Njirimara Alloy20
Alloy N08020 bụ nickel-iron-chromium austenitic alloy nwere ọmarịcha nguzogide acid ọgụ, pitting na crevice corrosion yana acids na kemịkalụ nwere chloride, corrosion izugbe na corrosion intergranular.Alloy na-ejikọta ezigbo nguzogide corrosion, ịdị mfe nke imepụta ihe na ihe eji arụ ọrụ emeziwanye.
Alloy N08020 bụkwa nke a na-akpọ Carpenter 20, Incoloy na 20Cb-3.
N08020 bụ niobium kwadoro obere carbon austenitic nickel-iron-chromium alloy nwere ọla kọpa na molybdenum.
