ASTM B209 5454 Aluminum Plate Supplier Used For Petroleum Tank
Trailer
5454 aluminum is a balanced choice for tanker truck bodies,
offering lightweight, corrosion
resistance, and weldability at a moderate cost.
Key Characteristics of 5454 Aluminum
Alloy Type: Al-Mg (5xxx series, with 2.7-3.5% Mg + 0.5-1.0% Mn).
Corrosion Resistance: Excellent, especially in marine and chemical
environments (saltwater,
petroleum, acidic/alkaline solutions).
Strength: Higher than 5052 but lower than 5083/5086 (typical
tensile strength: 250-350 MPa in
H32/H34 tempers).
Weldability: Easily welded using MIG/TIG methods without post-weld
cracking.
Formability: Good for stamping and bending (better than 5083, but
less ductile than 5052).
Comparison with Other Alloys for Tankers
| Alloy | Mg Content | Strength | Corrosion Resistance | Cost | Best For |
| 5454 | 2.7-3.5% | Medium | Excellent | $$ | General tanker bodies, chemical transport |
| 5052 | 2.2-2.8% | Lower | Very Good | $ | Light-duty tanks, non-chemical liquids |
| 5083 | 4.0-4.9% | High | Exceptional | $$$ | Heavy-duty/offshore tankers, cryogenic tanks |
| 6061 | 0.8-1.2% (Mg-Si) | High (T6) | Good (but prone to SCC) | $$ | Structural frames (not fluid contact areas) |
Why 5454 Over Others?
Vs 5052: Higher strength for pressurized tanks.
Vs 5083: More cost-effective for non-extreme conditions.
Vs 6061: Superior corrosion resistance in wet environments.
Advantages for Petroleum Tank Trailer
✅ Lightweight: ~35% lighter than steel, reducing fuel consumption.
✅ Corrosion Resistance: Withstands petroleum, diesel, and chemicals
without coating.
✅ Durability: Resists stress corrosion cracking (SCC) in welded
joints.
✅ Low-Temperature Performance: Maintains toughness in cold climates
(e.g., LNG transport).
✅ Cost-Effective: Cheaper than 5083/5086 while offering sufficient
strength.
