Dab tsi yog austenitic stainless hlau?

Nws yog ib hom tshwj xeeb ntawm stainless hlau alloy. Nws yog tus cwj pwm los ntawm cov ntsiab lus siab ntawm chromium thiab npib tsib xee. Austenitic steel yog tsis-sib nqus thiab muaj qhov zoo tshaj plaws vuam thiab formability zog.

Dab tsi yog cov khoom ntawm austenitic stainless hlau?

Nws yog chromium-nickel alloy uas muaj kwv yees li 18% chromium thiab 8% npib tsib xee. Lawv tsis yog hlau nplaum thiab muaj kev tiv thaiv corrosion ntau dua li lwm yam hom stainless hlau. Austenitic stainless hlau kuj tsis tshua muaj qhov ua rau nkig ntawm qhov kub thiab txias.

Dab tsi yog cov yam ntxwv ntawm austenitic stainless hlau?

Nws yog ib hom tshwj xeeb ntawm stainless hlau alloy nrog cov ntsiab lus siab ntawm chromium thiab npib tsib xee. Piv rau lwm hom stainless hlau, lawv muaj cov ntsiab lus qis dua, uas ua rau lawv zoo heev tiv thaiv intergranular corrosion. Austenitic steel kuj muaj zoo formability thiab weldability.

Qee yam tseem ceeb muaj xws li:

• High corrosion tsis kam
• High ductility thiab toughness
• Cov qauv zoo thiab weldability
• Kev ua tau zoo ntawm qhov kub thiab txias

Dab tsi yog cov ntawv thov ntawm austenitic stainless hlau?

Nws yog hom kev siv ntau tshaj plaws ntawm stainless hlau. Lawv yog cov chromium-nickel alloys nrog cov ntsiab lus chromium xws li 16% mus rau 30% thiab cov ntsiab lus npib tsib xee txog li 35%. Lawv paub txog lawv zoo heev corrosion kuj thiab zoo mechanical zog.

Qee cov ntawv thov siv xws li:

• Cov khoom siv ua zaub mov
• Cov dab dej thiab cov chaw ua haujlwm
• Chemical cia tanks
• Cov hlab ntsha siab
• Aerospace Cheebtsam

Ntxiv txog qhov kev siv ntawm austenitic stainless hlau:

Austenitic 304 stainless hlau phaj yog ib yam khoom uas raug liam tias muaj zog xeb thiab corrosion kuj, zoo heev plasticity thiab toughness, thiab yog ib qho yooj yim rau stamp thiab daim ntawv. Nrog rau qhov ceev ntawm 7.93 g / cm³, 304 stainless hlau yog hom stainless hlau ntau heev, tseem hu ua 18/8 stainless hlau hauv kev lag luam. Nws cov khoom siv hlau yog kub-resistant thiab muaj cov khoom zoo machining, ua rau lawv siv dav hauv kev lag luam xws li rooj tog thiab kho kom zoo nkauj kev lag luam, zaub mov thiab kev lag luam kho mob.

Kev tsim khoom ntawm Austenitic Stainless Steel

Cov txheej txheem tsim khoom ntawm austenitic stainless hlau yog qhov zoo, tshwj xeeb tshaj yog rau chromium-nickel austenitic stainless hlau. Ntau yam kev siv tshwj xeeb ntawm phaj, raj, sawb, xaim, bar Tshuag, thiab forgings thiab castings tuaj yeem ua tau zoo siv cov txheej txheem los ua cov hlau tshwj xeeb.

Vim muaj cov ntsiab lus siab ntawm cov ntsiab lus hlau (tshwj xeeb tshaj yog chromium) thiab cov ntsiab lus tsis tshua muaj carbon, feem ntau austenitic stainless hlau yog tsim nyob rau hauv ntau qhov siv arc rauv ntxiv rau argon-oxygen decarburization (AOD) los yog nqus pa decarburization (VOD) txoj kev. Rau cov khoom lag luam qib siab me me, lub tshuab nqus tsev lossis lub tshuab nqus tsev tsis siv lub tshuab nqus tsev tuaj yeem siv tau, thiab hluav taws xob slag remelting yuav tsim nyog yog tias tsim nyog.

Qhov zoo tshaj plaws thermoplastic khoom ntawm chromium-nickel austenitic stainless hlau ua kom yooj yim ua haujlwm kub xws li forging, dov, kub tho, thiab extrusion. Cov cua kub ntawm cov hlau ingot yog 1150-1260 ℃, thiab deformation kub ntau yog feem ntau 900-1150 ℃. Cov qib hlau uas muaj tooj liab, nitrogen, thiab ruaj khov nrog titanium thiab niobium zoo li tso siab rau qhov kub thiab txias, thaum cov qib chromium thiab molybdenum steel siab yuav cia siab rau qhov kub thiab txias. Vim tsis zoo thermal conductivity, lub sij hawm rwb thaiv tsev yuav tsum ntev dua.

Tom qab ua haujlwm kub, lub workpiece tuaj yeem ua cua txias. Chromium manganese austenitic stainless hlau muaj lub zog rhiab heev rau kub tawg. Thaum lub steel ingot qhib, me me deformation thiab ntau dhau yuav tsum tau, thiab forgings yuav tsum tau stacked thiab txias. Nws tuaj yeem ua cov txheej txheem txias txias xws li txias dov, kos duab txias, thiab spinning, nrog rau kev ua haujlwm xws li stamping, dabtsi yog khoov, curling, thiab folding.

Kev ua haujlwm hnyav ntawm chromium-nickel austenitic stainless hlau tsis muaj zog dua li ntawm chromium-manganese hlau, thiab qhov txias deformation tom qab ib qho annealing tuaj yeem ncav cuag 70% mus rau 90%. Txawm li cas los xij, vim tias qhov siab deformation tsis kam thiab muaj zog ua haujlwm hardening nyiam ntawm chromium manganese austenitic stainless hlau, tus naj npawb ntawm nruab nrab softening annealing yuav tsum tau nce. Kev kho mob nruab nrab nruab nrab softening annealing yog dej txias ntawm 1050-1100 ℃.

Austenitic stainless hlau kuj tseem siv tau los tsim cov castings. Txhawm rau txhim kho cov kua dej ntawm cov hlau thiab txhim kho qhov kev ua tau zoo, cov hlau alloy muaj pes tsawg leeg ntawm cov hlau casting yuav tsum tau hloov kho: ua kom cov ntsiab lus silicon, nthuav dav cov ntsiab lus ntawm chromium thiab npib tsib xee, thiab ua rau cov kev txwv sab sauv ntawm cov ntsiab lus ntawm cov ntsiab lus sulfur. .

Austenitic stainless hlau yuav tsum raug rau kev kho mob ua ntej siv los ua kom cov khoom siv ntawm carbides thiab lwm yam precipitates nyob rau hauv cov hlau mus rau hauv lub austenite matrix, thaum tseem homogenizing tus qauv thiab tshem tawm kev ntxhov siab, yog li kom ntseeg tau zoo heev corrosion kuj thiab txhua yam khoom. Txoj kev kho kom raug yog kom sov ntawm 1050-1150 ℃ thiab tom qab ntawd dej txias (qhov nyias nyias tuaj yeem ua cua txias). Kev kho qhov kub thiab txias yog nyob ntawm qib alloying ntawm cov hlau: qis-molybdenum lossis qis-molybdenum steel qib yuav tsum qis dua (≤1100 ℃), thaum cov qib alloyed siab dua xws li 00Cr20Ni18Mo-6CuN, 00Cr25Ni22Mo2N, thiab lwm yam yuav tsum siab dua (1080 -1150 ℃).

Advanced technologies yog dav siv nyob rau hauv ntau lawm, xws li refining tus nqi sab nraum lub cub tawg mus txog 95%, qhov nruam casting piv tshaj 80%, thiab cov high-speed dov mills, precision, thiab ceev forging tshuab tau lug txhawb nqa. Hauv particular, kev siv hluav taws xob hauv computer tswj hauv smelting thiab ua kom muaj kev ntseeg siab thiab ruaj khov ntawm cov khoom zoo thiab kev ua haujlwm.
