BA stainless steel coil refers to stainless steel coil that has been processed with a Bright Annealed (BA) finish. This finish is achieved by annealing the material in a controlled atmosphere furnace, which prevents oxidation and produces a smooth, bright, reflective surface. common grades include 201,304,316,410 and 430, which are known for their good corrosion resistance, durability, and workability.

What is BA finsh ?
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. This produces a reflective, shiny, smooth surface structure which, depending on the manufacturer and batch, can be close to a mirror-polished stainless steel of the lower quality grades.
