ASTM A213 TP304 Stainless Steel Seamless Tube For Heat Exchanger Condenser

ASTM A213 TP304 Stainless Steel Seamless Tube For Heat Exchanger and Condenser

ASTM A213 TP304 Stainless Steel Seamless Tube refers to a high-quality seamless tube made of stainless steel grade TP304, manufactured in accordance with the standards set by the American Society for Testing and Materials (ASTM). The "A213" specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes.

Let's break down the specifications:

1. Chemical Composition of ASTM A213 TP304 (Weight %)

*(Per ASTM A213 / ASME SA213 Standard)*

2. Mechanical Properties of ASTM A213 TP304

(Typical values at room temperature; may vary slightly based on heat treatment.)

Additional Notes:

• Heat Treatment: Solution annealed at 1040°C – 1150°C (1900°F – 2100°F) followed by rapid cooling (quenching).
• Corrosion Resistance: Excellent resistance to oxidation, acids, and chloride environments.

Equivalent Grades:

• UNS S30400
• EN 1.4301
• JIS SUS 304

3. Manufacturing Process:

Seamless (SMLS): Produced via extrusion or piercing, ensuring no welded seams, making it ideal for high-pressure applications.

4. Standards & Specifications:

ASTM A213: Covers seamless ferritic and austenitic steel tubes for heat exchangers.

Other equivalent standards:

• ASME SA213 (ASME Boiler & Pressure Vessel Code version)
• EN 10216-5 (European standard)
• JIS G3463 (Japanese standard)

5. Why Choose ASTM A213 TP304 Seamless Tubes?

✅ Corrosion Resistance – Excellent against acids, chlorides, and oxidation.
✅ High-Temperature Strength – Performs well up to 925°C (1700°F).
✅ Seamless Construction – No welds, ensuring leak-proof performance under pressure.
✅ Hygienic & Easy to Clean – Ideal for food, pharma, and sanitary applications.

In summary, ASTM A213 TP304 Stainless Steel Seamless Tube is a high-quality, corrosion-resistant tube that is suitable for use in boiler, superheater, and heat-exchanger applications, as well as other scenarios that require a robust material that can handle high temperatures and pressures.
