ASTM B163 Monel400 yog qhov khoom siv tiv thaiv corrosion nrog ntau tshaj plaws, qhov ntau tshaj thiab zoo tshaj plaws kev coj ua. Cov alloy muaj zoo tshaj plaws corrosion tsis kam nyob rau hauv hydrofluoric acid thiab fluorine roj media, thiab zoo heev corrosion tsis kam mus rau kub concentrated alkali cawv. Nws kuj tseem tiv taus xeb los ntawm kev daws teeb meem, dej, dej hiav txwv, cua, organic sib txuas, thiab lwm yam. Qhov tseem ceeb ntawm cov hlau no yog tias kev xeb corrosion tawg feem ntau tsis tsim thiab kev txiav ua tiav zoo.
Tshuaj lom neeg muaj pes tsawg leeg ntawm Monel400 alloy yog tsim nrog 30% Cu thiab 65% Ni ntxiv rau me me ntawm Fe (1% -2%). Vim tias qhov sib txawv ntawm cov tshuaj lom neeg muaj pes tsawg leeg, nws tuaj yeem muaj ntau qib qib hlau, tab sis tsis muaj qhov sib txawv ntawm kev txhim kho corrosion ntawm lawv. Monel400 alloy ntau tiv taus xeb los ntawm kev txo cov xov xwm dua li cov ntshiab nickel, thiab muaj kev tiv thaiv ntau dua los ntawm xeb los ntawm oxidizing media tshaj li tooj liab ntshiab.

Monel-400 alloy hlau
Cov tshuaj lom neeg lub cev muaj pes tsawg leeg ntawm Monel400 alloy: C: ≤0.3, Si: ≤0.50, Mn: ≤2.0, Ni: ≥63, Cu: 28 ～ 34, S: ≤ 0.024, Fe ≤ 2.5, Chav:%
Tshuaj lom neeg muaj pes tsawg leeg ntawm Monel400 alloy muaj xws li 30% Cu thiab 65% Ni ntxiv rau me me ntawm Fe (1% - 2%). Cov qauv ntaub so ntswg yog qhov ua haujlwm ib-theem austenite tus qauv. Txij li cov npib tsib xee thiab tooj liab yog ob leeg ua ke nyob rau hauv ib qho kev sib piv, feem ntau tsis muaj intermetallic theem nag lossis daus. Kev soj ntsuam lub microstructure ntawm cov alloy nyob rau hauv qhov uas tsis yog nyob hauv qab lub tshuab tsom, nws tuaj yeem pom tias muaj qhov sib txawv tsis yog xim hlau rau ntawm qhov austenite matrix, xws li sulfides thiab silicates. Hauv qee qhov xwm txheej, qhov pom ntawm carbides kuj tau pom.
