Incoloy alloy 925 (UNS N09925) Site na mgbakwunye nke molybdenum, ọla kọpa, titanium, na aluminom bụ ihe mgbakwunye nickel-iron-chromium nke a na-eme ka ọ sie ike ruo ogologo oge, na-enye njikọta nke ike dị elu na ezigbo iguzogide nchara. Ngụkọta nickel zuru oke na-enye nchebe megide mgbawa nrụgide chloride-ion-corrosion ebe ọ bụ na conjuncton na molybdenum na ọla kọpa agbakwunyere, a na-enweta iguzogide kemịkalụ na-ebelata. Molybdenum na-enyekwa aka na iguzogide pitting na corrosion crevice, ebe chromium na-enye iguzogide gburugburu oxidizing. N'oge ọgwụgwọ okpomọkụ, mmeghachi omume na-eme ka ọ sie ike site na mgbakwunye nke titanium na aluminom.

Ngwa ndị chọrọ njikọta nke ike dị elu na iguzogide nchara nwere ike ịtụle alloy Incoloy 925. Nguzogide nke mgbawa nrụgide sulfide na mgbawa nrụgide-njehie na gburugburu mmanụ ala na gas eke pụtara na ejiri ya maka akụkụ olulu gas dị n'okpuru ala na n'elu yana ịchọta ojiji na ogwe mmiri na ọkpọ mmiri ma ọ bụ sistemụ ọkpọkọ siri ike.
