L-605 Alloy Description or Haynes® 25 Wire Description


L-605 is a cobalt based alloy resistant to oxidation and carburization to 1900°F and has good forming and excellent high temperature properties. Alloy L-605 can only be hardened significantly by cold working. Cold working will increase creep strength up to 1800°F and stress rupture strength up to 1500°F. Strain aging at 700-1100°F improve creep and stress rupture strengths below 1300°F.

Applications


Seal rings for gas turbines
Jet engine components
High temperature ball bearings and races
Springs

Properties Tempered


Alloy L-605 can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.

Additional Properties


Corrosion Resistance


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
