Njengoba kulindelekile kokuqukethwe kwayo kwethusi okuphezulu, ingxubevange engu-400 ihlaselwa ngokushesha yi-nitric acid nezinhlelo ze-ammonia.
I-Monel 400 inezakhiwo ezinhle zemishini emazingeni okushisa angaphansi kwezinga-qhwa, ingasetshenziswa emazingeni okushisa afinyelela ku-1000° F, futhi indawo yayo yokuncibilika iwu-2370-2460° F. Nokho, ingxubevange engu-400 inamandla aphansi esimweni sokuthukuthela ngakho, ukufutheka okuhlukahlukene ingasetshenziswa ukwandisa amandla.
