-txoj kev. Cov khoom no tsis yog raug rau corrosion nyob rau cov chaw uas cov neeg kho tshuab kev puas tsuaj los yog khawb raug tsim. Ntim ua los ntawm no steel yuav siv tau rau thauj thiab cia ntawm cov khoom ntawm cov tshuaj ua lag luam, cov lag luam ua noj. Nyob rau hauv thawj cov ntaub ntawv peb yuav tau tham txog cov tsis muaj zog tshuaj.

Lub raj-zoo li tus hlau tej zaum yuav muaj ib tug rectangular, yeej los yog square ntoo khaub lig-section. Nyob rau hauv txoj kev uas ua cov khoom no yuav tsum seamless los yog electrofusion. Lub nto nyob rau hauv cov neeg mob yuav tsum polished, brushed los yog daim iav. AISI 304 (GOST 08H18N10) yog siv rau qhov siv thiab ua casks rau plaub, kvass thiab npias, raws li zoo raws li cov khoom rau cov ntau lawm, txias coils, qoob, khoom noj siv mis khoom, cryogenic hlab ntsha, evaporators, pans.

Cov khoom ntawm cov yeeb nkab steel AISI 304

Los ntawm cov ntaub ntawv uas tau piav nyob rau hauv tsab xov xwm ua stainless raj, uas muaj tib lub specifications li cov tau piav saum toj no. Cov khoom uas siv rau tso pipelines vim hais tias kev sib txuas lus nyob rau hauv cov ntaub ntawv no muaj tsis smoothness, corrosion kuj, tsis txhob sau rau hauv tshuaj tshua nrog rau lwm yam tshuaj thiab muaj lub peev xwm mus kho nws tus kheej yog puas ntsoog.

Cov kav dej tsis muaj deformations thiab irregularities, lawv muaj ib tug txheej ntawm chromium oxide, uas muab kam mus rau lub sab nraud ib puag ncig. Cov khoom muaj zoo lub zog, lawv txais lawv tus kheej txig welded, muaj ib tug high degree ntawm ua yooj yim thiab kuj kub. Tag nrho cov yooj yim zoo khaws cia txawm nyob rau hauv tej yam kev mob ntawm huab tsis muaj peevxwm. Cov khoom uas muaj yus ib tug ntev-lub neej, yooj yim ntawm installation thiab yooj yim ntawm installation.

Scope stainless yeeb nkab

Stainless hlau yeeb nkab pom nws kis yuav luag qhov txhia chaw. Nws muaj ib tug txaus nyiam cov tsos, uas enables stacking nyob rau hauv tej cheeb tsam. stainless steel yeeb nkab yuav siv tau los ua ntseej, railings thiab stairs, welded thiab prefabricated hlau, ntawm no muaj xws li lub thiab square hlab, thiab Profiled khoom. Tej kav dej uas siv rau tso lub raj dej ntawm ib qho tseem ceeb thaj chaw, lawv yuav ua ib feem ntawm koj lub tsheb tus tso system, thiab siv nyob rau hauv qhov siv thiab ua cov pa tso Cheebtsam thiab lub raj.

Hauj lwm Stainless hlau luj tshib

Lub luj tshib AISI 304 kuj yuav muaj nyob rau hauv kev ua lag luam niaj hnub no. Lawv yuav tau tag nrho cov hom ntawm cov hniav, uas muaj tau hais saum toj no nyob rau hauv brashtovannaya nto yog siv raws li ib tug ntxiv embodiment. Lub ub tej zaum yuav pa, los yog elongated. Lawv ua raws li tus qauv thiab muaj ib tug fillet voos kheej-kheej nyob rau hauv ntau ntawm 1.5 inch zaj. Lub phab ntsa thickness yuav thaj tsam li ntawm 1 mus rau 9 hli thaum lub sij hawm txoj kab uas hla yog sib npaug zos rau cov duab ntawm 12 mus rau 406 hli.

Hauj lwm Stainless hlau hlau

AISI Hlau 304 yog ua nyob rau hauv raws li thoob ntiaj teb cov qauv, qhov luaj li cas ntau yuav sib txawv ntawm 1.5 mus rau 10 hli. Koj muaj peev xwm yuav cov khoom sib txawv ntawm cov hardness, thaum nws los txog rau mos ntau ntau yam, nyob rau hauv cov ntaub ntawv no nws yog 500 N / mm². Yog hais tias qhov kev kawm, ib tug hlau yuav tsum tau muas caij nplooj ntoos hlav nruj nyob rau hauv cov ntaub ntawv no nws yuav tsiag ntawv los ntawm cov hauv qab no ntau ntau cov no parameter yog 1400 N / mm².

Cov kev kho mob tej zaum yuav loj nrog ib matte los yog daim iav. Hlau siv nyob rau hauv khoom noj khoom haus kev lag luam, kev tsim kho, tshuaj thiab kws industries. Nws yuav siv tau nyob rau hauv qhov siv thiab ua lub tsev lug, electrodes, springs, hniav nyiaj hniav kub thiab khob iav.

xaus

Stainless hlau tau pom nws ntau tis, nws yog nyob rau hauv coob cov zoo tib yam tau txais kev pab thiab cov tub txawg, vim hais tias cov khoom yog universal. Nws muaj koj xeb kuj ua tau zoo raws li zoo raws li oxidation. Nws ntseg zoo heev weldability thiab muaj zoo heev uas tsis muaj kub zog.
