2. Mechanical Properties

  • Tensile Strength: ≥515 MPa (75 ksi)
  • Yield Strength: ≥205 MPa (30 ksi)
  • Elongation: ≥35% (in 50 mm gauge length)
  • Hardness: ≤192 HBW (Brinell) or 90 HRB (Rockwell B).

3. Manufacturing & Heat Treatment

Produced via seamless processes (hot extrusion, rotary piercing).

Solution Annealed: Heated to 1040–1120°C followed by rapid cooling to dissolve carbides and optimize corrosion resistance.

4. Applications

  • Superheaters & Reheaters:

Operate in steam boilers at 450–700°C, where TP321 resists oxidation and creep deformation.

Titanium stabilization prevents intergranular corrosion during cyclic heating/cooling.

  • Boiler Tubes:

Withstand high-pressure steam (up to 925°C continuous) in coal-fired, nuclear, or biomass plants.

  • Ethylene Cracking Furnaces:

Exposed to 800–950°C hydrocarbon streams; TP321 handles thermal cycling and carburization.

  • Catalytic Reformer Units:

Resists sulfidation and chloride-induced stress corrosion cracking (SCC) in hydrogen-rich environments.

  • Heat Exchangers:

Used in sour gas or acidic media due to resistance to pitting and general corrosion.

5. Testing & Compliance

Mandatory Tests: Hydrostatic/nondestructive testing, mechanical tests (tensile, hardness), flattening, flaring, and reverse-flange tests.

Certification: Complies with ASME Section II (Materials) and Section I/VIII (Construction). Markings include standard, grade, size, and heat number.

6. Advantages Over Similar Grades

Superior to TP304/304L in high-temperature applications due to titanium stabilization, preventing sensitization.

Unlike TP347 (niobium-stabilized), TP321 offers better weldability and resistance to oxidation in certain conditions.
