Incoloy 925 Alloy Steel Bar

 

INCOLOY® alloy 925 (UNS N09925) is an agehardenable INCOLOY® alloy 925 (UNS N09925) is an agehardenablenickel-iron-chromium alloy with additionsof molybdenum, copper, titanium and aluminum. The alloy’ isdesigned to provide a combination of high strength andexcellent corrosion resistance. The nickel content issufficient for protection against chloride-ion stresscorrosioncracking. The nickel, in conjunction with themolybdenum and copper, also gives outstandingresistance to reducing chemicals. The molybdenum aidsresistance to pitting and crevice corrosion. The alloy’schromium content provides resistance to oxidizingenvironments. The titanium and aluminum additionscause a strengthening reaction during heat treatment.


INCOLOY alloy 925 is used in variousapplications requiring a combination of high strengthand corrosion resistance. Because of the alloy’sresistance to sulfide stress cracking and stress-corrosioncracking in “sour” (H2S containing) crude oil andnatural gas, it is used for down-hole and surface gaswellcomponents including tubular products, valves,hangers, landing nipples, tool joints and packers. Thealloy is also useful for fasteners, marine and pumpshafting and high-strength piping systems.

 

Application:

 

  • Protection in oxidizing and reducing atmosphere
  • Resistance to chloride ion stress-corrosion cracking
  • Excellent resistance to pitting and crevice corrosion
  • Many different industries rely on Alloy 925 for a number of uses including:
  • Valves, hangers, packers, and tubulars for sour gas production
  • Marine fasteners and pump shafts

 

Inconel® 925 Chemical Composition:
