Dab tsi yog cov khoom siv 1.4301 stainless hlau?
1.4301 yog ntau yam austenitic stainless hlau, hu ua "classic V2A," muaj nuj nqis heev rau nws cov corrosion kuj zoo heev, zoo formability (sib sib zog nqus nqus), thiab weldability. Nws 18/8 chromium-nickel muaj pes tsawg leeg tso cai rau kev tsim tus kheej- kho cov txheej txheem oxide, ua rau nws siv dav hauv cov ntawv thov xws li cov khoom siv hauv chav ua noj, kho kom zoo nkauj vaj tsev, thiab cov khoom ua zaub mov.
Cov khoom siv dab tsi yog 1.4301 sib npaug rau stainless hlau?
Khoom siv 1.4301 yog European tus qauv (EN) tsim rau dav siv AISI 304 stainless hlau, los yog X5CrNi18-10. Nws yog austenitic stainless hlau uas muaj 18% chromium thiab 8% npib tsib xee, thiab yog hom stainless hlau feem ntau, qee zaum hu ua "18/8". Nws yog sib npaug rau UNS S30400, JIS SUS 304, thiab BS 304S31.
Puas yog EN 1.4301 Ib yam li AISI 304 Stainless Hlau?
Yog lawm, EN 1.4301 thiab AISI 304 stainless hlau yog qhov tseem ceeb tib yam; lawv tsuas yog siv cov qauv naming sib txawv tab sis xa mus rau tib qib siv austenitic stainless hlau. Vim nws 18% chromium thiab 8% nickel cov ntsiab lus, nws feem ntau hu ua "18/8 stainless hlau." Muaj qhov sib txawv me ntsis hauv lawv cov tshuaj muaj pes tsawg leeg, piv txwv li, 1.4301 muaj cov ntsiab lus ntawm sulfur me ntsis.

1.4301 Corrosion Resistance
1.4301 stainless hlau nthuav tawm zoo heev corrosion kuj nyob rau hauv ntau qhov chaw thiab thaum nyob rau hauv kev sib cuag nrog txawv corrosive xov xwm. Pitting thiab crevice corrosion yuav tshwm sim nyob rau hauv ib puag ncig uas muaj chlorides. Kev ntxhov siab corrosion tawg tuaj yeem tshwm sim ntawm qhov kub siab tshaj 60 degree.
1.4301 Kub Resistance
1.4301 stainless hlau tuaj yeem tiv taus oxidation mus txog 870℃raws li kev siv tsis sib xws; thiab mus txog 925℃raws li kev siv tas mus li. Txawm li cas los xij, kev siv tsis tu ncua hauv qhov kub ntawm 425-860℃tsis pom zoo. Hauv qhov no, 1.4307 stainless hlau raug pom zoo.
1.4301 Stainless hlau cua sov kho
304 stainless hlau tsis tuaj yeem hardened los ntawm kev kho cua sov. Kev kho los yog annealing tuaj yeem ua tau los ntawm cua sov ntawm qhov kub ntawm 1010-1120℃tom qab txias txias.
Qhov sib txawv ntawm 1.4301 thiab 1.4305 stainless hlau:
Ob leeg 1.4301 (AISI 304) thiab 1.4305 (AISI 303) yog austenitic stainless hlau uas muaj cov ntsiab lus zoo sib xws, tab sis 1.4305 tau ntxiv sulfur los txhim kho nws cov machinability, ua kom yooj yim txiav thiab zoo li 1.4301.
