ASTM A269 / ASME SA269 TP316L Polished 320 Grit Bright Annealed Stainless Steel Tube
Bright Annealing is a process in which the stainless steel surface is made reflective like a mirror. This type of Annealing is produced by heat-treating steel with a controlled atmosphere furnace. ASTM A269 can be buffed to attain a better reflective finish and is used in reflective surface requiring applications. It should be taken into consideration that during Bright Annealing it is necessary for the metal surfaces to be clean and free from foreign contamination for maximum effect. SS 316L Tubes is an improved version of Alloy 304, with the addition of molybdenum and slightly higher nickel content. The resultant composition of AISI 316L Tubes gives the steel much increased corrosion resistance in many aggressive environments.
Bright Annealing Process of Stainless Steel Tube: Bright annealing is a critical production process. If proper annealing is not done tube surface can crack, stained and may lead to easy corrosion. In this process the stainless tube is heated to high temperatures in presence of inert gases. Annealing is done to reduce the hardness of the steel to attain ductility for further processing.
