company news about ASTM B564 Incoloy 825 Forging Ring | UNS N08825 Ring Manufacturer & Supplier

ASTM B564 Incoloy 825 forging rings are high-performance nickel alloy forging rings designed for excellent corrosion resistance in aggressive environments. Known as UNS N08825 forging rings, this alloy combines nickel, iron, and chromium with molybdenum, copper, and titanium to deliver superior resistance to both oxidizing and reducing acids.

As a reliable solution for critical industries, Incoloy 825 forged rings are widely used in oil & gas, chemical processing, and marine applications.

Chemical Composition of Incoloy 825 (UNS N08825)

Incoloy 825 is engineered for durability and corrosion resistance:

• Nickel (Ni): 38.0–46.0%
• Chromium (Cr): 19.5–23.5%
• Iron (Fe): ≥22.0%
• Molybdenum (Mo): 2.5–3.5%
• Copper (Cu): 1.5–3.0%
• Titanium (Ti): 0.6–1.2%

This composition enhances resistance to pitting corrosion, crevice corrosion, and stress corrosion cracking, making it ideal for corrosion-resistant forging rings.

Key Properties of ASTM B564 Incoloy 825 Forging Rings
