Kev faib tawm ntawm stainless hlau:
Nag lossis daus tawv tawv hlau
Nrog rau cov qauv zoo thiab weldability zoo, nws tuaj yeem siv los ua cov khoom siv zog ua kom muaj zog hauv kev lag luam nuclear, kev lag luam aviation thiab kev lag luam aerospace.
Nws muaj peev xwm raug faib ua CR system (400 Series), Cr Ni system (300 Series), Cr Mn Ni system (200 Series), kub tiv taus Cr alloy steel (500 Series) thiab nag lossis daus tawv (600 Series).
200 Series: Cr Mn Ni
201202 thiab hais txog: Manganese hloov ntawm nickel tsis zoo xeb tsis kam thiab yog siv dav ua qhov hloov pauv pheej yig rau 300 Series hauv Suav teb
300 tawm series: Cr Ni austenitic stainless hlau
301: ductility zoo, siv rau kev txhaj tshuaj molding khoom. Nws kuj tseem tuaj yeem ua khoom tawv sai sai los ntawm kev siv lub tshuab. Zoo weldability. Cov coj tsis kam thiab nkees lub zog zoo dua li 304 stainless hlau.
302: qhov tsis kam tiv thaiv corrosion yog tib yam li 304, vim tias cov pa roj carbon ntau cov ntsiab lus, lub zog zoo dua.
303: los ntawm kev ntxiv me me ntawm cov leej faj thiab phosphorus, nws yooj yim rau kev txiav dua 304.
304: qauv hom phiaj dav dav; piv txwv li 18/8 steel hlau. Cov khoom lag luam xws li: corrosion resistant ntim, rooj noj mov, rooj tog zaum, tsheb nqaj hlau, khoom siv kho mob. Cov qauv txheem yog 18% chromium thiab 8% npib tsib xee. Nws yog cov hlau nplaum tsis muaj hlau uas nws cov qauv hlau tsis tuaj yeem hloov los ntawm kev kho cua sov. GB qib yog 06cr19ni10.
304 L: cov yam ntxwv zoo ib yam li 304, tab sis cov pa roj carbon tsawg, yog li nws muaj kev xeb ntau dua, yooj yim rau kev kho cua sov, tab sis cov khoom siv tsis zoo, haum rau vuam thiab tsis yooj yim rau cov khoom siv kho cua sov.
304 n: nws yog hom ntawm stainless hlau muaj nitrogen nrog cov yam ntxwv ntawm 304. Lub hom phiaj ntawm ntxiv nitrogen yog txhawm rau txhim kho lub zog ntawm cov hlau.
309: nws muaj kev kub zoo tshaj li 304, thiab qhov kub thiab txias tsis txaus yog li 980 ℃.
309 s: nrog ntau ntawm cov chromium thiab npib tsib xee, nws muaj qhov ua tau zoo tiv thaiv tshav kub thiab oxidation tsis kam, xws li cov cua kub ua kom sov, boiler Cheebtsam thiab lub cav txhaj tshuaj.
310: zoo heev kub-oxidation tsis kam, qhov siab tshaj plaws siv kub ntawm 1200 ℃.
316: tom qab 304, qhov thib ob feem ntau siv cov qib steel yog siv dav hauv kev lag luam khoom noj khoom haus, saib thiab thawb moos, chaw tsim tshuaj lag luam thiab khoom siv phais. Ntxiv molybdenum keeb ua rau nws tau txais tshwj xeeb los tiv thaiv xeb. Vim tias nws qhov kev cuam tshuam zoo rau chloride corrosion dua li 304, nws kuj yog siv ua "marine steel". SS316 feem ntau yog siv hauv cov khoom siv hluav taws xob rov qab nuclear. Qib 18/10 stainless hlau feem ntau ua tau raws li qib thov no.
316L: cov pa roj carbon tsawg, yog li nws muaj kev xeb ntau dua thiab yooj yim rau kev kho cua sov. Cov khoom lag luam xws li cov cuab yeej siv tshuaj ntxuav khoom, tshuab hluav taws xob tua hluav taws xob, tub yees cia.
321: lwm yam khoom zoo ib yam li 304 tsuas yog tias qhov kev pheej hmoo ntawm weld corrosion yog txo vim qhov txuas ntxiv ntawm titanium.
347: ntxiv cov khoom siv khov kho niobium, haum rau vuam aviation twj siv hauv tshuab thiab cov cuab yeej siv tshuaj.
400 series: Ferritic thiab martensitic stainless hlau, manganese dawb, tuaj yeem hloov 304 stainless hlau rau qee yam
408: zoo kub ua hauj, tsis muaj zog corrosion tsis kam, 11% Cr, 8% Ni.
409: tus qauv pheej yig tshaj plaws (Tebchaws Askiv thiab Asmeskas), feem ntau yog siv los ua tsheb tso pa ntawm cov yeeb nkab, belongs rau ferritic stainless hlau (chromium steel).
410: martensite (lub zog siab muaj zog chromium steel), zoo hnav tsis kam, tsis kam corrosion.
416: kev ntxiv cov leej faj ntxiv txhim kho cov txheej txheem tuaj ntawm cov khoom.
420: "txiav twj qeb" martensitic steel, zoo ib yam li Brinell siab chromium steel, hlau ua ntej tshaj plaws. Nws kuj tseem siv rau riam phais. Nws ci ntsa iab heev.
430: ferritic stainless hlau, kho kom zoo nkauj, piv txwv li, khoom siv kho tsheb. Kev ua kom zoo, tab sis kev ua haujlwm tsis zoo kub thiab kev tiv thaiv corrosion.
440: lub zog siab txiav cov cuab yeej steel, nrog cov pa roj carbon ntau dua me me, tuaj yeem tau txais cov khoom muaj zog ntau dua tom qab kev kho kom sov, thiab lub siab tuaj yeem ncav cuag 58hrc, uas yog ntawm cov hlau tsis muaj qhov nyuaj. Feem ntau cov ntawv thov piv txwv yog "chais plaub". Muaj peb hom qauv sib xws: 440A, 440b, 440C, thiab 440f (yooj yim rau cov txheej txheem).
500 Series: kub tiv thaiv chromium alloy steel.
600 Series: Martensite Kev Nyab Xeeb Hardening Stainless hlau.
Stainless hlau mesh
Vijtsam stainless hlau tseem hu ua kev tshuaj ntsuam stainless hlau lim vim tias nws yog siv rau kev lim cov khoom lag luam.
Cov khoom siv: SUS201, 202, 302, 304, 316, 304L, 316L, 321 stainless hlau xaim, thiab lwm yam.
