What is 1BA finish?
Finish Description Number 1BA. Cold rolled on polished rolls, annealed in a protective atmosphere retaining the as-rolled surface appearance.
What is the difference between 2B and BA finish?
2B comes out of cold rolling with polished rollers and BA is after annealing in an oxygen-free environment. For the same surface roughness, what changes is the thickness and granularity of the surface oxide (which comes from passivation of the surface, not from oxide scale residues from rolling).
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 BA finish stainless steel?
BA (Bright annealed), is a specific surface finish which is produces by the mills for cold-rolled stainless steels, mainly for the grades AISI 304 and AISI 316 and in thicknesses up to a maximum of 3.0 mm. During its production, the stainless steel is annealed in an inert gas atmosphere after cold rolling.
What is the best finish for stainless steel?
In retail products, particularly kitchen appliances, stainless steel No. 4 finish is one of the most popular finishes available. The choice of surface finish is also important where fabrication processes will be applied. Rough surface finishes are appropriate when the steel will be ground prior to painting and gluing.
What is 2R finish?
2R Finish – Cold Rolled, Bright Annealed & Skin Passed Again, there is only a small difference with previously described surface finishes. In this case, we have the bright annealing process added. It consists of annealing the steel under oxygen-free conditions to protect it from oxidation and scaling.
What Grit is a 2B finish?
120-150 grit
2B material, the finisher would use 120-150 grit belt or drum on the linear finisher to set the scratch and then finish with a fine or 180-220 fleece nonwoven drum or a fine belt.
What are the different stainless steel finishes?
Stainless steel rolled finishes provide both aesthetic and functional advantages for all types of stainless steel applications. These unique steel finishes are available in course, flat, reflective, and non-reflective options, providing enhanced metal protection and lasting visual allure.
How do you get 2B finish?
2B: This is achieved by cold rolling, heat treating and pickling, along with the application of a light rolling at the end in order to achieve a smooth and reflective sheen. Considered the most widely used surface finish, 2B is the basis for most polished and brushed finishes.
What is a #2 finish on stainless steel?
2R Finish – Cold Rolled, Bright Annealed & Skin Passed The resulting stainless steel finish is capable of reflecting clear images. It is very smooth and less likely to harbour airborne contaminants and moisture compared to any other mill finishes.
