ASTM A554 TP304 Stainless Steel Welded Tube for Architectural Purposes

ASTM A554 TP304 Stainless Steel Welded Tube , for Architectural Purposes

ASTM A554 is the standard specification for welded stainless steel mechanical tubing. It covers tubes intended for mechanical applications where corrosion resistance or aesthetic appeal is important.

TP304 refers to the 304-grade stainless steel, which is widely used due to its excellent corrosion resistance, high strength, and good formability. It is part of the austenitic stainless steel family and contains 18% chromium and 8% nickel, making it highly resistant to oxidation and corrosion.

Key Features of ASTM A554 TP304 Tubes

• Material Composition:

  • Chromium (Cr): 18%-20%.
  • Nickel (Ni): 8%-10.5%.
  • Carbon (C): Maximum 0.08%.
  • Manganese (Mn), Silicon (Si), and minor elements as per ASTM standards.

• Manufacturing Process:

  • Welded (not seamless) tubes are produced by welding stainless steel strips and forming them into tubular shapes.
  • Further processing includes polishing and finishing for aesthetic or functional purposes.

• Applications:

  • Architectural purposes (e.g., railings, handrails).
  • Automotive components.
  • Furniture and fixtures.
  • Structural applications.
  • Food and beverage processing equipment.

• Surface Finish Options:

  • Satin finish.
  • Mirror polish.
  • Brushed finish (depending on the application).

• Key Properties:

  • High corrosion resistance in various environments.
  • Good mechanical strength and durability.
  • Ease of fabrication and welding.
  • Non-magnetic in annealed conditions.
