Dab tsi yog steel tooj 1.4301 SS yeeb nkab?
Cov hlau tooj 1.4301 yog tus qauv European (EN) tsim rau feem ntau austenitic stainless hlau, dav hu ua AISI 304, Qib 304, lossis X5CrNi18-10, muaj txog 18% chromium thiab 10% npib tsib xee, muab kev tiv thaiv zoo corrosion, formability, thiab weldability, dav siv hauv chav ua noj.
1.4301 stainless hlau txias dov yeeb nkabCov yam ntxwv tseem ceeb:
Hom: Austenitic Stainless Hlau.
Muaj pes tsawg leeg: Roughly 18% Chromium (Cr) thiab 10% Nickel (Ni).
Cov qauv tsim: 1.4301 (EN), X5CrNi18-10 (Alphanumeric), AISI 304, SUS304 (Japanese).
Khoom: Zoo corrosion kuj, zoo heev formability, weldability, thiab toughness, txawm nyob rau hauv qis kub.
Sib nqus: Tsis yog- sib nqus nyob rau hauv lub xeev annealed (softened) tab sis tuaj yeem ua tau me ntsis sib nqus tom qab ua haujlwm txias lossis vuam.
Daim ntaub ntawv: Dav siv rau hauv chav ua noj dab dej, khoom noj khoom haus, khoom vaj khoom tsev, tso tsheb hlau luam, kav dej, thiab kev tsim khoom dav dav.
1.4301 stainless hlau Chemical Composition (wt.%)
Ua raws li EN 10088-2 tus qauv, nrog 18.0–20.0% Cr, 8.0–10.5% Ni, Tsawg dua lossis sib npaug rau 0.08% C, Tsawg dua lossis sib npaug li 1.00% Si thiab Tsawg dua lossis sib npaug li 2.00% Mn; the chromium-nickel alloy system forms a dense oxide film on the surface, which is the core basis for its corrosion resistance.
1.4301 stainless hlau Mechanical Properties (ntawm chav tsev kub)
Tensile zog: Ntau dua los yog sib npaug rau 520 MPa
Yield zog: Ntau dua los yog sib npaug rau 205 MPa
Elongation: Ntau dua lossis sib npaug li 40%
Brinell hardness (HB): Tsawg dua lossis sib npaug rau 201
Dab tsi yog cov khoom ntawm 1.4301 SS round yeeb nkab?
Corrosion Resistance
1.4301 stainless hlau seamless raj pom zoo heev zoo corrosion kuj nyob rau hauv qaug zog acid, qaug zog alkali, thiab nruab nrab ntsev ib puag ncig; Tom qab 144 teev nyob rau hauv 5% NaCl nruab nrab ntsev tshuaj tsuag, tus nqi corrosion yog tsawg dua los yog sib npaug rau 0.005 mm / a, uas yog ntau dua 20 npaug qis dua li cov pa roj carbon zoo tib yam; nws muaj corrosion kuj zoo rau atmospheric, dej tshiab, thiab zaub mov- qib xov xwm, tab sis tsis pom zoo rau ntev - siv nyob rau hauv dej hiav txwv los yog siab - chloride ib puag ncig.
High -Tsub Ua Haujlwm
1.4301 stainless hlau kub- dov cov raj tuaj yeem siv tsis tu ncua ntawm qhov kub txog li tsawg dua lossis sib npaug li 870 degree, thiab rau lub sijhawm luv ntawm qhov kub txog li 925℃; Thaum qhov kub thiab txias qis dua 400 degree, cov neeg kho tshuab lub zog tuav tus nqi siab dua 80%, ua rau nws tsim nyog rau nruab nrab thiab qis - kub hloov pauv thiab cov kav dej.
Vuam Performance
1.4301 stainless hlau raj txhawb nqa cov txheej txheem vuam xws li TIG thiab MIG; Qhov zoo tshaj plaws vuam tam sim no yog 120-140A, thiab lub zog tensile tuav tus nqi ntawm cov vuam yog ntau dua los yog sib npaug rau 95%; Tsis muaj preheating yuav tsum tau thaum lub sij hawm vuam, thiab tom qab vuam kev ua tau zoo yog ruaj khov.
Machining Performance
1.4301 txias- ua haujlwm stainless hlau raj muaj qhov ua haujlwm txias txias thiab ua haujlwm zoo, nrog lub thickness kam rau ua ± 0.05 hli; precision machining xws li txiav, tapping, thiab polishing tuaj yeem ua raws li daim ntawv thov.
Hygienic thiab Environmental Performance
1.4301 sanitary stainless hlau raj ua tau raws li FDA thiab EU (EC) Tsis muaj 1935/2004 zaub mov- cov qauv kev sib cuag, tsis yog- tsis muaj tshuaj lom thiab muaj ntxhiab tsw, tsis tso cov tshuaj phem, thiab tsim nyog rau cov khoom noj, dej haus, thiab cov kav dej tshuaj.
Nrog 18 xyoo ntawm kev paub nyob rau hauv cov yeeb nkab tsim, GNEE yog ib tug trustworthy tsum ntawm stainless hlau kav. Lub Hoobkas tsis tsuas yog tsim cov qauv- loj annealed steel kav, tab sis kuj muab cov kav dej txuas ntxiv ntawm 18 meters thiab 25 meters kom tau raws li qhov xav tau ntawm nws cov neeg siv khoom. Lub Hoobkas tau nruab nrog cov chaw xws li txias dov mills, qhov cub tsis muaj pa taws, lub tank pickling, ultrasonic eddy tam sim no tu tshuab, thiab lub cev thiab tshuaj lom neeg lub chaw soj nstuam.
GNEE muaj cov txheej txheem tswj xyuas kev ua tau zoo nyob rau hauv qhov chaw, ntiav cov kws tshaj lij MTSCO cov neeg soj ntsuam cov ntawv pov thawj thoob plaws hauv qib ua ntej - ntau lawm, ntau lawm, thiab tom qab- cov theem tsim khoom, yog li muab cov neeg siv khoom muaj kev ruaj ntseg khoom zoo. Tsis tas li ntawd, GNEE cov khoom yog ISO, PED, thiab AD2000 tau ntawv pov thawj, qhia nws lub zog thiab lub koob npe nrov hauv qhov zoo.
