ASTM A213 TP304 Stainless Steel Tube Supplier & Exporter in India

ASTM A213 TP304 stainless steel tube is an austenitic stainless steel tube specifically designed for boilers, superheaters, and heat exchangers operating under high temperature and pressure conditions. Manufactured under ASTM A213 / ASME SA213 specifications, TP304 tubes provide an excellent balance of corrosion resistance, heat resistance, and mechanical strength.

Containing approximately 18% chromium and 8% nickel, TP304 offers strong resistance to oxidation and general corrosion. Its high-temperature performance and excellent fabrication characteristics make it one of the most widely used stainless steel grades in thermal and process industries.

Key Features of ASTM A213 TP304 Tube

  • Excellent Corrosion Resistance
    Resists oxidation and corrosion in steam, water, and mild chemical environments, ensuring long service life.
  • High Temperature Strength
    Retains structural stability and mechanical performance in elevated temperature boiler applications.
  • Strong Mechanical Performance
    Minimum tensile strength of 515 MPa and yield strength of 205 MPa allow safe operation under pressure.
  • Superior Fabrication Properties
    Excellent weldability and formability enable easy fabrication without compromising corrosion resistance.
  • Clean & Hygienic Surface
    Smooth finish suitable for clean fluid handling and sanitary environments.
