Yam khoom

Stainless hlau nrog lub cev-centered cubic lattice ferrite ua lub hauv paus nrog cov ntsiab lus chromium ntawm 12 feem pua ​​​​rau 30 feem pua ​​​​ntawm qhov kub thiab txias. Cov hlau no feem ntau tsis muaj npib tsib xee, thiab qee qhov muaj cov khoom me me xws li molybdenum, titanium lossis niobium. Nws muaj qhov zoo oxidation tsis kam, corrosion kuj thiab kuj chloride corrosion cracking. Ferritic stainless hlau tuaj yeem muab faib ua low-chromium, nruab nrab-chromium thiab high-chromium raws li cov ntsiab lus chromium. Raws li cov purity ntawm cov hlau, tshwj xeeb tshaj yog cov carbon thiab nitrogen impurity cov ntsiab lus, nws yuav muab faib ua ferritic stainless hlau zoo tib yam thiab ultra-ntshiab ferritic stainless hlau. Ordinary ferritic stainless hlau muaj qee qhov tsis zoo xws li qhov kub thiab txias hauv chav tsev kub brittleness, notch rhiab heev, siab nyiam rau intergranular corrosion thiab tsis zoo weldability. Txawm hais tias hom hlau no tau tsim ua ntej, nws daim ntawv thov kev lag luam tau txwv ntau heev. Cov kev tsis txaus ntawm cov hlau tsis zoo li qub ferritic stainless hlau muaj feem xyuam rau cov purity ntawm cov hlau, tshwj xeeb tshaj yog cov ntsiab lus siab ntawm interstitial ntsiab xws li carbon thiab nitrogen hauv cov hlau. Ntev npaum li cov pa roj carbon thiab nitrogen hauv cov hlau tsis txaus, xws li tsis pub ntau tshaj 150 × 10 ~ 250 × 10, cov kev tsis txaus siab saum toj no tuaj yeem kov yeej. Txij li thaum xyoo 1970, vim yog kev tsim cov tshuab smelting, tshwj xeeb tshaj yog lub tshuab nqus tsev metallurgy thiab theem nrab refining thev naus laus zis, high-purity ferritic stainless hlau nrog carbon ntxiv nitrogen Tsawg dua los yog sib npaug li 150 ~ 250 × 10 tau tsim, ua rau hom hlau no dav. siv hauv kev lag luam.

Feem ntau nws tuaj yeem muab faib ua ferritic stainless hlau zoo tib yam thiab high-purity ferritic stainless hlau.

Feem ntau ferritic stainless hlau muaj xws li qis, nruab nrab thiab siab chromium cov ntsiab lus. Tsawg chromium ferritic stainless hlau muaj li ntawm 11 feem pua ​​​​rau 14 feem pua ​​​​chromium, xws li 00cr12 thiab 0cr13al hauv kuv lub tebchaws. American AISI400, 405, 406MF-2. Cov hlau no muaj zoo toughness, plasticity, txias deformability thiab weldability. Vim tias cov hlau muaj qee yam ntawm chromium thiab txhuas, nws muaj oxidation zoo thiab xeb kuj. 05 tuaj yeem siv ua cov roj refining ntauwd, cia tank hauv ob sab phlu, chav turbine hniav, kub siab sulfur corrosion kuj ntaus ntawv, thiab lwm yam. 400 yog siv los ua cov khoom siv hauv tsev thiab chaw ua haujlwm, thiab lwm yam. cov kav dej, thiab lwm yam. Nruab nrab chromium ferritic stainless hlau nrog chromium cov ntsiab lus ntawm 14 feem pua ​​​​rau 19 feem pua, xws li hauv tsev 1Cr17, 1Cr17Mo. US AISI 429, 430, 433, 434, 435, 436, 439. Cov hlau no muaj xeb zoo thiab corrosion kuj. Nws txoj hauj lwm hardening coefficient yog me me (n≈2), thiab nws qhov sib sib zog nqus nqus kev ua tau zoo, tab sis nws cov ductility tsis zoo.

High-purity ferritic stainless hlau muaj cov pa roj carbon tsawg heev thiab nitrogen; siab chromium, molybdenum, titanium, niobium thiab lwm yam khoom. Xws li domestic 00Cr17Mo, 00Cr18Mo2, 00Cr26Mol, 00Cr30Mo2 thiab txawv teb chaws 18-2, Cr26Mol, 25Cr-5Ni{{15 }}Mo-Nb, MoNiT, Al29-4, Al{18}}. Cov hlau no muaj cov khoom siv zoo (tshwj xeeb tshaj yog toughness), weldability, tsis kam mus rau intergranular corrosion, pitting thiab crevice corrosion, thiab zoo heev tiv thaiv kev nyuaj siab corrosion cracking. Piv txwv li, 18-2 muaj corrosion kuj zoo nyob rau hauv nitric acid, acetic acid thiab NaOH, pitting corrosion kuj nyob rau hauv 3 feem pua ​​NaCl thiab FeCl3 yog sib npaug los yog siab tshaj 18-8 austenitic steel, thiab SCC kuj yog ntau dua. tshaj 18 -8 Hlau. 26CrMo steel yog resistant rau corrosion nyob rau hauv ntau yam xov xwm, tshwj xeeb tshaj yog nyob rau hauv cov organic acids, oxidizing acids thiab muaj zog alkalis. Zoo pitting kuj nyob rau hauv muaj zog chloride media.

Daim ntawv thov

Thawj daim ntawv thov yog nyob rau hauv lub tso pa system ntawm lub tsheb cav. Nyob rau hauv kaum xyoo dhau los, nb-muaj ferritic stainless hlau siv nyob rau hauv cov teb chaws Europe thiab lub tebchaws United States tau loj hlob sai heev, tshwj xeeb tshaj yog rau lub tsheb tso tsheb. Qhov no yog vim tias kev tsim kho thev naus laus zis ntawm kev lag luam tsheb tau ntsib kev txo nqi, kev nyab xeeb thiab kev tiv thaiv ib puag ncig. Txij li thaum tau txais yuav tsum tau ntsuas rau kev tswj lub tsheb tso tawm hauv xyoo 1970, kev siv cov hlau tsis muaj steel tau nce siab heev. Txhua lub tsheb siv li ntawm 23-25kg stainless hlau. Raws li kev suav ntawm kev muag khoom txhua xyoo ntawm 15.02 lab lub tsheb thaum lub sijhawm ntawd, nws yuav tsum siv ntau dua 40,000 tons. Stainless hlau.

Secondly, nws yog siv rau supercritical kub ferritic tshav kub-resistant stainless hlau rau lub hwj chim noj. Cov boilers siv rau lub zog tsim nyob rau hauv lub ntiaj teb no tab tom txhim kho mus rau qhov kub thiab txias siab thiab muaj peev xwm loj ntawm chav, uas yuav tsum tau zoo dua kub siab zog boiler steel. Txhim kho tag nrho cov khoom.

Kuj tseem muaj cov hlau tsis muaj steel uas tiv taus atmospheric corrosion hauv architectural kho kom zoo nkauj. Stainless hlau forging yog tus cwj pwm los ntawm nws cov qauv kev puas tsuaj thiab tuaj yeem tiv taus qhov kub siab tshaj 700 degree. Yog li ntawd, cov roj muaj qhov kub thiab txias tiv taus thiab atmospheric corrosion kuj. Cov txiaj ntsig zoo no ua rau daim ntawv thov ntawm cov hlau tsis muaj steel hauv kev tsim kho sai. Piv txwv li, qee qhov chaw ua yeeb yam, cov tsev hauv tshav dav hlau hauv Nyij Pooj thiab lub ru tsev ntawm lub chaw ntau pob loj rau 2002 World Cup football match yog ua los ntawm ferritic stainless hlau.

Thaum kawg, muaj stainless hlau rau cov khoom siv hauv tsev. Stainless hlau yog dav siv hauv cov khoom siv hauv tsev, maj mam hloov cov yas thiab cov pa roj carbon steel.
