Txheej txheem cej luam ntawm Stabilization Thaum tshav kub kub kho rau SS 347:
1. Tshuaj Annealing:
Thawj kauj ruam hauv kev kho cua sov stabilization yog kev daws annealing. Qhov no suav nrog cua sov AISI 347 stainless hlau Cov khoom siv rau qhov kub thiab txias feem ntau nyob rau hauv thaj tsam ntawm 1900 ° F txog 2050 ° F (1038 ° txog 1121 ° F). Cov1.4550 khoom steelTom qab ntawd tuav ntawm qhov kub siab no rau ib lub sijhawm tshwj xeeb, tso cai rau cov chromium carbides yaj rov qab rau hauv matrix ntawm stainless hlau.
2. Ceev Quenching:
Tom qab lubhom 347 stainless hlau khoomtau tuav ntawm cov tshuaj annealing kub rau lub sij hawm yuav tsum tau, nws yog ceev quenched. Kev nrawm nrawm pab kaw cov pa roj carbon thiab nitrogen rov qab rau hauv cov khoom siv hauv cov hlau tsis huv, tiv thaiv kev hloov pauv ntawm chromium carbides ntawm cov ciam teb.
3. Stabilization Annealing:
Tom qab cov tshuaj annealing thiab quenching, 347 ss cov khoom siv yog raug rau cov txheej txheem stabilization annealing. Cov kauj ruam no yog qhov tseem ceeb rau SS 347 vim nws cov ntsiab lus niobium (columbium). CovS34700 khoomyog rhuab mus rau qhov kub thiab txias feem ntau nyob rau hauv thaj tsam ntawm 1550℃F mus rau 1650℃F (843℃rau 899 degree) thiab ces cia kom txias maj mam. Qhov no stabilizes cov khoom los ntawm kev txhawb cov nag lossis daus ntawm niobium carbides es tsis txhob chromium carbides ntawm cov qoob loo.
4. Cua txias:
Lub stabilizedSA 347 stainless hlau khoomtso cai kom txias maj mam. Kev ua kom txias qeeb yuav pab ua kom tiav qhov xav tau microstructure thiab xyuas kom muaj cov niobium carbides, uas txhim kho corrosion kuj ntawm cov1.4550 stainless hlau.
SS 347 yog austenitic stainless hlau uas muaj niobium (Nb) los muab kev tiv thaiv corrosion zoo heev. Lub stabilization kev kho cua sov ntawm stainless hlau 347 muaj ib tug txheej txheem hu ua kua annealing los yog stabilization annealing. Nws yog ib qho tseem ceeb los pab tswj kev tiv thaiv corrosion ntawm 347 cov khoom, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig raug kub. Peb cov neeg muag khoom tuaj yeem muab tau347 stainless hlau yeeb nkabs, phaj, fittings, flanges, thiab lwm yam. Hu rau peb kom paub ntau ntxiv thiab ib qho kev tsocai pub dawb.
Cov txiaj ntsig ntawm Stabilization Thaum tshav kub kub kho nrog SS 347
1. Muaj Kev Tiv Thaiv Corrosion:Los ntawm kev tiv thaiv kev tsim ntawm chromium carbides, qhov kev pheej hmoo ntawm intergranular corrosion yog txo qis. Qhov no, nyob rau hauv lem, nce lub zuag qhia tag nrho corrosion kuj ntawm cov khoom.
2. Txhim kho Weldability:Vuam tuaj yeem ua rau rhiab heev hauv austenitic stainless hlau, ua rau intergranular corrosion. Stabilization kev kho cua sov minimizes cov nyhuv no, uaSIB 347yooj yim rau weld.
3. Txhim kho Durability:Los ntawm kev txo cov kev pheej hmoo ntawm corrosion, SS 347 yuav ua tau ntev dua, nrog rau lub neej ntev thiab txo nqi txij nkawm.
