Monel 400 (tsis muaj N04400) yog npib tsib xee- tooj liab alloy muaj qhov ua tau zoo dua, thiab kev ua tau zoo heev hauv cov kev ua tau zoo. Ameslikas tau tsim los ntawm cov tuam txhab tsib xee thoob ntiaj teb (Inco), cov tshuaj no tau dhau los ua nws cov khoom siv dej hiav txwv, acids, thiab siab {4} kev siv kub.
Qhov blog tshawb tau cov khoom siv, tshuaj lom neeg, cov yam ntxwv neeg kho tshuab, thiab kev siv khoom siv tsis tau N04400.

Monel 400 yog cov khoom -} tov alloy nrog qhov sib npaug sib npaug ntawm Nickel thiab tooj liab. Nws cov ntawv cim raug suav nrog:
Nickel (NI): 63-70% (muab cov neeg tau txais kev txhim kho corrosion tsis ruaj khov thiab ruaj khov).
Tooj liab (CU): 28-34% (txhim kho kom tsis txhob txo cov xov xwm thiab sulfuric acid).
Hlau (FE): tsawg dua lossis sib npaug ntawm 2.5% (txhim kho lub zog thiab oxidation tsis kam).
Manganese (MN): Tsawg dua lossis sib luag rau 2.0% thiab silicon (Si): tsawg dua lossis sib npaug nrog 0.5% (pub khoom lag luam).
Cov pa roj carbon (c): tsawg dua los yog sib npaug rau 0.3% thiab Sulphur (s): tsawg dua lossis sib luag rau 0.024% (txo qhov kev cuam tshuam).

Monel 400 paub txuj ci hauv ob qho tib si txo thiab oxidizing ib puag ncig, nrog kev ua tau zoo hauv:
Dej hiav txwv thiab cov dej brackish: tsis kam rau yaig, cavitation, thiab chloride - induced corrosion.
Acids thiab tshuaj lom neeg:
Withstands hydrofluoric acid (txhua qhov ntau, suav nrog deagerated cov ntaub ntawv) thiab sulfuric acid.
Tsis kam ua alkalis, ntsev, thiab cov organic sib txuas tab sis muaj cov kua qaub oxidizing.
Kev siv cov ntaub ntawv: siv nyob rau hauv cov twj, li qub, kev sib pauv cua sov, thiab cov tub rog ua kom sov vim yog cov qauv hauv acidos thiab kua qaub.
