Dab tsi yog 1.4541 stainless hlau?
1.4541 stainless hlau (tseem hu ua AISI 321 lossis X6CrNiTi18-10) yog titanium-stabilized austenitic stainless hlau dav siv nyob rau hauv siab - kub thiab corrosion- tiv taus ib puag ncig. Vim nws zoo heev tsis kam mus rau carbide nag lossis daus thiab siab -kub oxidation, nws yog ib qho ntawm cov ntaub ntawv txhim khu kev qha tshaj plaws rau kev pabcuam mus sij hawm ntev ntawm qhov kub ntawm 600-870 degree.
Vim li cas 1.4541 ua tau zoo nyob rau hauv siab -cov ntawv thov kub?
1.4541 tuav lub zog ruaj khov ntawm Tsawg dua lossis sib npaug li 870℃(qhov dav dav hauv chav tsev kub tensile lub zog ntawm kwv yees li 500-750 MPa, thiab siab - kub creep zog tau zoo dua li ntawm kwv yees li 20-30% piv rau 304), thiab pom zoo oxidation tsis kam. Lub Cr₂O₃ tiv thaiv zaj duab xis tsim tom qab ntev- lub sij hawm raug huab cua ntawm 800℃yog denser, nrog ib tug qis oxidation tus nqi tshaj 304. Tsis tas li ntawd, nws muaj ib tug tsawg txaus ntshai ntawm carbide nag lossis daus thaum vuam thiab muaj peev xwm tiv taus tas mus li thermal cycling yam tsis tsim riam-zoo li cov yeeb nkab cua sov, ua rau lub cav tawg, ua rau lub tshuab ua kom sov. siab - qhov kub ntawm lub cub tawg.
Dab tsi yog cov ntawv thov ntawm 4541 stainless hlau hauv qhov kub thiab txias?
1.4541 stainless hlau yog dav siv nyob rau hauv kev lag luam uas yuav tsum tau ob qho tib si corrosion kuj thiab ntev -lub sij hawm siab - kub durability:
Qhov cub Cheebtsam:rauv tub raj, tshav kub shields, burner qhov chaw

Qhov ntsuas kub ntawm 1.4541 yog dab tsi?
Qhov kub txwv rau 1.4541 (tseem hu ua AISI 321) yog mus txog 900℃hauv kev ua haujlwm tsis tu ncua hauv huab cua rau oxidation tsis kam, tab sis kev pabcuam txuas ntxiv feem ntau txwv rau 550℃vim txo cov khoom siv kho tshuab. Cov khoom muaj kev tiv thaiv zoo rau intergranular corrosion tom qab vuam, txawm tias tom qab raug kub ntawm 425℃thiab 850 degree, ua rau nws haum rau siab - kub daim ntawv thov xws li vuam Cheebtsam.
Puas yog 1.4541 zoo dua 304 rau qhov kub thiab txias?
Yog lawm, 1.4541 (tseem hu ua AISI 321) yog qhov zoo dua li 304 (1.4301) rau siab -kev siv kub, tshwj xeeb tshaj yog cov uas cuam tshuam nrog vuam. Qhov no yog vim 1.4541 ruaj khov nrog titanium, uas tiv thaiv kev tsim ntawm chromium carbide ntawm qhov kub thiab txias ntawm 425℃thiab 815 degree, yog li tsis txhob cuam tshuam intergranular corrosion.
Puas yog 1.4541 tiv thaiv corrosion hauv tshuaj lom neeg ib puag ncig?
Yog lawm, 1.4541 (tseem hu ua AISI 321) stainless hlau tiv thaiv corrosion zoo nyob rau hauv ntau qhov chaw tshuaj, tshwj xeeb tshaj yog cov uas muaj feem xyuam rau atmospheric tej yam kev mob, dej tshiab, thiab tej yam organic los yog nitric acids. Txawm li cas los xij, nws tsis pom zoo rau ib puag ncig uas muaj cov tshuaj chlorides siab, xws li dej hiav txwv, vim nws tsis zoo rau pitting thiab crevice corrosion nyob rau hauv cov mob no.
1.4541 stainless hlau nqi npaum li cas ib kg?
Vim muaj kev hloov pauv hauv ntiaj teb cov khoom siv raw cov nqi (nickel, chromium), tus nqi ntawm 1.4541 tseem tsis hloov pauv.
Tus Nqi Ua Lag Luam Zoo (rau kev siv nkaus xwb):
Phaj: $ 2.6 - $ 3.3 / kg
Yob: $ 2.5 - $ 3.1 / kg
Cov yeeb nkab: $ 3.2 - $ 4.5 / kg
Round Bar: $ 3.0 - $ 4.0 / kg
Tus nqi nce tsis ntev los no: Rov qab los ntawm tus nqi npib tsib xee. Muaj zog thov los ntawm kev lag luam petrochemical thiab rauv; Q4 ntau lawm poob. Kev pom zoo: Cov neeg yuav khoom yuav tsum tso cov xaj kom ntxov kom tsis txhob nce nqi.
