Alloy 242 is a nickel-molybdenum-chromium age hardenable alloy which derives strength from a log-range ordering reaction upon aging. It has tensile and creep strength properties up to 1300°F which are as much as double for solid solution strengthened alloys, but with high ductility in the aged condition. The thermal expansion characteristics of alloy 242 are much lower than those for most other alloys, and it has very good oxidation resistance up to 1500°F.

Alloy 242 can be cold rolled to achieve the temper properties required by specific customers and/or manufacturing requirements. Contact Ulbrich Wire for details.
Refer to NACE (National Association of Corrosion Engineers) for recommendations
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.
