Austenitic stainless hlau hais txog stainless hlau nrog cov qauv austenitic ntawm chav tsev kub. Austenitic stainless hlau yog ib qho ntawm tsib chav kawm ntawm stainless hlau los ntawm crystalline qauv (nrog rau ferritic, martensitic, duplex thiab nag lossis daus hardened). Thaum cov hlau muaj txog 18% Cr, 8% -25% Ni, thiab txog 0.1% C, nws muaj cov qauv austenite ruaj khov. Austenitic chromium-nickel stainless hlau suav nrog lub npe nrov 18Cr-8Ni steel thiab siab Cr-Ni series steel tsim los ntawm kev ntxiv Cr thiab Ni cov ntsiab lus thiab ntxiv Mo, Cu, Si, Nb, Ti thiab lwm yam ntawm lub hauv paus no. Austenitic stainless hlau yog tsis-sib nqus thiab muaj siab toughness thiab yas, tab sis nws lub zog yog tsawg, thiab nws yog tsis yooj yim sua kom ntxiv dag zog rau nws los ntawm theem transformation. Nws tsuas tuaj yeem ntxiv dag zog los ntawm kev ua haujlwm txias. Yog hais tias cov khoom xws li S, Ca, Se, Te ntxiv, nws muaj cov khoom zoo ntawm machinability.

Auto Parts Casting los ntawm Kev nqis peev Casting ntawm Autenitic Stainless hlau
Austenitic stainless hlau kuj tuaj yeem tsim castings, feem ntau yog los ntawmpeev casting txheej txheem. Txhawm rau txhim kho cov dej ntws ntawm cov hlau molten thiab txhim kho kev ua tau zoo, cov alloy muaj pes tsawg leeg ntawm cov cam khwb cia hlau yuav tsum tau hloov kho los ntawm kev ua kom cov ntsiab lus silicon, ua kom muaj ntau yam ntawm chromium thiab npib tsib xee cov ntsiab lus, thiab ua rau lub siab txwv ntawm impurity element sulfur.
Austenitic stainless hlau yuav tsum yog cov khoom siv-kev daws teeb meem ua ntej siv, txhawm rau ua kom cov khoom siv ntau tshaj plaws ntawm ntau yam precipitates xws li carbides hauv cov hlau rau hauv austenite matrix, thaum tseem ua kom homogenizing cov qauv thiab tshem tawm kev ntxhov siab, thiaj li ua kom zoo corrosion kuj thiab mechanical zog. Txoj kev kho kom raug yog dej txias tom qab cua sov ntawm 1050 ~ 1150 ℃ (qhov nyias nyias tuaj yeem ua cua txias). Kev kho qhov kub thiab txias yog nyob ntawm qib ntawm alloying ntawm cov hlau: Molybdenum-dawb lossis qis-molybdenum steel qib yuav tsum qis dua (≤1100 ℃), thiab siab dua alloyed qib xws li 00Cr20Ni18Mo-6CuN, 00Cr25Ni22Mo2N, thiab lwm yam yuav tsum siab dua ( 1080 ~ 1150 ℃).
Austenitic 304 stainless hlau hlau phaj, uas tau hais tias coj muaj zog tiv thaiv xeb thiab corrosion kuj, thiab muaj cov yas zoo heev thiab tawv, uas yooj yim rau stamping thiab sib sau. Nrog ib tug ceev ntawm 7.93g / cm3, 304 stainless hlau yog ib tug ntau heev stainless hlau, kuj hu ua 18/8 stainless hlau nyob rau hauv kev lag luam. Nws cov khoom siv hlau tiv taus qhov kub thiab txias thiab muaj kev ua haujlwm zoo, yog li lawv tau siv dav hauv kev lag luam thiab rooj tog kho kom zoo nkauj industries thiab khoom noj khoom haus thiab kev kho mob kev lag luam.
