Strip, Coil, Foil and Wire, ASTM B333

Applications

Hastelloy® B-2 is used for most chemical process applications in the welded condition, gasoline refining.

Description

Hastelloy® 8-2 is a nickel-base wrought alloy with excellent resistance to hydrochloric acid at all concentrations and temperatures. Therefore, it has great resistance to stress-corrosion cracking and pitting. It also withstands hydrogen chloride, sulfuric, acetic and phosphoric acids.

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 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 coating on tempered wire to act as lubricant.

* Contact Wire with special finish requests.

Heat Treatment

Hastelloy® B-2 is non hardenable by heat treatment.
