Haynes® 282 and Alloy 282 Wire Description

Alloy 282 is a corrosion and heat resistant gamma-prime strengthened nickel base alloy. Used in applications requiring high strength up to 1600°F (982°C) but not limited to those alone. The alloy has excellent creep strength in the temperature range of 1200-1700°F (649-927°C), surpassing Waspaloy® and approaching R-41.

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

Continuous Coils
Cut to lengths
Precision cutting

Heat Treatment

Alloy 282 is hardenable by cold working and by heat treatment.
