Incoloy 25-6MO with World Wide
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
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.
