Incoloy 25-6MO with World Wide Shipping

INCOLOY® alloy 25-6MO (also known under UNS N08926/W. Nr. 1.4529, formerly UNS N08925) is a super-austenitic stainless steel consisting of 6% molybdenum and enhanced by an addition of nitrogen. The nickel and chromium make-up of this alloy make it resistant to a wide range of corrosive conditions.


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.

Lightning Bolt offers a wide range of hard to find anti-corrosive alloy fasteners. Such alloys include INCOLOY alloy 25-6MO which is a fully austenitic alloy containing 6% molybdenum and offering excellent corrosion resistance in a wide variety of aggressive, aqueous environments. This alloy can be made into many types of fasteners including nuts, bolts, hex cap screws, studs and washers.


This alloy replaces the conventional, austenitic stainless steels (AISI 316 and 317), where their capabilities are pushed to their performance limits. The alloy, therefore, falls into a “super austenitic stainless steel” category. It has been known to represent a cost-effective alternative to the higher nickel alloys in some marine and chemical processing environments. One of the outstanding characteristics of INCOLOY alloy 25-6MO is its resistance to environments containing chlorides or other halides.


This alloy is especially capable of handling high-chloride environments such as brackish water, sea water, caustic chlorides and pulp mill bleach systems. Common applications include chemical and food processing, pulp and paper bleaching plants, marine and offshore platform equipment, salt plant evaporators, air pollution control systems, and condenser tubing, service water piping, and feedwater heaters for the power industry.

When the task calls for hard to find alloy fasteners such as Incoloy alloy 25-6MO, call Lightning Bolt. We have years of experience in anti-corrosive fasteners, and can help you meet the fastening demands of your unique project.
