Incoloy 25-6Mo

Incoloy 25-6Mo

INCOLOY 25-6MO alloy is an iron-based super-austenitic stainless steel with elevated resistance to a variety of corrosive surroundings. Its alloying elements of molybdenum and nitrogen offer protection from pitting/crevice corrosion, and copper presents protection from sulfuric acid. INCOLOY 25-6MO boasts improved properties in comparison to 316 stainless steel, yet remains a cost-efficient alternate to other nickel-based alloys.

Incoloy 25-6Mo

Essential details
INCOLOY alloys belong to the category of super-austenitic stainless steel alloys. Nickel, chromium and iron are the principal constituents of this alloy. By adding different additives this alloy can be made to resist different chemical reagents. Good strength and resistance to corrosion are characteristics of these alloys.

Additives such as molybdenum and nitrogen are added to the alloy in order to increase its resistance to pitting, crevice corrosion and thermal stability. The nickel and chromium content extend the corrosion resistance of this alloy over a wide range of environments like non-oxidizing acids, aqueous, caustic chlorides, halides and pulp-mill bleaches. This alloy is available in the form of bars, billets, sheets, round, plate, strips and wire.
