Incoloy 926 Stainless Steel Flange AISI 926 nickel alloy flange

Molybdenum and nitrogen content significantly increased the resistance of pitting and crevice corrosion in the halide media. Meantime, nickel and nitrogen not only ensures the stability of metallographical, but also reduce separating intergranular trend in the thermal process or welding process better than the nitrogen content of nickel alloy.

Incoloy 926 Stainless Steel Flange containing 14.0-18.0% Cr and 24.0-26.0% Ni. It is a nickel-based alloy containing titanium and aluminum with enough chromium to form and maintain a sufficient scale of chromium oxide to protect it in high temperature conditions. Incoloy 926 is more heat resistant than typical chrome-nickel stainless steels such as 304. The high nickel content makes it more resistant to oxidation than standard 18-8 stainless steel. The alloy is particularly resistant to non-oxidizing acids such as sulfuric and phosphoric acids. High molybdenum content and nitrogen provide resistance to pitting and crevice corrosion, while copper increases resistance to sulfuric acid. INCOLOY alloy 926 is a 6% molybdenum fully austenitic alloy that provides excellent corrosion resistance in a variety of corrosive, aqueous environments. INCOLOY alloy 926 (UNS N08926 / W. Nr. 1.4529 / INCOLOY? alloy 25-6MO) is a super-austenitic stainless steel containing 6% molybdenum and enhanced by an addition of nitrogen. The nickel and chromium contents of this alloy make it resistant to a wide range of corrosive environments.
