What Is 2B Finish Stainless Steel?
The 2B finish is one of the most commonly used cold-rolled stainless steel finishes. After cold rolling, the material is annealed, pickled, and lightly skin-pass rolled to produce a smooth and uniform matte appearance.
Advantages of 2B Finish
Excellent flatness
Uniform appearance
Easy cleaning
Good corrosion resistance
Ideal base for polishing
Cost-effective industrial finish
