  • ASME SA249 (Pressure Vessel Code)

  • NACE MR0175 (Sour Service Optional)

  • PED 2014/68/EU (CE Marking for EU)

• Material Code: UNS S31635 | W.Nr. 1.4571

 

2. Chemical Composition (%)

Element	Min	Max	Role
Chromium (Cr)	16.0	18.0	Corrosion Resistance
Nickel (Ni)	10.0	14.0	Austenitic Stability
Molybdenum (Mo)	2.0	3.0	Acid/Chloride Resistance
Titanium (Ti)	5×C%*	0.70	Prevents Sensitization
Carbon (C)	-	0.08	Low Carbon for Welding
Manganese (Mn)	-	2.0	Deoxidation
Silicon (Si)	-	1.0	High-Temp Strength
Phosphorus (P)	-	0.045	Purity Control
Sulfur (S)	-	0.030	Machinability

(*Ti ≥ 5 × Carbon content to prevent carbide precipitation during welding)

 

3. Dimensions & Tolerances

• OD Range: 6mm - 250mm (Seamless Cold-Drawn/Hot-Finished)

• Wall Thickness: 0.5mm - 15mm (±10% per ASTM A1016)

• Length: 1m - 12m (Fixed/Random), Custom Cut-to-Length Available

• Surface Finish:

  • Annealed & Pickled (Standard)

  • Electropolished (For Ultra-Clean Applications, e.g., Pharma)

  • BA (Bright Annealed) Mirror Finish (Aesthetic/Hygienic Use)

 

4. Key Properties & Performance

 Chloride Resistance: Excellent pitting resistance in seawater & brine (Critical Pitting Temp: ≥25°C)
 Acid Resistance: Withstands sulfuric (HSO), phosphoric (HPO), and organic acids
 High-Temp Stability: Serviceable up to 800°C (1472°F) (Intermittent)
 Welding Compatibility: Low carbon + Ti stabilization prevents weld decay (sensitization)

 

5. Manufacturing & Testing

• Process:

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

• Testing:

  • Hydrostatic Test: 100% tested at 6.9MPa (1000 psi) min

  • PMI (XRF): Verify alloy composition

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

  • Eddy Current/UT: ASTM E426/E213 for defect detection

  • Mechanical Tests: Tensile, Hardness, Flaring/Flattening (per ASTM A249)

 

6. Packaging & Logistics

• Protection:

  • Plastic End Caps + VCI Paper Wrapping

  • Wooden Crates for OD < 20mm (Fragile Sizes)

• Loading:

  • 20FT Container: ~15MT (6m lengths)

  • 40HQ Container: ~25MT (12m lengths)

 

7. Applications

 Chemical Processing: Heat exchangers, condensers in HCl/HSO plants
 Oil & Gas: Seawater cooling systems, offshore platforms
 Power Generation: Flue gas desulfurization (FGD) scrubbers
 Pharmaceutical: Sterile tubing for API production

 

8. Why Choose 316Ti Over 316L?

Property	316Ti	316L
Chloride Resistance	★★★★★	★★★☆
Weld Decay Risk	None (Ti-stabilized)	Possible (Low Carbon Only)
High-Temp Strength	Superior (Ti Carbides)	Moderate
Cost	10-15% Higher	Baseline
