316 Ci Anealed thiab unannealed stainless hlau tubing: Dab tsi yog qhov sib txawv?
Tso lus
Dab tsi yog qhov kev ua tau zoo sib txawv ntawm SS 316 ci ntsa iab - annealed thiab unannaled seamless kav?
Kaj - Annealed 316 Stainless Hlau Seamless Yeeb Nkab Txhim Kho, ua rau nws haum siab rau qhov siab-}} chaw ib puag ncig.
Unannealed yeeb nkab, ntawm qhov tod tes, khaws nws txias - ua haujlwm nrog cov khoom siv hauv qab thiab ib txwm siv). Qhov kev xaiv yuav tsum yog raws li kev txheeb xyuas kev ua haujlwm ntawm cov kev ua haujlwm tshwj xeeb (xws li kev ua haujlwm ntawm nruab nrab, siab ua haujlwm tau).

Microstructure thiab cov qauv
Grain Lub Xeev ntawm 316 Ci analealed HlOS:Annealing ua noj recrystallization ntawm txias - ua haujlwm deformed nplej ua ke, tshem tawm cov kev ntxhib los mos thiab lattice distortion. Residual kev nyuaj siab los ntawm kev ua haujlwm txias yog qhov tseem ceeb tshem tawm (residual kev ntxhov siab tsawg dua los yog sib npaug rau deformation thaum ntev- kev siv.
Txias -} Ua haujlwm qauv ntawm Unannealed HlOS:Khaws cov txheej txheem ua tiav nrog elongated lossis distorted nplej, siab disidation kev ntxhov siab (txog 200-300mpa), muaj peev xwm ua rau muaj hnub nyoog tawg thaum lub sijhawm cia lossis siv.
Corrosion Kuj
Oxide zaj duab xis nyob ci annaled leeg:Thaum lub sijhawm Annaling, 316 Stainless hlau kav ib qho kev sib tw ua ib qho kev sib tw, ua kom siab dua cov roj av (piv txwv li siab) Yog hais tias kev daws aninging (siab {- kub txias txias) yog thov, nws tiv thaiv kev sib txawv los cuam tshuam rau kev txhim kho corrosion. Qhov no yog tshwj xeeb rau kev xeb ib puag ncig muaj chloride ions.
Nto tej yam tsis xws li hauv unannealed HlOS:Qhov saum npoo ntawm txias - Ua haujlwm 316 Stainless Hlau Kav, Oxides, uas tuaj yeem ua raws li kev pib corrosion. Residual kev txhawj xeeb yuav nrawm corrosion nkag hauv nruab nrab, ua rau nws xav ntau dua rau kev xeb hauv cov acidic lossis ntsev pov tseg ib puag ncig.
Cov Khoom Siv Zoo thiab Kev Siv
316 Nto deg ua tiav ntawm kev ci annealed Hlav:Daim iav {{0} Zoo li saum npoo (roughness ra tsawg dua los yog sib npaug los yog sib npaug, haum rau kev lag luam huv si hauv cov zaub mov thiab chaw lag luam. Conductivity thiab thermal conductivity: uniformed microstructure sib xyaw hluav taws xob / thermal conductivity, ua rau nws zoo tagnrho rau cov leeg tshav kub.
Nto tej yam tsis xws luag ntawm cov leeg unannealed:Tej zaum yuav nthuav tawm oxide discoloration, khawb, lossis pits, xav tau ntxiv pickling lossis polishing. Kev txwv kev txwv: ntxhib saum toj mus fouling, tsis tsim nyog rau high {{} {} Lub ntsej muag zoo nkauj lossis cov tshuaj, siab} kev voj voog roj thauj).
316 Ci annealed vs. unannealed tubing: kev ua tau zoo
| Qhov taw qhia kev ua tau | 316 Ci Annealed Stainless Hlau Seamless Yeeb Nkab | 316 tsis - annealed stainless hlau seamless yeeb nkab |
|---|---|---|
| Kev nyuaj | Txo Hardness (vim tias muag muag ntawm cov qauv tom qab annealing), feem ntau hv hat hardness txo los ntawm 30%- 50%. | Ntau dua hardness (raws li lattice distortion tom qab kev ua haujlwm txias tsis raug tshem tawm), HV nyuaj yog qhov siab. |
| Plasticity (elongation) | Cov plastentity muaj ho txhim kho, thiab elongation (A5) tuaj yeem ncav cuag 35% {{% (nyob ntawm cov khoom siv). | Tsawg dua cov yas, nrog elongation tsuas yog 15% - 30}}%, thiab yooj yim mus rau yooj yim tom qab ua haujlwm txias. |
| Kev muaj zog | Zoo dua cov kev cuam tshuam todlemness, tsis yog nquag mus rau brittle baciture. | Tsis muaj kev nyuaj, tshwj xeeb tshaj yog cov kev ntxhov siab tom qab cov duab kos lossis txias. |
| Luam ntawv | Pab txhawb kev ua ntxiv xws li kev khoov ntxiv, flaring, vuam, thiab lwm yam, thiab tsis yooj yim rau tawg. | Kev ua haujlwm txias tsis zoo, thiab yuam kev ua tej zaum yuav ua rau cov kab nrib pleb lossis pob txha lov. |
