Stainless Steel 321 Tube Manufacturer, ASTM A213 TP321 Seamless Tube Supplier & Exporter
Specification
Chemical Composition
Stainless Steel 321 Tube is a titanium-stabilized austenitic stainless steel tubing designed for high-temperature service where resistance to intergranular corrosion is essential. Commonly manufactured according to ASTM A213 TP321 Seamless Tube and ASME SA213 TP321 Tube standards, these tubes offer excellent oxidation resistance up to approximately 870°C and are widely used in heat exchangers, condensers, boilers, petrochemical plants, refineries, aerospace, food processing, and power generation industries.

What is Stainless Steel 321 Tube?
Stainless Steel 321 Tube is an austenitic chromium-nickel stainless steel stabilized with titanium. The addition of titanium prevents chromium carbide precipitation during welding and high-temperature exposure, making the alloy ideal for continuous service between 425°C and 870°C.
Compared to Grade 304 stainless steel, SS 321 offers significantly better resistance to intergranular corrosion after welding while maintaining excellent toughness, formability, and weldability.
The commonly used specifications include:
- ASTM A213 TP321 Seamless Tube
- ASME SA213 TP321 Tube
- ASTM A269 TP321 Tubing
- ASTM A249 TP321 Welded Tube
Equivalent grades include:
- UNS S32100 Tube Equivalent
- UNS S32109 / 1.4878 Tube
- Werkstoff Nr 1.4541 Tube
