Qhov Zoo ntawm Microstructure Piav Qhia
Lub zog tiag tiag ntawm2205 Duplex Stainless Hlau Hlau Hluanyob hauv nws cov qauv me me. Cia peb tshawb nrhiav seb lub kaw lus dual-phase no ua rau kev ua tau zoo li cas:
1. Qhov Sib Piv Zoo Tshaj Plaws Rau Qhov Hnyav
Cov theem ferritic muab cov txiaj ntsig zoo thiab lub zog tensile, thaum cov theem austenitic ua kom muaj ductility thiab toughness. Qhov kev sib xyaw ua ke no muab 2205 Duplex ze li ntawmob npaug ntawm lub zog tawm losntawm 304 lossis 316 stainless hlau, tso cai rau cov neeg tsim qauv siv cov hlua me dua yam tsis muaj kev cuam tshuam rau lub peev xwm thauj khoom.
2. Kev Tiv Thaiv Kev Sib Tsoo Zoo Dua
Cov qauv me me tiv thaiv kev xeb hauv zos, tshwj xeeb tshaj yogkev khawb avthiabkev xeb ntawm qhov tawg, uas feem ntau tshwm sim hauv cov chaw muaj chloride ntau xws li dej hiav txwv lossis cov chaw tsim tshuaj lom neeg. Qhov muaj chromium (22%) thiab molybdenum (3%) sib npaug pab tswj kom muaj zaj duab xis tiv thaiv ntawm qhov chaw, txawm tias nyob rau hauv cov xwm txheej acidic lossis saline.
3. Kev Tiv Thaiv Kev Nyuaj Siab Corrosion Cracking (SCC)
Ib qho ntawm cov teeb meem loj tshaj plaws rau cov hlau tsis xeb hauv cov chaw ua dej hiav txwv thiab cov chaw ua roj yog chloride-induced SCC. Ua tsaug rau nws cov theem ferrite, 2205 Duplex exhibitskev tiv thaiv zoo heevrau hom kev ua tsis tiav no, ua kom muaj kev ruaj khov mus sij hawm ntev hauv ob qho kev siv nro thiab torsion.
4. Kev Tiv Thaiv Kev Qaug Zog
Hauv cov chaw muaj zog, xws li cov tshuab nqa neeg, cov cranes, lossis cov tshuab nqa khoom hauv hiav txwv, cov hlua hlau raug rau kev khoov thiab thauj khoom ntau zaus. Lub microstructure duplex muab kev tiv thaiv kev qaug zog zoo heev, ua rau nws ruaj khov dua nyob rau hauv kev ntxhov siab cyclic dua li cov hlau stainless ib theem.
5. Kev Txhim Kho Weldability thiab Kev Ruaj Ntseg ntawm Cov Qauv
Txawm hais tias kev vuam yuav hloov pauv qhov sib npaug ntawm ntau cov hlau sib xyaw, 2205 Duplex tswj tau qhov ruaj khov microstructure thaum ua tiav kom raug. Nws lub peev xwm los tiv thaiv kev sib cais theem thaum vuam ua kom muaj kev ua tau zoo thiab lub zog thoob plaws tag nrho cov qauv hlua.
Yuav ua li cas Microstructure cuam tshuam rau kev ua haujlwm ntawm cov hlua hlau
Kev sib xyaw ua ke ntawm ferrite thiab austenite theem muab cov2205 Duplex Stainless Hlau Hlau Hluakev sib koom tes tshwj xeeb uas txhais tau tias muaj txiaj ntsig zoo hauv kev ua tau zoo hauv lub ntiaj teb tiag.
