How to Anneal Stainless Steel and Other Metals

Is it possible to do annealing on Stainless Steel 316 (ASTM A 213 TP 316) tube size 1/4" OD, 20 SWG or 16 SWG? Can you suggest how to do this? Is it possible to do the same for a 3/8" OD tube of similar thickness? These tubes are usually cold drawn tubes, and annealing is required for relieving stresses developed due to work hardening.

Annealing Stainless Steel types 303, 304, 316, 202. A discussion started in 2002 but continuing through 2019. 2002. Q. We manufacture humidifier tanks out of 304 stainless and anneal these tanks for use with D.I. or R.O. water. Will we get the same enhancements to the chromium oxide layer with annealing as with passivation?

The Bright Annealing of Stainless Steel Tubing

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.

The low carbon chemistry of 316L combined with an addition of nitrogen enables 316L to meet the mechanical properties of 316. Alloy 316/316L resists atmospheric corrosion, as well as, moderately oxidizing and reducing environments.

annealing, carbides, which markedly decrease resistance to intergranular corrosion, are dissolved. Typical ranges of annealing temperatures which vary with composition of the steel are given in Table 2. Since carbide precipitation occurs in the temperature range of 4250C to 9000C , annealing temperature should be maintained safely above this limit.
