(Nickel 702) Strip, Coil, Foil & Wire, AMS 5550

Applications 

lnconel® 702 (Alloy 702) is used in afterburner liners, furnace components. 

Description 

lnconel® 702 (Alloy 702) is a nickel-chromium alloy with an aluminum addition that makes this grade high resistant to oxidation at temperatures up to 2400 °F (1316 °C). The alloy has good strength at high temperatures. Age hardening improves the strength up to 1500 °F (816 °C).

Additional Properties

Corrosion Resistance

Refer to NACE (National Associate of Corrosion Engineers) for recommendations. 

Finishes

#1 - Hot rolled annealed and descaled. It is available in strip, foil and ribbon. It is used for applications where a smooth decorative finish is not required.  
#2D - Dull finish produced by cold rolling, annealing and descaling. Used for deep drawn parts and those parts that need to retain lubricants in the forming process.  #2B - Smooth finish produced by cold rolling, annealing and descaling. A light cold rolling pass is added after anneal with polished rolls giving it a brighter finish than 2D. 
#BA - Bright annealed cold rolled and bright annealed 
#CBA - Course bright annealed cold rolled matte finish and bright anneal 
#2 - Cold Rolled  #2BA- Smooth finish produced by cold rolling and bright annealing. A light pass using highly polished rolls produces a glossy finish. A 2BA finish may be used for lightly formed applications where a glossy finish is desired in the formed part.  Polished - Various grit finish for specific polish finished requirements. 
* Not all finishes are available in all alloys - Consult Sales for applicable finishes.

Wire Finishes

XC - Extra Clean Bright Annealed or Bright Annealed and Cold Rolled Grease - Ultra bright finish (for decorative applications)  Soap - Soap coating on tempered wire to act as lubricant.  * Contact Ulbrich Wire with special finish requests.

Heat Treatment

lnconel® 702 (Alloy 702) can be hardened by cold working and by a heat treatment.
