SEAMLESS BRIGHT ANNEALED TUBE ASTM A213 / ASTM A269 COLD ROLLING

SEAMLESS BRIGHT ANNEALED TUBE ASTM A213 / ASTM A269 COLD ROLLING

BA (Bright annealed), is a specific surface finish which is produces by the mills for cold-rolled stainless steels.During its production, the stainless steel is annealed in an inert gas atmosphere after cold rolling.
