Qhov sib txawv tseem ceeb ntawm 304 thiab 202 stainless hlau yog tias 304 stainless hlau muaj cov ntsiab lus siab ntawm chromium thiab npib tsib xee, uas ua rau nws tsis tshua muaj xeb, thaum 202 stainless hlau muaj tsawg ntawm chromium thiab nickel, uas ua rau nws yooj yim rau xeb.
304 stainless hlau yog ib hom stainless hlau uas muaj ob qho tib si chromium thiab npib tsib xee hlau ua cov ntsiab lus tsis yog hlau. 202 yog ib hom hlau tsis tshua muaj hlau, uas yooj yim rau xeb.
304 Stainless hlau yog dab tsi?
304 stainless hlau yog ib hom stainless hlau uas muaj ob qho tib si chromium thiab npib tsib xee hlau ua cov ntsiab lus tsis yog hlau. Nws yog feem ntau hom stainless hlau. Cov ntsiab lus ntawm chromium hauv cov hlau no nyob nruab nrab ntawm 18% txog 20%. Cov ntsiab lus ntawm nickel nyob nruab nrab ntawm 8% mus rau 10.5%. Peb tuaj yeem categorize 304 stainless hlau li austenitic stainless hlau. Feem ntau, cov hlau no tsis tshua muaj hluav taws xob thiab thermally conductive piv rau carbon steel.
304 stainless hlau yog hlau nplaum. Txawm li cas los xij, nws yog qhov sib piv tsawg dua sib nqus piv rau cov hlau. Tsis tas li ntawd, nws muaj kev tiv thaiv corrosion siab piv rau cov hlau tsis tu ncua. 304 stainless hlau yog siv dav vim qhov yooj yim ntawm kev tsim ua ntau yam duab.
W. H. Hatfield tsim cov khoom sib xyaw ntawm 304 stainless hlau hauv xyoo 1924. Qhov no tau ua lag luam siv lub npe lag luam "Staybrite 18/8" thaum lub sijhawm ntawd; Lub npe no qhia txog cov ntsiab lus ntawm chromium thiab npib tsib xee. Txawm li cas los xij, sab nraum Tebchaws Meskas, cov hlau no feem ntau hu ua A2 stainless hlau. Thaum nws los txog rau kev lag luam cookware, nws yog hu ua 18/8 stainless hlau. Ntxiv nrog rau chromium thiab npib tsib xee, 304 stainless hlau muaj cov pa roj carbon, silicon, manganese, phosphorous, thiab sulfur zoo li.
Muaj ntau qhov kev siv ntawm 304 stainless hlau: kev tsim khoom ntawm ntau yam khoom noj thiab cov khoom siv xws li cov ntsia hlau, cov khoom siv, cov khoom siv, thiab lub tsheb headers, hauv architecture rau sab nrauv accents nrog rau cov dej thiab hluav taws, thiab lwm yam. Daim ntawv stainless hlau no feem ntau tseem ceeb hauv kev tsim cov khoom siv coil rau cov vaporizers.
202 Stainless Hlau yog dab tsi?
202 stainless hlau yog hom tsis tshua muaj cov hlau tsis muaj hlau uas ua rau xeb. Nws kuj yog nyob rau hauv cov chav kawm austenitic ntawm hlau alloys. Yog li ntawd, lub microstructure ntawm no stainless hlau alloy muaj lub ntsej muag-centered cubic qauv. 202 stainless hlau muaj manganese thiab nitrogen hauv nws cov qauv tshuaj, uas yog lwm txoj hauv kev zoo rau cov ntsiab lus siab nickel hauv 304 stainless hlau qauv. Txawm li cas los xij, 202 stainless hlau tseem muaj qee qhov nickel.
Daim ntawv no ntawm cov hlau tsis muaj hlau yog qhov tseem ceeb hauv kev tsim cov khoom siv hauv chav ua noj, cov khoom siv ua noj, hose clamps, cov khoom siv hauv tsev noj mov, tsheb txiav, tsheb ciav hlau bogeys, trailer, thiab qee qhov kev kho vaj tse xws li qhov rais thiab qhov rooj.
Zoo ib yam li feem ntau ntawm cov austenitic alloys, 202 stainless hlau tso cai rau peb los txuas nws los ntawm cov txheej txheem sib xyaw ua ke. Tsis tas li ntawd, nws tso cai rau kev siv cov kev tiv thaiv rau cov txheej txheem vuam. Txawm li cas los xij, nws tsis tsim nyog siv txoj kev vuam oxyacetylene rau cov hlau tsis zoo no.
Qhov txawv ntawm 304 thiab 202 Stainless Hlau yog dab tsi?
304 thiab 202 stainless hlau yog ob hom stainless hlau hlau alloys. Qhov sib txawv tseem ceeb ntawm 304 thiab 202 stainless hlau yog tias 304 stainless hlau muaj cov ntsiab lus siab ntawm chromium thiab npib tsib xee, uas ua rau nws tsis tshua muaj xeb, thaum 202 stainless hlau muaj tsawg chromium thiab npib tsib xee, uas ua rau nws yooj yim dua rau xeb. rusting.
Cov ntawv qhia hauv qab no nthuav tawm qhov sib txawv ntawm 304 thiab 202 stainless hlau hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – 304 vs 202 Stainless hlau
Stainless hlau hlau alloys yog chromium-muaj hlau alloys. 304 thiab 202 yog ob hom stainless hlau. Qhov sib txawv tseem ceeb ntawm 304 thiab 202 stainless hlau yog tias 304 stainless hlau muaj cov ntsiab lus siab ntawm chromium thiab npib tsib xee, uas ua rau nws tsis tshua muaj xeb, thaum 202 stainless hlau muaj tsawg chromium thiab npib tsib xee, uas ua rau nws yooj yim dua rau xeb. rusting.
