Incoloy alloy 925UNS N09925) na mgbakwunye nke molybdenum, ọla kọpa, titanium, na aluminom bụ afọ nickel-iron-chromium alloy siri ike, na-enye ngwakọta nke ike dị elu na nguzogide corrosion dị mma. Ọdịnaya nickel zuru oke na-enye nchebe pụọ na mgbawa chloride-ion stress-corrosion ebe yana njikọ molybdenum na ọla kọpa agbakwunyere, a na-enwe mmasị iguzogide ibelata kemịkalụ. Molybdenum na-enye aka n'iguzogide pitting na crevice corrosion, ebe chromium na-enye iguzogide gburugburu oxidizing. N'oge ọgwụgwọ okpomọkụ, mmeghachi omume na-ewusi ike na-akpata site na mgbakwunye nke titanium na aluminom.

Ngwa na-achọ nchikota nke ike dị elu na nguzogide corrosion nwere ike ịtụle Incoloy alloy 925. Nguzogide sulfide stress cracking na nrụgide-corrosion cracking na "utoojoo" mmanụ crude na eke gas gburugburu pụtara na ọ na-eji maka ala-oghere na n'elu gas-nke ọma components nakwa dị ka ịchọta ojiji na mmiri na mgbapụta ogwe ma ọ bụ elu-ike usoro piping.
