Vuam ntawm austenitic stainless hlau yeeb nkab

Abstract: Qhov kev sib tw no tsuas yog kawm txog kev siv vuam kev siv tshuab thiab thev naus laus zis ntawm austenitic stainless hlau yeeb nkab taub qab sib koom ua ke. Lub vuam ntawm 0Cr18Ni9 austenitic stainless hlau nrog tungsten arc vuam (TIG) muaj cov tshuab tshwj xeeb thiab kev ua haujlwm, thiab nws tau dav siv hauv kev lag luam machining. Cov. Vim hais tias r18Ni9 austenitic stainless hlau tau raug welded, lub weld thiab tshav kub cuam tshuam cheeb tsam

(HAZ) Qhov tawg yog rhiab heev thiab lub pob welded yog qhov cuam tshuam rau intergranular xeb. Txhawm rau daws qhov teeb meem no, txoj kev no siv cov kev tiv thaiv kev tiv thaiv kev ua haujlwm nyob rau hauv cov hlau thiab cov txheej txheem ua xim hlau. Tom qab vuam, cov vuam sib txuas ntawm txoj hlua txuas tuaj yeem kov tsis dhau tom qab soj ntsuam vuam, thiab tuaj yeem ua tau raws li qhov xav tau tam sim no. Cov ntsiab lus: ntxhiab tsw stainless californium: txheej txheem vuam; tshav kub-cuam tshuam cheeb tsam; Crystal Indirect corrosion

Nyob rau lub xyoo pua 21st, nrog rau txoj kev loj hlob sai ntawm kuv lub teb chaws' s tshuab kev lag luam thiab kev tsim khoom, kev lag luam kev lag luam ntawm stainless hlau tau nce ceev ceev. Nyob rau xyoo 2001, kev noj tau ntau dhau 2.2 lab tons thiab nce txog 5.22 lab tons hauv 2005. Tom qab ntawd, kev noj haus tau nce ntau nyob rau txhua xyoo. Txog rau xyoo 2017, Tuam Tshoj' s stainless hlau crude steel tso zis yog 25.7915 lab tons, uas tau dhau los ua lub ntiaj teb' s feem ntau austenitic stainless hlau. Nws muaj qhov ua tau zoo weldability, toughness, corrosion tsis kam, thiab kev siv tshuab ua tau zoo, yog li nws nyob rau hauv txoj haujlwm tseem ceeb hauv kev siv tshuab kev lag luam hauv Suav teb thiab thoob ntiaj teb, thiab siv dav hauv cov tsheb qhuav tsim, siab ntim cia tank, siv choj, aerospace, nkoj thiab rooj tog zaum kho kom zoo nkauj kev lag luam. Hauv kev tsim thiab kev tsim tawm ntawm stainless hlau workpieces, vuam yog yam ua tsis tseem ceeb ntawm kev siv lub tshuab. Raws li daim ntawv thov ntawm stainless hlau ua ntau dua thiab ntau dua, qhov yuav tsum tau ua rau cov neeg kho tshuab zog thiab kev ua tau zoo ntawm cov khoom sib txuas qhov txuas tau hloov tas li, yog li cov tseev kom muaj rau cov hau kev cov txheej txheem thiab cov txheej txheem muaj ntau zuj zus ntxiv. Ntxiv mus, nrog kev qhia paub txuas ntxiv ntawm cov tshiab thev naus laus zis hauv lwm lub teb chaws nrog kev tsim kev lag luam, qee cov ntaub ntawv txawv teb chaws tshiab, cov cuab yeej tshiab vuam lossis vuam cov txheej txheem txuas ntxiv cuam tshuam rau kev lag luam stainless hlau hauv tsev. Yog li ntawd, cov kev xav tau siab dua tau muab tso rau cov kev lag luam stainless hlau machining tshuab, tshwj xeeb tshaj yog Piv nrog cov vuam tshuab ntawm txawv teb chaws, tshwj xeeb tshaj yog nyob rau qee lub teb chaws tsim khoom, kuv lub teb chaws tseem muaj qhov sib txawv loj, feem ntau hauv cov khoom siv vuam, vuam cov khoom siv, vuam kev thiab cov txheej txheem Cov. Ib qho ntxiv, qee tus qauv vuam siv nyob hauv kuv lub teb chaws yog Tus Txheeb Ze. Yog li ntawd, nrog txoj kev loj hlob sai ntawm kev tsim khoom hauv kuv lub teb chaws, qhov zoo ntawm austenitic stainless hlau vuam txoj kev thiab cov txheej txheem, cov khoom siv vuam thiab vuam khoom yuav tsum tau txuas ntxiv txhim kho kom ntseeg tau cov khoom siv vuam vuam zoo thiab maj mam txo cov kis nrog txawv teb chaws. Nyob rau tib lub sijhawm, nws yog qhov yuav tsum tau ntxiv dag zog rau kev tshawb fawb thiab kev txhim kho ntawm qhov tshwj xeeb zoo stainless hlau vuam siv tau thiab vuam siv tshuab kom tau raws li qhov xav tau ntawm niaj hnub no' s nyob hauv tsev thiab txawv teb chaws stainless hlau tau txais kev lag luam, txhim kho kuv lub teb chaws' s tus kheej kev sib tw, thiab pab txhawb kuv lub teb chaws' s kev tsim khoom.
