What is a 2B surface finish?

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 a 2H finish?

2H Finish – Cold Rolled & Work Hardened This one is a little different from the rest of the mill finishes. Here, the metal is cold worked after the cold rolling process in order to obtain improved strength. The hardening is done by means of temper rolling on polished rolls.

What are the different finishes of steel?

Types of metal finishes. Metal finishing involves treating the exterior of a metal product or component with a thin layer of augmenting material or removing material from the component’s surface.

  • What is the difference between 2B and 2D finish?

    2B and the 2D surface is that No 2B have a smooth process of leveling roll, it looks more light compared with the 2D surface, the instrument measuring the surface roughness of the Ra value is 0.1 ~ 0.5 mu m, is the most common process and have the most extensive application, suitable for the chemical industry.

    What is 2E finish?

    2E. Cold rolled, heat treated, mechanically descaled. Free of scale. Usually applied to steels with a scale which is very resistant to pickling.

    What is a #4 brushed finish?

    4 “Brushed” finishes. This finish provides a nice bright, brushed appearance that will withstand daily use and mask the fingerprints, scuffs, scratches, etc. A bright, cold-rolled finish is the most commonly “Mill” finish for light gauge stainless steel sheet.
