Qhov txawv ntawm Monel 500 thiab Monel 400 yog dab tsi?
I. Txheej txheem cej luam
Alloy 400 yog ib qho kev daws teeb meem bimetallic alloy nrog qhov zoo ntawm lub zog siab, zoo toughness, thiab kuj mus rau ntau yam corrosive ib puag ncig nyob rau hauv ib tug dav kub ntau yam. Kev ua haujlwm kub ntawm nickel tooj liab 400 tuaj yeem siab txog 427 degree. Nyob rau hauv ib puag ncig sulfur oxidizing, kev ua haujlwm kub tuaj yeem ncav cuag 538 degree. Tsis tas li ntawd, cov khoom siv kuj nthuav tawm cov khoom siv kho tshuab zoo heev hauv cov cheeb tsam sub-zero. Cov khoom siv ua haujlwm tau txais txiaj ntsig, thiab kev ua haujlwm txias tuaj yeem ntxiv dag zog rau cov khoom siv.
daim ntawv thov
Alloy 400 yog dav siv, feem ntau nyob rau hauv marine thiab tshuaj ua ib puag ncig. Cov khoom siv tseem ceeb muaj xws li li qub, twj tso kua mis, twj tso kua mis, lub twj tso kua mis, cov twj tso kua mis, cov khoom siv marine thiab fasteners, cov khoom siv tshuaj lom neeg, cov thooj voos kheej kheej, cov kav dej, cov roj av distillation, cov thooj voos kheej kheej, cov kav dej, boiler feed water heaters, heat exchangers, deaeration heaters, etc.
Corrosion kuj
Alloy 400 yuav tsis tsim chloride ion kev nyuaj siab corrosion cracking. Feem ntau, Alloy 400 muaj qhov zoo corrosion kuj nyob rau hauv kev txo qhov chaw, tab sis muaj tsis zoo corrosion kuj nyob rau hauv oxidizing ib puag ncig.
Nyob rau hauv ib txwm kub thiab kub ib puag ncig, Alloy 400 yog resistant rau ntau yam corrosion, nrog rau feem ntau alkaline tshuaj, ntsev, dej (xws li brine), zaub mov, organic tshuaj, thiab lwm yam.
Tab sis cov khoom no tsis tuaj yeem siv nrog cov muaj zog oxidizing acids xws li nitric acid thiab nitrous acid
Alloy 400 tuaj yeem tiv taus sulfuric acid hauv cov ntsiab lus tsawg dua 80% thiab hydrochloric acid hauv cov ntsiab lus tsawg dua 20%.
Cov xov xwm uas tsis muaj teeb meem rau Alloy 400 tuaj yeem corrode Alloy 400 yog tias lawv muaj oxide impurities, xws li ferric chloride, ferric sulfate, chromate, nitrate, peroxide thiab cupric ntsev.
