UNR UNS UNR UNS UNR UNL UNR UNR UNR UNR UNR UNR UNR UNR UNR UNR UNR UNR UNR UNR UNR UNR UNR UNR TSIS ZOO (ALLOY 255, DIN 1.4507, F61)yog qhov ua tau zoo duplex stainless hlau khoom. Vim nws cov kws kho mob zoo heev thiab corrosion tsis kam, nws yog dav siv hauv petrochemical, marine engineering, cov khoom siv hluav taws xob thiab lwm thaj chaw.
ASTM A790 UNSIVE S32550 Super Dupled thiab Seamless Tube Chaw Tsim Tshuaj, Chaw Muag Khoom
Raws li ib tug ntseeg siab rau stockist thiab exporter nrog kaum xyoo thiab ib nrab ntawm kev paub thoob ntiaj teb, HT cov yeeb nkab muaj cov khoom siv dav dav:ASTM A790 UNSIVE S32550 kav, cov ntawv txheeb, cov kab sib cais, ntxiv rau qhov ntsuas hluav taws xob, flanges, thiab txuas txuas.Hu rau peb pab neegpub dawb, customized quotes thiab cov ntawv qhia khoom khoom.
Tshuaj lom neeg muaj pes tsawg leeg ntawm F61
S3255 {5}} me steel muaj txog 25% chromium, 6.5% npib tsib, 3% molybdenum thiab 0.2% nitrogen. Lub siab chromium cov ntsiab lus muab cov khoom siv corrosion tsis kam lees qhov pitting thiab kev sib ntxiv los txhim kho lub zog, tab sis kuj txhawb kev tsim ntawm Austenite theem.
Cov Khoom Siv Neeg Kho Tshuab ntawm 1.4507
Lub zog tensile ntawm S32550 yeeb nkab kev kho mob tuaj yeem mus txog {} mpa}} mpa mpa cia siab dua lossis sib npaug, thiab lub elongation tseem nyob saum 25%. Nws lub zog yog ob zaug uas muaj cov hlau tsis muaj txiaj ntsig ntawm cov hlau stainless, thaum tswj hwm kev cuam tshuam zoo nyuaj.
Super Duplex 255 Yeeb Corrosion Kuj
Lub corrosion resistance qhia tau ntau yam xwm txheej zoo. Hauv nruab nrab-concentration sulfuric acid ib puag ncig hauv qab 800mm / xyoo, nws lub corrosion ib puag ncig, nws cov corrosion, nws qhov tseem ceeb punting kub, qhov ntsuas qhov tseem ceeb tshaj 60 degree.
tsim cov txheej txheem ntawm uns s32550
Qhov kub ua qhov kub yuav tsum tau tswj nyob rau hauv thaj tsam ntawm 1050-1150 degree, thiab tus nqi dej txias, thiab cov dej txias rau 50 degree / s los tiv thaiv cov dej nag ntawm σ theem. 22.8.3L cov khoom siv vuam yog pom zoo rau vuam, thiab cov ntsuas kub cuam tshuam yog txwv tsawg dua li 150 degree.
255 yeeb nkab kev sib piv sib piv nrog cov khoom sib tw
Piv nrog 2205 duplex steel (S32205):S32550 muaj tus nqi siab dua (38-40}
Piv nrog ustenitic stainless hlau 316L:S32550 muaj cov txiaj ntsig ib lub zog (ntau dua los yog sib npaug ntawm 550MPA) uas yog ntau dua li ntawm 200 degree kom txo qis cov haujlwm ua haujlwm hnyav.
Piv nrog nickel-based alloys:Hauv cov dej hiav txwv ib puag ncig, cov corrosistance ntawm S32550 yog piv rau qhov ntawm 625 alloy, tab sis tus nqi tsuas yog 1/3 ntawm tus kawg, ua tau zoo.
