Designatur ut UNS N08825 vel DIN W.Nr. 2.4858, Incoloy 825 (etiam "Alloy 825" appellatum est chromium ferreum-nickel-alaymus cum additionibus molybdeni, cooperi et titanii. Molybdenum ad- hibitionem suam resistit ad fovendum corrosionem in applicatione aquei corrosionis, dum aes contentum resistit acido sulphurico. Titanium ad stabilizationem accedit. Alloy 825 optimum resistentiam habet ad acida reducenda et oxydizantia, ad corrosionem rimas accentus, et ad oppugnationem localem sicut fovere et corrosio rima. Maxime repugnant acida sulphurica et phosphorica. Incoloy 825 mixtura maxime adhibetur ad processui chemici, fistulae petrochemicae, apparatum pollutionis, olei et gasi bene limbis, cibus nuclei reprocessio, productio acido et instrumento servantur.
