Dab tsi zoo yog 201 stainless hlau?
Raws li peb txhua tus paub, SAE 304 stainless hlau yog ntau yam stainless hlau siv nyob rau hauv ntau yam lag luam, sib nrug los ntawm nws "kwv tij txheeb ze" SAE 316 stainless hlau. Txawm li cas los xij, cov ntsiab lus siab nickel hauv SAE 304 alloy ua rau hom stainless hlau no kim heev, yog li cov engineers qee zaum siv lwm txoj kev pheej yig dua: SAE 201 stainless hlau.
Hauv phau ntawv qhia no, peb yuav tham txog Stainless Steel 201 vs. Stainless Steel 304, lawv qhov sib txawv, zoo sib xws, thiab lawv daim ntawv thov.
Dab tsi yog qhov txawv ntawm SAE 201 thiab SAE 304 stainless hlau?
Ntxiv nrog rau cov tshuaj muaj pes tsawg leeg sib txawv uas peb yuav tham tom qab, muaj qee qhov yuav luag tsis pom qhov sib txawv ntawm ob lub stainless hlau no. Uas tau hais tias, SAE 201 zoo li tsaus me ntsis piv rau SAE 304 vim tias feem ntau cov ntsiab lus qis chromium thiab cov ntsiab lus manganese ntau dua.
Txawm li cas los xij, raws li tau hais los saum no, qhov sib txawv no tsis tshua pom, thiab koj yuav tsum tau tso ob cov ntaub ntawv stainless hlau nyob ib sab rau lawv kom pom tseeb.
tshuaj muaj pes tsawg leeg
Ob qib ntawm stainless hlau muaj cov ntsiab lus siab chromium thiab npib tsib xee. Txawm li cas los xij, lawv yog ib pawg sib txawv kiag li, thiab qhov ntawd yog qhov ua rau lawv sib txawv. SAE 304 yog austenitic stainless hlau uas muaj 18% mus rau 20% chromium, 0.08% carbon, thiab 8% -10% npib tsib xee. Cov hlau no yog chromium-nickel alloy.
Txawm li cas los xij, SAE 201 stainless hlau belongs rau pawg chromium-manganese-nickel, uas txhais tau hais tias cov ntsiab lus ntawm manganese kuj siab thiab cov ntsiab lus npib tsib xee kuj tsawg. SAE 201 yog austenitic stainless hlau nrog cov ntsiab lus siab carbon ntawm 0.15% thiab cov ntsiab lus tsis tshua muaj nickel ntawm 3.5% txog 5.5%. Nws muaj kwv yees li ntawm 16-18% chromium thiab 5.5% mus rau 7.5% manganese.
Corrosion kuj
Ob leeg SAE 304 thiab SAE 201 tau txais lawv cov kev tiv thaiv corrosion los ntawm lawv cov ntsiab lus chromium thiab npib tsib xee. Txawm li cas los xij, SAE 304 muaj cov feem pua ntawm ob qho tib si alloying ntsiab nyob rau hauv qhov kev tso cai, uas muab cov alloy nrog zoo corrosion kuj.
Hmoov tsis zoo, SAE 201 muaj tsawg dua ntawm cov alloying cov ntsiab lus, uas ua rau nws tsis tshua muaj corrosion resistant SAE 304. Lub tom kawg yog tsuas yog siv nyob rau hauv kev tu cev xws li cov zaub mov qib ntim thiab stainless hlau dej fwj vim nws zoo corrosion kuj.
Txawm li cas los xij, qee lub raj mis dej insulated siv SAE 201 hauv lawv cov khoom siv stainless hlau, uas yog daim ntawv thov tsis txaus thiab tej zaum txawm tias siv cov khoom siv tsis raug.
lub cev muaj zog
SAE 201 stainless hlau yog cov tawv tawv dua SAE 304, thaum SAE 304 muaj cov khoom siv kho tshuab zoo dua thiab qaug zog dua li SAE 201. Txawm li cas los xij, qhov kev thov ntawm SAE 201 nyob rau hauv nws cov nqi pheej yig, kev ua tau zoo hauv huab cua txias thiab kev siv sab hauv tsev xws li qhov rooj tuav lossis workpiece tuav cov khoom xws li jigs thiab fixtures.
