Dab tsi yog sus321 stainless hlau?
Sus321 stainless hlau yog ni - b - ti ustenitic stainless hlau ruaj khov nrog titanium. Nws muaj cov tshuaj tiv thaiv corrosion zoo heev, siab- kub lub zog, thiab creep tsis kam. It is suitable for high-temperature welded components, such as boiler heat exchangers and chemical equipment, providing corrosion protection in elevated-temperature environments and ensuring long-term stable operation. Sus321 Ua haujlwm ua qhov kev xaiv tau zoo rau kev siv cov ntawv thov engineering nyob rau hauv high- tej kev mob kub.
Vim li cas thiaj xaivSus321 Stainless HlauRau tshav kub -} Cov ntawv thov tiv taus?
1.titanium stabilization tiv thaiv
Chromium carbide yuav daus ntawm 425-850 degree, ua rau muaj kev tsis txaus ntseeg ntawm 304/316 stainless hlau. Sus321 tau zoo rau suppresses intergranular corrosion los ntawm kev tsim titanium carbide (TIC) cov qauv. Nws tswj hwm tau zoo nyob nruab nrab corrosion tsis kam nyob rau hauv 427-816℃ntau, whereas 316L stainless hlau yog ib txwm muaj kev paub txog thaum muaj kub.
2.Txhua qib siab - lub zog kub
Rau kev pabcuam txuas ntxiv, sus321 tuaj yeem tiv taus kub txog900 degree(Cov kev pabcuam sib txawv txog li 925 Degree) tsis muaj scring lossis embrittlement. Txawm nyob600 degree, nws khaws cov kev ua haujlwm zoo ib yam, nrog lub zog tensile kwv yees li520-700 MPathiab paib lub zog nyob ib puag ncig205-310 MPa.
3. Dindustry cov ntawv thov
Petrochemical Kev Lag Luam:Qum tawg rauv leeg, flare stacks (leej faj - resistant).
Aerospace kev lag luam:Dav hlau cav Cheebtsam, tom qab cov hnab loj dua.
Lub hwj huam nroj tsuag:Cov leeg Boiles Boiler, Cheebtsam Super.

Ua thiab Txij Nkawm
Kev Kho Cua Sov:Sus321 yuav tsum muaj kev daws anchaling ntawm920-1150 degreethiab kev kho mob ruaj khov ntawm850-930 QIBTxhawm rau kom ntseeg tau tias carbide spare thiab ntxiv txhim kho thaum tshav kub kub ntxiv.
Vuam txheej txheem
Vuam yuav tsum tau tswj txoj kev tam sim no (120–150 A) thiab vuam ceev (15-20 cm / min). Titanium Ruaj Khetilization tuaj yeem tiv thaiv nag los nag lossis daus hauv weld los ntawm kwv yees li75%, txhim kho corrosion tsis kam.
Tuaj yeem sus321 tiv taus thermal cycling?
Yog lawm, Sus321 tswj xyuas kev ncaj ncees thiab tiv taus scaling txawm tias nyob rau hauv cov cua sov uas pheej yig thiab txias.
Rau tej cua sov -} illsant thov, sus321 stainless hlau muaj cov kev ua tau zoo dua li sus304. Nws cov titanium stabilization, siab- kub lub zog, thiab oxidation lub zog ua rau nws muaj qhov ruaj khov, ntev}} kav cov ntaub ntawv.
