Inconel 925 Sheets & Plates

What are Inconel 925 Sheets & Plates?

Inconel 925 (UNS N09925) is a nickel-iron-chromium alloy strengthened by precipitation hardening with additions of molybdenum, copper, titanium, and aluminum. It offers a combination of high strength and excellent corrosion resistance, particularly in sour gas and oilfield environments.

• Provide high strength and durability
• Resist corrosion in aggressive environments
• Perform efficiently under high pressure and stress
• Ensure long-term reliability in oil & gas applications

Chemical Composition of Inconel 925

Typical Composition:

• Nickel (Ni): 42% – 46%
• Chromium (Cr): 19.5% – 23.5%
• Iron (Fe): Balance
• Molybdenum (Mo): 2.5% – 3.5%
• Copper (Cu): 1.5% – 3.0%
• Titanium (Ti): 1.9% – 2.4%
• Aluminum (Al): 0.1% – 0.5%

This composition enhances strength through precipitation hardening and improves corrosion resistance in harsh environments.
