ASTM A213 / ASME SA213 Stainless Steel 304 Seamless Bright Annealed Tube

ASTM A213 / ASME SA213 Stainless Steel 304 Seamless Bright Annealed Tube

Most stainless steel tubing is heat treated by the bright annealing process, in which the tubing is annealed in a protective medium to prevent discoloration of the bright surface. Since austenitic stainless steel is the most often used tubing material, the heat treatment process is bright annealing of austenitic stainless steel in essence.

Stainless steel pipe and tubing are used for a variety of reasons: to resist corrosion and oxidation, to resist high temperatures, for cleanliness and low maintenance costs, and to maintain the purity of materials which come In contact with stainless.
