TP316L Stainless Steel Welded Pipe ASTM A269 1/4 Inch X 0.020 Inch X 20FT SS Tubing
Welded stainless steel tubes are created by forming sheets of steel in a tube shape and then welding the seam. Both hot formed and cold formed processes are used to create stainless tubing, with the cold process producing a smooth finish and tighter tolerances than hot forming. Both processes create a steel tube that resists corrosion, features high strength and durability.
Type316L Welded Precision Stainless Steel Tubing has the same composition as Type 316 except the carbon content is held below 0.03%. Not unexpectedly, its general corrosion resistance and other properties closely correspond to those of Type 316. However, it does provide immunity to intergranular attack in the as-welded condition or with short periods of exposure in the temperature range of 800° - 1500°F. The use of 316L is recommended when exposure in the carbide precipitation range is unavoidable and where annealing after welding is not practical. However, prolonged exposure in this range may embrittle the material and make it susceptible to intergranular attack.
The maximum temperature for scaling resistance in contnuous services is about 1650°F, and 1500°F for intermittent service.
May be susceptible to chloride stress corrosion cracking.
Non-hardenable; non-magnetic in the annealed condition, and slightly magnetic when cold worked.
Improved corrosion resistance to chlorides.
