Description

ASTM A213 TP321 S32100 STAINLESS STEEL SEAMLESS HEAT EXCHANGER TUBING


Stainless Steel 321 contains titanium (Ti) ≥5× carbon content to prevent chromium carbide precipitation during welding or high-temperature exposure (450–850°C). This stabilization ensures resistance to intergranular corrosion even after prolonged thermal cycling, a critical feature for heat exchangers in refineries and power plants1013. Unlike non-stabilized grades like TP304, TP321 retains corrosion resistance in sensitization-prone environments, making it ideal for post-weld applications without requiring heat treatment

Key Characteristics

  • Corrosion Resistance: Excellent resistance to oxidation and corrosion, especially in environments with exposure to organic and inorganic acids.
  • High-Temperature Strength: Ideal for use in environments up to 900°C due to its superior creep and stress rupture properties.
  • Titanium Stabilization: Prevents carbide precipitation and intergranular corrosion, making it superior to TP304 in high-temperature applications.
  • Weldability: Good weldability without the need for post-weld heat treatment in most cases.


Advantages Over Other Stainless Steel Grades

  • Better High-Temperature Performance than TP304 and TP316 due to its titanium stabilization.
  • Resistant to Sensitization during welding, reducing the risk of intergranular corrosion.
  • Comparable Corrosion Resistance to TP304 but with enhanced durability in extreme environments


Application

Due to its superior high-temperature performance and corrosion resistance, TP321 seamless tubes are widely used in industries such as:

  • Aerospace – High-temperature exhaust systems, jet engine components.
  • Chemical Processing – Acidic and caustic environments requiring long-term corrosion resistance.
  • Petroleum & Refining – Heat exchangers, process piping, and pressure vessels.
  • Power Plants – Superheater tubes, reheater tubes, and boiler components.
  • Food Processing – Used in equipment where resistance to organic acids is needed.
