Incoloy 926

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. The alloy is especially resistant to non-oxidizing acids such as sulfuric and phosphoric. The high molybdenum content and nitrogen provide resistance to pitting and crevice corrosion, while copper enhances resistance to sulfuric acid.

The most notable property of Incoloy 926 is its excellent corrosion resistance. It performs well in a variety of corrosive environments, including those containing chlorides, sulfides, acids, alkalis, and salts. In addition, it is resistant to various forms of corrosion such as pitting, crevice corrosion, stress corrosion cracking, and intergranular corrosion.

In addition to excellent corrosion resistance, Incoloy 926 also has good mechanical properties. It has high strength, good ductility, and toughness, and can maintain stable mechanical properties in high and low-temperature environments.

The weldability of Incoloy 926 is also excellent. It can be welded by a variety of welding methods, including gas tungsten arc welding, gas metal arc welding, and resistance welding. The welded joint has good corrosion resistance and mechanical properties.

Incoloy 926 also has good processing properties, wear resistance, and fatigue resistance. At the same time, its thermal stability is also very good, and it can work in high-temperature environments for a long time without obvious performance degradation.
