5083 Aluminum Alloy Plates Used In Tanker Chemical Storage Tanks
5083 aluminum sheet belongs to Al-Mg series alloy. It is the
highest strength corrosion-resistant
alloy among practical non-heat-treated alloys. And it is suitable
for welding structures. Also, it is
worth mentioning that 5083 aluminum sheet has good resistance to
seawater and low-temperature
characteristics.
Recommended Tempers & Key Properties
| Temper | Process | Mechanical Properties | Applications |
| H111 | Hot-rolled + annealed | Tensile ≥270MPa, Elong. ≥12% | Deep-drawn heads/cones |
| H112 | Hot-rolled + natural aging | Tensile ≥275MPa, Yield ≥125MPa | General pressure vessel shells |
| H116 | Special stabilization | Tensile ≥290MPa, Yield ≥215MPa | Strong corrosive media (e.g., HCl tanks) |
| H321 | TMCP treatment | Tensile ≥310MPa, Yield ≥230MPa | Cryogenic/high-pressure tanks (e.g., LNG) |
Core Advantages
♦ Corrosion Resistance:
Excellent performance in pH 2-11 range
♦ Superior chloride resistance (outperforms 304 stainless steel)
ASTM G67 test: Weight loss <25mg/cm²
♦ Weldability:
5356/5183 filler wires maintain >90% HAZ strength
Comparison with Alternative Alloys
| Alloy | Pros | Cons | Typical Uses |
| 5083 | Best corrosion resistance, weldable | Not heat-treatable | Tankers, ships, chemical tanks |
| 6061-T6 | Higher strength (310 MPa) | Poor corrosion resistance, requires pre-heat welding | Structural frames, non-corrosive parts |
| 5052 | Lower cost, excellent formability | Lower strength (210 MPa) | Lightweight covers, interior panels |
