What is bright annealed finish?
A bright annealed finish is produced by heat-treating (annealing) in a controlled atmosphere furnace. It has a bright, reflective appearance, but may have some cloudiness and other imperfections.
What is bright finish on stainless steel?
A bright, cold-rolled finish is the most commonly “Mill” finish for light gauge stainless steel sheet. It resembles a very hazy mirror, with some reflection evident. It is obtained by a final light roll pass of the sheet through polished rolls.
What does 2B mean in stainless steel?
smooth, moderately reflective cold-rolled
2B is the term used by the ASTM A480 standard to define “a smooth, moderately reflective cold-rolled annealed and pickled or descaled finish typically produced by imparting a final light cold-rolled pass using polished rolls.” It is the most widely-used stainless steel finish available today.

What is 1b finish stainless steel?
No. 1 Finish is produced by rolling stainless steel that has been heated prior to rolling (hot-rolling). This is followed by a heat treatment that produces a uniform microstructure (annealing) and ensures that the stainless steel will meet mechanical property requirements.
What is No 6 finish on stainless steel?
The No. 6 Fine Satin Finish delivers a “2B mill-finish-surface-roughness-equivalent” with a fine-grain satin appearance. It has a higher degree of surface lubricity and reflectivity than our No. 4 Standard Satin Finish (32 Ra max), aiding cleanability and bacteria-free surfaces.
How do you get a 3 finish on stainless steel?
Stainless Steel Finish #3 (Brushed) An intermediate polished surface obtained by finishing with a 120-grit abrasive. A directional course “grain” running in one direction.
What is annealed 2B stainless steel?
2B – A smooth, moderately reflective cold-rolled annealed and pickled or descaled finish typically produced by imparting a final light cold-rolled pass using [large diameter] polished rolls. This general-purpose finish is more readily polished than No 1 or 2D finishes.
