Ego 400(UNS N04400 / 2.4360) bụ ihe nickel-ọla kọpa nwere ike dị elu na nguzogide dị mma maka ọtụtụ mgbasa ozi gụnyere mmiri mmiri, dilute hydrofluoric na sulfuric acid, na alkalies.
Monel 400 nwere ihe dị ka 30-33% ọla kọpa na matriks nickel nwere ọtụtụ njirimara yiri nke nickel dị ọcha nke azụmahịa, ebe ọ na-akawanye mma n'ọtụtụ ndị ọzọ. Mgbakwunye nke ụfọdụ ígwè na-eme ka iguzogide cavitation na mbuze na ngwa tube condenser na-eme ka mma. Isi ojiji nke Monel 400 nọ n'okpuru ọnọdụ nke oke ọsọ ọsọ na mbuze dị ka n'osisi propeller, propellers, pulp-impeller blades, casings, condenser tubes, and heat exchanger tubes. Ọnụego corrosion na mmiri oké osimiri na-akpụ akpụ na-adịkarị ala karịa 0.025 mm / afọ. Alloy nwere ike ịbanye n'ime mmiri mmiri na-adịghị ahụkebe, Otú ọ dị, ọ̀tụ̀tụ̀ ọgụ a na-awakpo dị nnọọ nta karịa nke dị ọcha alloy 200 nke azụmahịa. N'ihi nnukwu ọdịnaya nickel ya (ihe dị ka 65%), alloy na-abụkarị nke na-adịghị egbochi chloride stress corrosion cracking. Nguzogide corrosion n'ozuzu nke Monel 400 n'ime acid mineral nonoxidizing ka mma ma e jiri ya tụnyere nickel. Otú ọ dị, ọ na-enwe otu adịghị ike nke igosipụta nguzogide corrosion na-adịghị mma maka mgbasa ozi oxidizing dị ka ferric chloride, cupric chloride, chlorine mmiri, chromic acid, sulfur dioxide, ma ọ bụ amonia. Na ngwọta hydrochloric na sulfuric acid na-enweghị mgbaze, alloy nwere nguzogide bara uru ruo 15% n'ime ụlọ okpomọkụ yana ruo 2% na obere okpomọkụ dị elu, ọ bụghị ihe karịrị 50 ° C. N'ihi njirimara a kapịrị ọnụ, a na-ejikwa Monel 400 nke NiWire mepụtara na usoro ebe ihe mgbaze chlorinated nwere ike ịmalite hydrochloric acid n'ihi hydrolysis, nke ga-eme ka ọdịda na igwe anaghị agba nchara.
Monel 400 nwere ezigbo nguzogide corrosion na ọnọdụ okpomọkụ na ntinye HF niile na enweghị ikuku. Ngwọta ikuku na okpomọkụ dị elu na-abawanye ọnụego corrosion. Alloy ahụ nwere ike ịdaba na corrosion nrụgide na-agbawa na mmiri ikuku hydrofluoric ma ọ bụ hydrofluorosilic acid vapor. Enwere ike ibelata nke a site n'ibelata gburugburu ebe obibi ma ọ bụ site na mgbakasị ahụ na-ebelata ike nke akụrụngwa a na-ekwu.
Ngwa ndị a na-ahụkarị bụ valvụ na akụkụ mgbapụta, ihe mkpuchi ụgbọ mmiri, ihe ndozi mmiri na ihe ngbochi, ihe elektrọnik, akụrụngwa na-edozi kemịkalụ, mmanụ ụgbọ ala na tankị mmiri ọhụrụ, akụrụngwa na-edozi mmanụ ala, igwe na-ekpo ọkụ mmiri na-ekpo ọkụ na ihe ndị ọzọ na-agbanwe ọkụ.
