Additional Properties

Corrosion Resistance of Ti 15-3-3-3

Refer to NACE (National Associate 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 in all alloys - Contact Ulbrich Sales for more information.
