Description
AL-6XN® is low carbon, nitrogen bearing super austenitic stainless steel. The alloy was designed to be a seawater resistant material and has been found to be resistant to a broad range of corrosive environments. Due to the alloy's corrosion resistance and high strength, AL-6XN® is a better choice than conventional duplex stainless alloy and more cost effective nickel-base alloys.

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 for 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 is not removed from tempered wire to act as a lubricant. * Contact Ulbrich Wire with special finish requests.

Heat Treatment
AL-6XN® is non hardenable by heat treatment.
