  • NACE MR0175 (Optional for Sour Service)

• Material Code: UNS S32109 | W.Nr. 1.4541

 

2. Chemical Composition (%)

Element	Min	Max	Role
Chromium (Cr)	17.0	19.0	Oxidation Resistance
Nickel (Ni)	9.0	12.0	Austenitic Stability
Carbon (C)	0.04	0.10	High-Temp Strength
Titanium (Ti)	5×C%*	0.70	Prevents Sensitization
Manganese (Mn)	-	2.0	Deoxidation
Silicon (Si)	-	0.75	High-Temp Creep Resistance
Phosphorus (P)	-	0.045	Purity Control
Sulfur (S)	-	0.030	Machinability

(*Ti ≥ 5 × Carbon content for carbide stabilization during welding/heat exposure)

 

3. Dimensions & Tolerances

• OD Range: 6mm - 150mm (Seamless, Cold-Drawn/Hot-Finished)

• Wall Thickness: 1mm - 20mm (±10% per ASME SA1016)

• Length: 6m - 12m (Standard), Custom Lengths up to 18m

• Surface Finish:

  • Annealed & Pickled (Standard)

4. Key Properties & Performance

 High-Temp Resistance:

• Continuous Service: Up to 816°C (1500°F)

• Oxidation Resistance: Superior to 304H due to Ti stabilization
   Weldability: Low risk of weld decay (sensitization) in HAZ (Heat-Affected Zone)
   Corrosion Resistance: Good against organic acids, steam, and mild oxidizing environments

 

5. Manufacturing & Testing

• Process:

  • Hot Extrusion → Cold Drawing → Solution Annealing (1050-1150°C) → Water Quenching

• Testing:

  • Hydrostatic Test: 100% tested at 70 bar (1015 psi) min

  • PMI (XRF): Alloy verification

  • Hardness Test: ≤192 HB (Annealed Condition)

  • Intergranular Corrosion Test: ASTM A262 Practice E (Oxalic Acid Etch)

  • Ultrasonic/Eddy Current Testing: ASTM E213/E426 for defect detection

 

6. Packaging & Logistics

• Protection:

  • Plastic End Caps + VCI (Volatile Corrosion Inhibitor) Paper

 Petrochemical: Cracking furnaces, reformer tubes
 Heat Exchangers: For steam/hot oil systems
 Nuclear: Auxiliary piping (non-reactor zones)

 

8. Why Choose TP321H Over TP304H?

Property	TP321H	TP304H
High-Temp Stability	★★★★★ (Ti-stabilized)	★★★☆
Weldability	Excellent (No Post-Weld Annealing Needed)	Risk of Sensitization
Oxidation Resistance	Superior (Due to Ti)	Moderate
Cost	10-12% Higher	Baseline
