Tso lus

1.4841 stainless hlau, feem ntau hu ua 310 los yog UNS S31000, yog siab -kub austenitic stainless hlau nrog tshwj xeeb oxidation tsis kam thiab zoo creep zog ntawm qhov kub thiab txias. Nrog nws cov chromium siab (24-26%) thiab npib tsib xee (19{10}}22%) cov ntsiab lus, nws muaj kev tiv thaiv zoo tshaj plaws rau scaling thiab oxidation hauv kev pabcuam txuas mus txog 1100 degree, ua rau nws yog ib qho ntawm cov khoom siv dav tshaj plaws rau kev siv kub. Nws yog cov khoom ntawm kev xaiv rau cov khoom siv hluav taws xob, cov khoom siv kho cua sov, thiab cov txheej txheem kub kub uas yuav tsum tau muaj qhov siab tshaj plaws oxidation.

Exceptional High -Tub kub Oxidation Resistance:Ua kom ruaj khov, ua raws li chromium oxide txheej uas tiv thaiv kev ntsuas thiab oxidation hauv kev pabcuam txuas mus txog 1100℃(2010℃F) thiab kev pabcuam cuam tshuam txog 1050℃(1920℃F).

Zoo Creep thiab Repture Strength:Ua kom muaj kev ncaj ncees nyob rau hauv cov khoom siv thauj khoom ntawm qhov kub siab, haum rau kev thauj khoom -cov kabmob siab - qhov kub thiab txias.

Zoo Sulfur Resistance:Ua tau zoo nyob rau hauv sulfur- muaj cov cua, qhov twg ntau lwm yam stainless hlau yuav sai sai degrade.

Zoo Thermal Fatigue Resistance:Withstands rov ua cua sov thiab cua txias mus yam tsis muaj qhov tseem ceeb degradation.

Thaum tshav kub kub kho Furnaces:Radiant tubes, muffles, retorts, baskets, furnace rolls, thiab annealing npog.

Tshuaj thiab Petrochemical:Reformers, pyrolysis raj, thiab catalyst txhawb cov phiaj hauv siab -cov txheej txheem kub.

Kev tsim hluav taws xob:Boiler Cheebtsam, kev txhawb nqa superheater, thiab cov cua sov rov qab.

Glass & Ceramic Manufacturing:Kub tuav cov khoom siv thiab cov rooj tog zaum.

Kev lag luam cement:Preheater cyclones thiab ducting.

Waste Incineration:Combustion Chambers thiab cov cua kub exchangers.

Vuam Filler Hlau:Siv rau siab - daim ntawv thov kub thiab koom nrog cov hlau tsis sib xws.

310 muaj cov ntsiab lus carbon ntau dua (tsawg dua lossis sib npaug li 0.20%) piv rau 310S (tsawg dua lossis sib npaug li 0.08%), muab lub zog nkag tau zoo dua ntawm qhov kub siab, tab sis qis dua weldability. 310S yog qhov qis- carbon version nyiam rau cov ntawv thov welded qhov twg muaj kev txhawj xeeb. Piv rau 309 (23% Cr, 13% Ni), 310 muaj ntau dua chromium thiab npib tsib xee cov ntsiab lus, muab nws superior oxidation tsis kam thiab siab tshaj qhov kev pab kub (1100℃vs . 1000 degree). 310 yog xaiv rau qhov xav tau tshaj plaws siab - kub daim ntawv thov, thaum 3016 lwm yam kev siv tsis zoo los yog raug xaiv.

310S (tsawg carbon) yog qhov zoo dua rau cov ntawv thov welded kom tsis txhob hnov qab

Muab cov hlau sib txuam (ER310 rau TIG / MIG, E310-16 rau SMAW) raug pom zoo

Rau vuam sib txawv ntawm cov hlau, 310 muab tub lim yuav siv tau rau siab -kev siv kub

Pom zoo cua sov input: 0.5-2.0 kJ / mm

Interpass kub yuav tsum khaws cia qis dua 150 degree

Tom qab-weld heat treatment feem ntau tsis tas yuav tsum tau tab sis tej zaum yuav muaj txiaj ntsig zoo rau cov ntu hnyav

Tshaj tawm -welding tu thiab pickling / passivation yog pom zoo rau qhov zoo tshaj plaws corrosion kuj

Thaum 310 muaj qhov tshwj xeeb siab - qhov ua haujlwm kub, nws muaj ntau qhov kev txwv:

Cov ntsiab lus carbon siab tuaj yeem ua rau rhiab heev yog tias welded tsis muaj kev saib xyuas zoo

Tsis haum rau aqueous corrosion daim ntawv thov qhov twg lwm qib ua tau zoo dua

Cov ntsiab lus nickel siab ua rau nws kim dua cov qib qis alloyed

Nws tuaj yeem ua rau lub sijhawm sigma embrittlement yog tuav hauv 650-900℃ntau rau lub sijhawm ntev

Kev txwv tsis pub muaj kev txo qis hauv huab cua thiab halogen gases

Tsawg zog ntawm chav tsev kub piv rau nag lossis daus-qib hardening

GNEE Steel muab cov nqi siab siab - kub qib 310 (1.4841) stainless hlau hauv phaj, ntawv, bar, yeeb nkab, thiab cov ntaub ntawv haum rau qhov xav tau tshaj plaws rau qhov cub thiab cov txheej txheem siv. Peb muab cov ntaub ntawv pov thawj tag nrho (EN 10204 3.1) thiab kev txhawb nqa suav nrog kev txiav, kev tsim, thiab kev pabcuam vuam. Yog tias koj muaj kev xav tau, thov koj xav tiv tauj peb.
