Inconel 625 Alloy Wire Description


Inconel 625 is a non-magnetic, corrosion and oxidation resistant, nickel-chromium alloy. This material can be used because of its high strength, excellent uniform corrosion resistance, resistance to stress cracking and excellent pitting resistance in 500°-600°F (260-316°C) water. Its outstanding strength and toughness in the temperature range from cryogenic to 2000°F (1093°C) are derived primarily from the solid solution effects of the refractory metals columbium and molybdenum in a nickel-chromium matrix. The alloy has excellent fatigue strength and stress corrosion cracking to chloride ions.

Additional Properties of Inconel 625


Inconel is a Corrosion Resistant Alloy


Refer to NACE (National Association of Corrosion Engineers) for recommendations

Standard Wire Finishes


Extra Clean: (XC) Extra clean is also referred to as “bright annealed” or “bright annealed and cold rolled”

Grease (round wire only): Drawn in a heavy grease produces an “Ultra bright” finish for decorative applications

Soap (round wire only): Soap is used as a lubricant in the drawing process and is not removed. It acts as a lubricant during customer part forming operation.

A soap finish is available in tempered products.
Plated: Many plating options are available.
*Special finishes are available: Contact Ulbrich Wire Sales with special finish and plating requests.

Forms


Continuous Coils
Cut to lengths
Precision cutting

Heat Treatment


Alloy625 cannot be hardened heat treating
