Stainless hlau yog cov khoom siv uas tau hloov kho peb cov ntawv thov hauv tsev hauv tsev thiab kev lag luam. Nws muaj qhov txaus siab, lub zog, thiab corrosion tsis kam uas yog vim li cas nws thiaj pom nyob rau hauv txhua yam ntawm cutly riam rau skyscrapers. Tab sis dab tsi raws nraim yog stainless hlau?
Cia peb tham txog txhua cov ntsiab lus ntawm cov alloy no, suav nrog nws cov hom, cov chav kawm, thiab ua tau.
Ib tug txheej txheem cej luam.
Stainless hlau yog qeb ntawm cov hlau. Cov alloy muaj tsawg kawg yog 10.5% chromium hauv nws cov muaj pes tsawg leeg, thiab koj tuaj yeem ntxiv lwm cov ntsiab lus xws li npib tsib xee, thiab titanium kom txhim kho nws cov khoom. Qhov no muab nws siab tiv taus corrosion, xeb, thiab staining.
Lawv qhia cov khoom zoo li lub zog, durability, thiab kev tiv thaiv kom sov thiab hnav hauv cov khoom siv.
Stainless hlau los nyob rau ntau hom, series, thiab qib. Peb yuav tham lawv hauv qab no.
Cov hom stainless hlau.
Cov khoom siv no tuaj yeem muab faib ua ntau hom ntawm nws txoj kev muaj pes tsawg leeg:
1. Austenicic.
Qhov no yog feem ntau siv hom stainless hlau, thiab nws muaj chromium, npib tsib xee, thiab molybdenum. Koj yuav pom tias nws tsis yog-sib nqus thiab tiv taus kev xeb, xeb, thiab staining. Raws li ib tug tshwm sim, koj tuaj yeem siv tshuaj tsis huv stainless hlau nyob rau hauv cov ntawv thov rhiab, xws li kev cog hniav.
Cov kabmob no muaj cov weldability zoo thiab ua npuas ncauj thiab siv nyob rau hauv ntau yam kev siv, xws li khoom siv kho mob, thiab khoom siv kho mob, thiab khoom siv kho mob, thiab cov qauv kws kos duab.
2. Ferritic.
Pawg no muaj cov alloys muaj kev muaj siab ntawm cov chromium thiab qhov qis qis dua ntawm npib tsib xee. Nws yog ruaj khov tiv thaiv cov tshuaj lom neeg thiab cua sov, yog li nws tau siv hauv cov ntawv thov kom muaj kev hloov cua sov, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob.
Cov hlau ferritic sterritic sib nqus tau sib nqus, qhia kom meej lawv siv hauv cov ntawv thov uas cov magnetic muaj txiaj ntsig, xws li cov hloov hluav taws xob thiab hluav taws xob.
3. Martenitic.
Cov hlau no yog tsiag ntawv los ntawm lawv cov qib carbon ntau qib thiab qib qis dua qib, muab lub zog zoo tshaj. Txawm li cas los xij, qhov no ua rau lawv tsis muaj kev pab rau corrosion dua li lwm hom hlau stainless, tshwj xeeb tshaj yog nyob rau hauv acidic ib puag ncig.
Martensitic Stainless hlau kuj tseem tsawg dua cov cua sov dua li cov hlau. Vim yog lawv cov tshuaj tiv thaiv nyuaj thiab ntau yam tshuaj ruaj khov, koj feem ntau yuav pom lawv hauv cov cuab yeej, riam, thiab lwm yam ntse.
4. Duplex.
Alloys hauv pawg no tau paub txog lawv cov hardness zoo heev thiab corrosion tsis kam. Lawv muaj yuav luag sib npaug ntawm cov ustenitic thiab ferritic theem- kev sib xyaw ua ke uas ua rau lawv ruaj khov heev.
Koj yuav pom cov steels zoo rau cov ntawv thov uas yuav tsum muaj zog, xws li roj thiab roj ua khoom siv, thiab tawm ntawm ntug kev.
5. Naintitation-hardening stainless hlau.
Pawg no muaj cov alloys nrog qib siab ntawm cov chromium, npib tsib xee, ua rau lawv muaj zog, thiab tiv taus cov neeg sawv cev corrosive. Vim nws lub zog siab, PH qhov hlau feem ntau siv hauv aerospace thiab lwm cov ntawv thov uas xav tau.
Stainless Hlau Series
Cov hlau stainless kuj tau muab cais rau hauv cov koob sib txawv; Cia peb tham txog cov qauv.
200 stainless hlau series:
Hloov chaw npib tsib xee, cov koob no ua rau siv cov kev xav ntawm manganese siab. Qhov no ua rau lawv pheej yig dua. Koj yuav pom 200 series hauv kev ua khoom noj thiab kev lag luam automotive.
300 Stainless Hlau Series:
Cov koob no muaj qib tsib xee, ua rau nws cov qhab nia muaj kev tiv thaiv zoo. Lawv tau siv nyob rau hauv ntau daim ntawv thov, xws li cov qauv vajtsev txua khoom thiab cov khoom siv kho mob.
400 stainless hlau series:
Cov txheej txheem 400 series muaj cov pa roj carbon ntau, tab sis lawv tsis tshua muaj kev txhim kho. Lawv feem ntau siv rau hauv riam thiab lwm yam khoom ntse.
500 stainless hlau:
Cov ntaub ntawv hauv cov series no muaj ntau ntau cov chromium thiab molybdenum ntxiv rau lawv. Lawv yog qhov kub kub tiv taus thiab siv hauv txoj hlab hlau thiab hluav taws kub.
600 Stainless Series:
Cov kawm qib no yog ob qho kub thiab corrosion-resistant. Lawv pom nyob hauv cov roj av roj thiab ua cov cuab yeej siv.
Yuav ua lag luam Stainless
Ntawm no yog ib qho kev qhia txog kev tsim khoom lag luam.
Melting thiab Refining: Ua ntej, koj yaj thiab ua kom zoo cov khoom siv raw. Cov no suav nrog hlau, npib tsib xee, chromium, thiab lwm yam alloying ntsiab, uas tau melted nyob rau hauv lub cub tawg thiab kho kom tshem tawm impurities.
Casting: Thaum cov khoom siv tau melted thiab ua kom zoo, koj tau pov rau hauv kev haus lossis billets.
Dov Kub Cov flatten no thiab cov duab lawv mus rau hauv daim ntawv xav tau, xws li cov nplooj ntawv, tuav, lossis coils.
Colding txias: Tom qab kub dov, koj yuav tsum txias-yob cov hlau. Koj ua qhov no los ntawm kev dhau cov khoom los ntawm ntau yam ntawm txias dov tom qab. Qhov no cov duab nws puab puab ntxiv.
Annealing thiab pickling: koj kho tus co-rolled steel los ntawm cua sov nws mus rau qhov kub thiab txias nws qeeb. Qhov no txhim kho cov khoom siv ductility thiab lub zog.
Koj ces pickle koj alloy thiab kho nws cov kua qaub kom tshem tawm cov impurities thiab txhim kho nws cov npoo ua tiav.
Xov: Qhov no cuam tshuam ntau cov txheej txheem los muab cov khoom siv kawg thiab cov npoo ua tiav.
Qhov no suav nrog kev txiav, polishing, lossis lwm cov tswv yim, nyob ntawm daim ntawv thov thiab npaj siv ntawm stainless hlau.
Yam cuam tshuam rau qhov zoo ntawm stainless hlau
Qhov zoo tshaj ntawm stainless hlau yog cuam tshuam los ntawm ntau yam, suav nrog cov khoom siv site, kev tsim khoom, thiab kev kho tiav.
Cov khoom siv Sourcing: Qhov zoo ntawm cov hlau tsis muaj roj ntau zaus nyob ntawm qhov zoo ntawm nws cov khoom siv raw - lub purity ntawm cov hlau.
Cov txheej txheem tsim khoom: Raws li peb pom, kev tsim khoom ntawm cov hlau muaj ntau cov kauj ruam, suav nrog melting thiab rolling, capting, pickling, thiab xov. Koj yuav tsum ua tib zoo tswj tau tag nrho cov kauj ruam no kom ntseeg tau tias cov stainless hlau muaj qhov xav tau zoo.
Cov txheej txheem ua tiav: kev ua tiav yog ib qho tseem ceeb hauv kev ua cov hlau zoo stainless hlau.
Koj yuav tsum ua tiav cov txheej txheem ua tiav xws li txiav, polishing, thiab buffing kom zoo kom tsis txhob ua rau muaj kev puas tsuaj ntawm koj lub taub hau.
Kev kho deg: kev kho mob xws li hmoov hmoov, electropolishing, thiab ua rau nws tiv taus corrosion thiab lwm yam kev hnav thiab kua muag.
Yuav ua li cas Stainless Hlau piv nrog lwm cov ntaub ntawv?
Ntawm no yog li cas no alloy ua tawm tsam qee cov ntaub ntawv:
Stainless vs. Carbon Steel
Thaum muab piv rau cov hlau hlau, hlau Stainless yog ntau ntau corrosion-resistant. Nws tau siv rau cov pa roj carbon hlau nyob rau hauv ib puag ncig. Stainless hlau kuj tseem ntau dua cov tub rog hlau, uas ua rau nws tiv taus ntau dua hauv kev ua haujlwm xav tau.
