Additional Properties

Corrosion Resistance

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


# 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 for all alloys - Contact Ulbrich Sales for more information.

Wire Finishes

XC - Extra clean bright annealed or bright annealed and cold rolled Grease - Ultra-bright finish (for decorative applications)  Soap - Soap is not removed from tempered wire to act as a lubricant. 

* Contact Ulbrich Wire for custom wire finishes.

Cold Forming

Type 444 provides excellent formability and can be readily deep drawn and spin formed. Stretch forming, however, is limited in application for this alloy. 

Heat Treatment

Type 444 is non-heat treatable.
