ASTM A213 TP321 and TP321H Heat Exchanger Tubes are seamless stainless steel tubes designed for use in high-temperature applications, with TP321H having a higher carbon content for enhanced resistance to sensitization. These tubes are commonly employed in industries requiring heat exchange equipment such as boilers and condensers.
ASTM A213 Specification
The ASTM A213 specification covers seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. These ASTM A213 TP321/ ASTM A213 TP321H tubes are produced using cold-drawn or cold-rolled techniques and are widely used in refinery, petrochemical, and power plant applications.
Ss 321 Seamless Pipe Corrosion Resistance
These tubes have excellent corrosion resistance properties and are ideal for use in high-temperature and high-pressure applications. The main difference between TP321 and TP321H tubes is the amount of carbon content present in them. 1.4878 AISI 321H tubes are designed for high-temperature applications and have a higher carbon content than 1.4541 AISI 321 tubes.
SS 321/321H Seamless Tubes Mechanical properties
Both TP321 and TP321H tubes have excellent mechanical properties, including high tensile strength, good yield strength, and good toughness. They are also known for their excellent weldability and formability, which makes them easy to fabricate and install.
- Tensile Strength: ≥ 515 MPa (75,000 psi)
- Yield Strength: ≥ 205 MPa (30,000 psi)
- Elongation: ≥ 35%
- Hardness: ≤ 90 HRB
ASTM A213 UNS S32100 and S32109 tube applications
These heat exchanger tubes are widely used in a variety of industries, such as chemical and petrochemical processing, aerospace, and power generation, where they are used to transfer heat from one medium to another. ASTM A213 TP321 and TP321H are highly resistant to corrosion and can withstand high temperatures and pressure, making them ideal for use in harsh environments.
In summary, ASME SA213 TP321 and TP321H Heat Exchanger Tubes are high-quality products that are widely used in various industries for heat transfer applications. They are durable, corrosion-resistant, and can withstand high temperatures and pressure, making them a reliable choice for any application where heat exchange is required.
