Corrosion Resistant AlloyMonel 400Round Nickel Alloy Yeeb Nkab

Kev piav qhia
Monel 400(UNS N04400/2.4360) yog nickel-tooj ​​liab alloy nrog lub zog siab thiab ua haujlwm zoo rau ntau yam xov xwm xws li dej hiav txwv, dilute hydrofluoric thiab sulfuric acids, thiab alkalies.
Monel 400 muaj txog 30-33% tooj liab nyob rau hauv nickel matrix muaj ntau yam zoo sib xws ntawm kev lag luam ntshiab npib tsib xee, thaum txhim kho rau ntau lwm tus. Ntxiv ntawm ib co hlau ho txhim kho qhov tsis kam mus rau cavitation thiab yaig nyob rau hauv condenser raj daim ntaub ntawv. Cov kev siv tseem ceeb ntawm Monel 400 yog nyob rau hauv cov xwm txheej ntawm kev khiav ceev thiab yaig xws li hauv cov kiv cua shafts, kiv cua, twj tso kua mis-impeller hniav, casings, condenser raj, thiab tshav kub exchanger raj. Corrosion tus nqi hauv cov dej hiav txwv txav feem ntau tsawg dua 0.025 mm / xyoo. Lub alloy muaj peev xwm pit nyob rau hauv stagnant seawater, txawm li cas los, tus nqi ntawm kev tawm tsam yog considerably tsawg tshaj li nyob rau hauv kev lag luam ntshiab alloy 200. Vim nws siab nickel cov ntsiab lus (kwv yees li 65%) cov hlau feem ntau tiv thaiv chloride kev nyuaj siab corrosion cracking. Qhov dav dav corrosion kuj ntawm Monel 400 hauv nonoxidizing ntxhia acids zoo dua piv rau npib tsib xee. Txawm li cas los xij, nws raug kev txom nyem los ntawm qhov tsis muaj zog ntawm qhov ua rau pom kev tsis zoo heev rau oxidizing media xws li ferric chloride, cupric chloride, chlorine ntub dej, chromic acid, sulfur dioxide, lossis ammonia. Nyob rau hauv unaerated dilute hydrochloric thiab sulfuric acid tov cov alloy muaj txiaj ntsig zoo tiv thaiv mus txog qhov siab ntawm 15% ntawm chav tsev kub thiab txog li 2% ntawm qhov kub me ntsis, tsis tshaj 50 ° C. Vim yog cov yam ntxwv tshwj xeeb no, Monel 400 tsim los ntawm NiWire kuj tseem siv rau hauv cov txheej txheem uas cov kuab tshuaj chlorinated tuaj yeem tsim hydrochloric acid vim hydrolysis, uas yuav ua rau tsis ua haujlwm hauv cov qauv stainless hlau.
Monel 400 muaj zoo corrosion kuj ntawm ambient kub rau tag nrho cov HF concentration thaum tsis muaj huab cua. Aerated kev daws teeb meem thiab kub siab dua ua rau tus nqi corrosion. Cov hlau yog raug rau kev nyuaj siab corrosion tawg nyob rau hauv moist aerated hydrofluoric los yog hydrofluorosilic acid vapor. Qhov no tuaj yeem txo qis los ntawm deaeration ntawm ib puag ncig lossis los ntawm kev ntxhov siab tshem tawm ntawm cov khoom hauv nqe lus nug.
Cov ntawv thov yog cov khoom siv valve thiab twj tso kua mis, kiv cua shafts, marine fixtures thiab fasteners, cov khoom siv hluav taws xob, cov khoom siv tshuaj lom neeg, cov roj av thiab cov tso tsheb hlau luam, cov khoom siv roj av, cov khoom siv hluav taws xob boiler thiab lwm yam khoom siv hluav taws xob.
