Nyob rau hauv lub ntiaj teb ntawm siab - performance performance performance performances, qhov uas muaj zog, monel {-}}}}} Tested Championed Champion. Ntawm [koj lub npe lub Hoobkas], ib qho chaw tsim khoom lag luam ntawm cov hlau tshwj xeeb thiab cov nickel alloys, peb nkag siab cov ntaub ntawv tseem ceeb ua si hauv koj txoj kev vam meej. Tsab ntawv no rho tawm tob rau dab tsi monel 400 yog, vim li cas nws txuas ntxiv mus daws tau cov kev sib tw ua kom daws cov kev nyuaj.
Monel 400 Tshuaj Muaj Tshuaj
Monel 400 (tsis muaj N04400) yog cov khoom -}}}}}} tooj liab alloy. Nws muaj pes tsawg leeg yog nws lub zog:
- Nickel (NI): 63% yam tsawg kawg nkaus (feem ntau 63-70%) - muab cov kev ua kom haum corrosion tsis kam thiab ductility inerent rau neeloys alloys.
- Tooj liab (Cu): 28-34% - txhim kho kom muaj kev txo ib puag ncig, cov kua qaub zoo li sulfuric thiab hydibrofic, thiab pab txhawb rau lub zog siab.
- Hlau (FE): 2.5% Max - tam sim no los ua cov khoom seem.
- Manganese (MN): 2.0% Max - AIDS hauv Deagidation thaum lub caij melting thiab ua rau muaj zog.
- Cov pa roj carbon (c): 0.3% Max - tswj tau los tswj hwm corrosion thiab weldability.
- Silicon (Si): 0.5% MAX, SULFUR: 0.024% Max - feem ntau khaws qis qis.
Tsim los ntawm International Nickel tuam txhab (Inco) thaum ntxov xyoo pua 2000, Monel 400 derives nws lub npe los ntawm lub tuam txhab tus thawj tswj hwm thaum lub sijhawm, Amebrose Monell. Nws qhov kev ua tiav tau zoo heev los ntawm nws cov kev sib xyaw ua ke ntawm cov khoom, tshwj xeeb hauv cov qauv sib tw uas cov qauv stainless hlau (zoo li 304 lossis 316) poob luv.
Monel 400 Khoom
Zoo heev corrosion:
Dej hiav txwv thiab cov tubrog nkoj: zoo super tsis kam rau Sevwater, brine, thiab kev ntxhov siab tsis muaj zog ntawm ntau yam kev ua haujlwm ntawm chloride hauv chloride -}} kev nplua nuj ib puag ncig.
Acids: kev ua tau zoo heev tiv thaiv sulfuric acid (tshwj xeeb yog aerated), hydrofluoric acid (HF), phosphoric acid, thiab ntau cov organic acids. Kev tawm tsam nrog nce cov ntsiab lus nickel ntau.

Cov Lus Nug
Q: Dab tsi yog qhov txawv ntawm Monel 400 thiab inconel?
A: Inconel alloys (zoo li 600, 625, 718) yog li cas}}} oi ecidizing corrosive ib puag ncig. Monel 400 yog nickel - tooj liab raws, txo cov kua qaub, hf), thiab tiv taus chloride scc. Lawv muab cov hom phiaj sib txawv.
Q: Dab tsi kub yuav muaj monel 400 walland?
A: Nws khaws lub zog muaj txiaj ntsig txog li 540℃(1000℃f). Rau lub siab siab - kub o} kev kawm qib siab tshaj li 600℃(1110℃f),} tiv taus almoys zoo li inconel 600 yog nyiam.
Q: Monel 400 sib nqus?
A: Monel 400 feem ntau yog tsis-}} sib nqus hauv kev ua haujlwm tsis muaj tseeb. Mob khaub thuas ua haujlwm puas tuaj yeem tsis muaj kev sib nqus me me sib nqus permeability.
Q: Kuv yuav ua li cas weld monel 400?
A: Siv cov hlau ua tub rog tso quav (piv txwv li, ornicu - 7 / monel 60 rau tus nplaig / mig, enicu-7 rau lo). Ua haujlwm kom zoo tu (tshem tawm cov oxides, roj, roj) thiab cov tswv yim kom tsis txhob kub tawg (muaj kev cuam tshuam ntau dua). Tom qab Weld tu yog qhov tseem ceeb heev.
