Monel 400 (UNS N04400/2.4360) wani ƙarfe ne na nickel-copper wanda ke da ƙarfi mai yawa kuma yana da kyakkyawan juriya ga nau'ikan abubuwan da ke haifar da ruwa, gami da ruwan teku, acid mai narkewar hydrofluoric da sulfuric, da alkali.
Monel 400 wanda ke ɗauke da kusan kashi 30-33% na jan ƙarfe a cikin matrix na nickel yana da halaye iri ɗaya da yawa na nickel mai tsabta a cikin kasuwanci, yayin da yake ingantawa akan wasu da yawa. Ƙara wasu baƙin ƙarfe yana inganta juriya ga cavitation da zaizayar ƙasa a cikin aikace-aikacen bututun mai. Babban amfani da Monel 400 yana ƙarƙashin yanayi mai saurin kwarara da zaizayar ƙasa kamar a cikin shafts na propeller, propellers, ruwan famfo-impeller, casings, bututun mai condenser, da bututun mai musayar zafi. Yawan tsatsa a cikin ruwan teku mai motsi gabaɗaya ƙasa da 0.025 mm/shekara. Haɗin zai iya shiga cikin ruwan teku mai tsayawa, duk da haka, ƙimar hari ya yi ƙasa da na ƙarfe mai tsabta a cikin kasuwanci 200. Saboda yawan sinadarin nickel (kimanin 65%), ƙarfe gabaɗaya ba shi da kariya daga tsatsawar chloride. Juriyar tsatsa ta Monel 400 a cikin acid na ma'adinai marasa oxidative ya fi kyau idan aka kwatanta da nickel. Duk da haka, yana fama da irin wannan rauni na nuna ƙarancin juriya ga tsatsa ga hanyoyin iskar oxygen kamar ferric chloride, cupric chloride, wet chlorine, chromic acid, sulfur dioxide, ko ammonia. A cikin maganin hydrochloric da sulfuric acid wanda ba a tace ba, ƙarfen yana da juriya mai amfani har zuwa yawan 15% a zafin ɗaki da kuma har zuwa 2% a ɗan zafin jiki mafi girma, wanda bai wuce 50°C ba. Saboda wannan takamaiman halayyar, ana amfani da Monel 400 da NiWire ke samarwa a cikin hanyoyin da sinadarai masu chlorine za su iya samar da hydrochloric acid saboda hydrolysis, wanda zai haifar da gazawa a cikin ƙarfe na yau da kullun.
Monel 400 yana da kyakkyawan juriya ga tsatsa a yanayin zafi na yanayi ga duk wani taro na HF idan babu iska. Maganin iska da zafin jiki mai yawa suna ƙara yawan tsatsa. Haɗin yana da sauƙin kamuwa da tsatsa a cikin tururin hydrofluoric ko hydrofluorosilic acid mai danshi. Ana iya rage wannan ta hanyar rage yanayin muhalli ko kuma rage damuwa a cikin abin da ake magana a kai.
Amfani da aka saba yi sune sassan bawul da famfo, shafts na propeller, kayan haɗin ruwa da mannewa, kayan lantarki, kayan aikin sarrafa sinadarai, tankunan mai da ruwan sha, kayan aikin sarrafa mai, na'urorin dumama ruwan dafa abinci da sauran masu musayar zafi.
