ASTM A269 TP316L / UNS S31603 / 1.4404 Stainless Steel Tube Bright Annealed Tube
ASTM A269 TP316L / UNS S31603 / 1.4404 Bright Annealed Stainless Steel Tube
A STAINLESS STEEL 316L BRIGHT ANNEALED TUBE is a corrosion-resistant pipe defined by its low carbon content (0.03% max) and 2-3% molybdenum, enhancing resistance to chlorides and acids. The "Bright Annealed" finish means it was heat-treated in a controlled, oxygen-free atmosphere, resulting in a smooth, shiny, scale-free surface without needing pickling. This pristine surface is ideal for hygienic, high-purity, and aesthetic applications in industries like pharmaceuticals, food and beverage, and semiconductors, where both superior corrosion resistance and a clean, reflective appearance are critical.
- Superior Corrosion Resistance: Especially against chlorides and in welded conditions.
- Excellent Surface Finish: Clean, smooth, and highly reflective.
- High Hygienic Quality: Easy to sterilize and clean.
- Good Mechanical Properties: Strong and ductile.
- Good Weldability: Can be readily welded using common techniques.
