Hobaneng ha Monel 400 e Sebetsa (le moo e sa sebetseng)
Monel 400 ke 67% nickel, 30% koporo, e nang le trace iron le manganese. Sebopeho seo se fana ka mekhoa e 'meli e ke keng ea buisanoa: ho itšireletsa ho sekoti se bakoang ke chloride le botsitso ho pholletsa le pH 2-12. Ha e le hantle, sena se bolela hore ntlo ea pompo ea piston setsing sa desalination e nka 3.2 × nako e telele ho feta 316 tšepe e sa hloekang - e tiisitsoe ke lintlha tsa rona tsa tšimo ea likhoeli tse 18 ho tloha lits'ebetsong tse tharo tsa North Sea. Empa Monel 400 e hloleha ka potlako tlas'a khatello ea maikutlo e tsitsitseng ka holimo ho 450 MPa kapa ha e pepesehetse ho chesa, e tsitsitseng ea sulfuric acid. Re kile ra lahla li-valve tse 47 ka mor'a hore li pshatlehe nakong ea tlhahlobo ea metsi - hobane moreki o ile a bolela Monel 400 bakeng sa mohala oa litšebeletso oa 500 ° C H₂SO₄.
