Hauv tsab xov xwm no, peb yuav txwv peb qhov kev sib tham rau austenitic stainless hlau, txawm hais tias ntau cov lus siv rau lwm hom thiab.Ntau yam khoom muaj teeb meem tsis muaj kev tswj hwm thiab yuav tsum tau teev tseg ntawm tus neeg siv khoom tshwj xeeb lossis kev yuav khoom.Tsis txhob xav tias cov alloy koj tab tom yuav yog tsim los ntawm qhov nruab nrab ntawm txhua yam khoom.Txij li thaum xyoo 1988, steel mills tau muaj ib qho kev pab cuam hu ua "alloy chipping" uas siv qhov tsawg kawg nkaus ntawm alloying ntsiab xwb los tiv thaiv kub embrittlement thiab txias dov tawg.
Qib Tsim Austenitic stainless hlau yog tsim los muab kev tiv thaiv corrosion hauv ntau qhov chaw, tiv thaiv hydrogen thiab embrittlement ntawm 885ºF (475ºC), lub zog zoo, zoo ductility thiab tsis tshua muaj zog.Stainless hlau hauv nws daim ntawv yooj yim tshaj plaws yog hlau nrog tsawg kawg 12% chromium.Qhov no yog dab tsi ua rau stainless hlau resistant rau xeb thiab tso cai rau ib tug passive zaj duab xis rau tsim.Stainless hlau muaj nyob rau hauv peb lub xeev metallurgical nyob ntawm seb muaj pes tsawg leeg thiab kev kho cua sov: ferritic, martensitic thiab austenitic.Cov npe no hais txog cov qauv siv lead ua: ferrite yog lub cev-centered cubic, austenite yog lub ntsej muag-centered cubic, thiab martensite yog ib tug twisted tetragonal system, uas yog, ib tug twisted lub ntsej muag-centered cubic qauv ua lub cev-centered.
Cov hlau ntshiab muaj lub cev-centered cubic duab thiab tshwm sim los ntawm xoom xoom mus rau nws qhov melting point.Thaum qee cov ntsiab lus ntxiv, "gamma rings" lossis austenite raug tsim.Cov ntsiab lus no yog carbon, chromium, npib tsib xee, manganese, tungsten, molybdenum, silicon, vanadium thiab silicon.Ntawm cov ntsiab lus no, npib tsib xee, manganese, chromium thiab carbon muaj peev xwm nthuav tau lub nplhaib gamma qhov deb tshaj plaws.Nws yog kev sib xyaw ntawm npib tsib xee thiab chromium uas ua rau austenitic stainless steels ntsej muag nyob rau hauv nruab nrab cubic ntawm kiag li xoom mus rau lub melting point.Nws yog lub nplhaib gamma uas txawv ferritic alloys los ntawm martensitic sawv daws yuav.Cov ntsiab lus chromium ntawm martensitic stainless hlau yog nqaim heev, 14-18%, thiab yuav tsum muaj cov pa roj carbon monoxide, vim hais tias tsuas yog thaum rhuab hauv qhov ntau no tuaj yeem tsim cov austenite ntshiab, kom martensite tuaj yeem tau los ntawm quenching.Ferritic alloys muaj cov ntsiab lus qis dua 14% lossis siab dua 18%.Hloov cov ntsiab lus alloying tuaj yeem hloov qhov ntau.Txoj kev tshaj plaws yog ua kom koj cov carbs qis.
Feem ntau cov austenitic stainless hlau raws li muaj pes tsawg leeg 18-8, 18% Cr 8% Ni.Yog tias cov ntsiab lus npib tsib xee hauv cov hlau ntau dua 8%, nws yog austenitic, yog tias cov ntsiab lus nickel qis dua, ces nws yog duplex steel, uas yog, austenitic nrog cov Islands tuaj ntawm ferrite.Ntawm 5% npib tsib xee, tus qauv yog kwv yees li 50% austenitic, 50% ferritic, qis dua 3% nws dhau los ua ferritic.Yog li, 8% nickel yog lub hauv paus rau qhov pheej yig tshaj austenitic stainless hlau.
Thaum cov ntsiab lus alloying ntxiv rau cov hlau, lawv tuaj yeem ua txoj haujlwm hauv lub ntsiab siv lead ua.Cov no yog hu ua hloov alloys thiab cov alloy tseem nyob ib theem.Lwm cov ntsiab lus me me kom haum ntawm cov atoms, hu ua cov ntsiab lus interstitial, thiab cov hlau tseem nyob ib theem.Lwm cov ntsiab lus yuav ua ke los tsim lawv tus kheej cov pob zeb tshwj xeeb thiab tsim cov theem tshwj xeeb.Tseem muaj lwm tus ua raws li impurities hauv cov hlau, hu ua inclusions.
