1. Ferritic stainless hlau
Chromium cov ntsiab lus yog 15% ~ 30 feem pua. Nws cov corrosion kuj, toughness thiab weldability nce nrog nce cov ntsiab lus chromium. Nws cov chloride kev nyuaj siab corrosion kuj yog superior rau lwm hom stainless hlau. Nrog cov ntsiab lus chromium siab, nws cov kev tiv thaiv corrosion thiab oxidation kuj zoo, tab sis nws cov khoom siv tshuab thiab thev naus laus zis tsis zoo. Nws feem ntau yog siv rau cov qauv acid resistant nrog me ntsis kev nyuaj siab thiab oxidation resistant steel.
Daim ntawv thov: Nws yog siv rau nitric acid thiab khoom noj khoom haus Hoobkas khoom, thiab kuj yuav siv tau los ua qhov chaw ua hauj lwm nyob rau hauv kub kub, xws li roj turbine qhov chaw.
2. Austenitic stainless hlau
Chromium cov ntsiab lus yog ntau tshaj 18 feem pua, thiab nws kuj muaj li ntawm 8 feem pua nickel thiab ib tug me me ntawm molybdenum, titanium, nitrogen thiab lwm yam khoom. Nws muaj kev ua haujlwm zoo thiab tuaj yeem tiv thaiv corrosion ntawm ntau yam nruab nrab. Cov qib zoo ntawm austenitic stainless hlau muaj xws li 1Cr18Ni9, 0Cr19Ni9, thiab lwm yam. Cov hlau no muaj cov yas zoo, toughness, weldability, corrosion resistance thiab non-magnetic los yog tsis muaj zog magnetic zog. Nws muaj kev tiv thaiv corrosion zoo hauv oxidizing thiab txo cov xov xwm.
Daim ntawv thov: Nws yog siv los ua cov khoom siv tiv thaiv acid, xws li cov khoom siv tiv thaiv corrosion thiab cov khoom siv hauv ob sab phlu, xa cov kav dej, cov khoom siv nitric acid resistant, thiab lwm yam, thiab tseem tuaj yeem siv los ua cov khoom tseem ceeb ntawm stainless hlau moos accessories.
3. Austenitic ferritic duplex stainless hlau
Ib tug stainless hlau nyob rau hauv uas cov qauv austenite thiab ferrite suav txog li ib nrab ntawm ib leeg. Nws muaj ntau dua plasticity thiab toughness, tsis muaj chav kub brittleness, ho txhim kho intergranular corrosion kuj thiab vuam kev ua tau zoo, thaum tuav lub 475 degree brittleness ntawm ferritic stainless hlau, siab thermal conductivity, superplasticity thiab lwm yam ntxwv.
Daim ntawv thov: Nws cov cuab yeej zoo tshaj plaws thiab kev tiv thaiv corrosion tau yeej qhov kev nyiam ntawm cov neeg siv, thiab nws tau dhau los ua cov khoom siv hluav taws xob zoo heev uas tuaj yeem txuag tau qhov hnyav thiab peev.
4. nag lossis daus hardening stainless hlau
Lub matrix yog austenitic los yog martensitic, thiab cov qib ntawm nag lossis daus hardening stainless hlau yog 04Cr13Ni8Mo2Al, thiab lwm yam Stainless hlau uas tuaj yeem hardened (strengthened) los ntawm nag lossis daus hardening (tseem hu ua hnub nyoog hardening).
Daim Ntawv Thov: Siv dav hauv kev lag luam thiab kev lag luam hauv kev lag luam, xws li cov nag lossis daus hardening stainless hlau 17-4P, uas tuaj yeem siv los ua cov qauv nrog corrosion kuj, hnav tsis kam thiab siab zog hauv qab 370 degree
5. Martensitic stainless hlau
Siab zog, tab sis tsis zoo plasticity thiab weldability. Cov hom ntawm martensitic stainless hlau yog 1Cr13, 3Cr13, thiab lwm yam. Vim nws cov ntsiab lus carbon siab, nws muaj lub zog siab, hardness thiab hnav tsis kam, tab sis nws cov corrosion kuj me ntsis.
Lub hom phiaj: Nws yog siv rau qee qhov chaw uas muaj cov cuab yeej cuab tam siab thiab cov kev xav tau ntawm kev tiv thaiv corrosion, xws li springs, turbine blades, hydraulic li qub, thiab lwm yam. Cov hlau no yog siv tom qab quenching thiab tempering. Annealing yuav tsum tau tom qab forging thiab stamping.
6. Stainless hlau daim hlau thiab strips rau cov khoom siv siab
Kev faib tawm thiab kev cai, qhov loj me, cov duab thiab qhov sib txawv ntawm qhov tso cai, kev xav tau, kev sim, kev tshuaj xyuas, kev ntim khoom, cov cim thiab cov khoom pov thawj zoo ntawm cov hlau tsis muaj steel rau cov hlab ntsha muaj qhov xav tau meej. Cov hom muaj xws li 06Cr19Ni10, 022Cr17Ni12Mo2, thiab tus lej code yog S30408, S31603, thiab lwm yam.
Daim ntawv thov: Feem ntau yog siv rau cov khoom noj khoom haus, tshuaj machinery thiab lwm yam khoom siv huv.
