High-Strength Incoloy 925 Rod for Corrosive Environments
Incoloy 925 (UNS N09925) is a precipitation-hardenable nickel-iron-chromium alloy enriched with molybdenum, copper, titanium, and aluminum. This unique composition endows it with exceptional strength and outstanding resistance to a wide range of corrosive environments, including those containing sulfuric and phosphoric acids, seawater, and other chloride-rich media. Its high nickel content offers protection against chloride-ion stress-corrosion cracking, while the combination of molybdenum and copper provides resistance to reducing chemicals. The alloy's chromium content ensures resistance to oxidizing environments, making it ideal for applications in chemical processing, marine engineering, and oil and gas industries.
