N08825/Incoloy Alloy 825/NS142/NiCr21Mo/2.4858/NCF 825 Incoloy Alloy Bar For Power Generation

Incoloy 825 (N08825, 2.4858, NiCr21Mo) is a nickel-iron-chromium alloy with added molybdenum, copper, and titanium, offering excellent corrosion resistance in harsh environments. It is highly resistant to oxidizing and reducing acids, pitting, crevice corrosion, and stress corrosion cracking. Commonly used in chemical processing, marine, and nuclear industries, Incoloy 825 maintains strength and stability in extreme temperatures up to 540°C (1000°F). It is also weldable and easy to fabricate. The alloy’s high nickel content ensures resistance to chloride-induced stress corrosion cracking, while molybdenum enhances its protection against localized corrosion. Available in bars, rods, and other forms, Incoloy 825 is widely used in heat exchangers, piping, and marine applications requiring superior corrosion resistance.
