Cov yam ntxwv tseem ceeb thiab kev siv ntawm 1.4464 / Super Duplex 2506
Exceptional Corrosion Resistance:Muaj tus lej Pitting Resistance siab heev (PREN> 40), muab kev tiv thaiv zoo tshaj rau pitting, crevice corrosion, thiab kev ntxhov siab corrosion tawg hauv cov chloride kub -laden ib puag ncig.
Muaj zog heev:Muab lub zog tawm los kwv yees li ob npaug ntawm cov qauv austenitic steels, ua kom muaj qhov hnyav thiab txo nqi hauv cov hlab ntsha siab thiab cov khoom siv.
Zoo Erosion thiab hnav tsis kam:Cov theem ferritic ua rau muaj kev tiv thaiv zoo tiv thaiv kev yaig -corrosion thiab abrasive hnav.
Cov ntawv thov tseem ceeb:
Subsea & Offshore:Christmas ntoo, manifolds, flowlines, thiab umbilicals nyob rau hauv dej tob thiab roj ntau lawm.
Kev ua tshuaj lom neeg:Reactors, kub exchangers, thiab kav dej rau corrosive acids thiab chlorides heev.
Desalination & FGD Nroj Tsuag:High -siab RO membranes, evaporator tubes, thiab scrubber systems.
Pulp & Ntawv Kev Lag Luam:Digesters thiab bleaching khoom.
Super Duplex 2506 (1.4464) txawv ntawm Super Duplex 2507 (1.4410) li cas?
Thaum ob qho tib si yog qib super duplex, 2506 feem ntau muaj qis dua nickel thiab molybdenum cov ntsiab lus piv rau 2507, uas tuaj yeem ua rau qis qis qis hauv qee qhov chaw hnyav heev. Txawm li cas los xij, 2506 tseem muaj kev ua tau zoo heev thiab feem ntau raug xaiv rau cov ntawv thov uas yuav tsum muaj qhov sib npaug ntawm tus nqi thiab kev ua tau zoo . 2507 feem ntau suav tias yog tus qauv ntsuas rau super duplex corrosion kuj.
Dab tsi yog qhov tseem ceeb rau kev vuam Super Duplex 2506 stainless hlau?
Vuam 2506 yuav tsum muaj kev tswj xyuas nruj kom tswj tau qhov zoo tshaj plaws 50/50 ferrite-austenite tshuav nyiaj li cas hauv cov hlau vuam thiab cua sov- thaj chaw cuam tshuam (HAZ). Cov kev coj ua tseem ceeb suav nrog kev siv ntau tshaj -alloyed muab tub lim hlau (xws li, 25.10.4.L), kev tswj xyuas cov cua sov kom tsis txhob muaj cov ferrite ntau dhau los yog nag lossis daus ntawm nkig intermetallic theem, thiab xyuas kom muaj cov pa tiv thaiv txaus (feem ntau Ar + 30% N2) kom tswj cov qib nitrogen. Tom qab-welding tus nqi yuav tsum tau tswj, thiab cov khoom yuav tsum tsis txhob nyob rau hauv qhov kub thiab txias (kwv yees{14}} degree) rau ncua sij hawm.
