Core Benefits:
| Dimension |
Technical parameters/characteristics |
Comparison with conventional materials (stainless steel/carbon steel) |
| Lightweight |
The density is 2.68g/cm³, and the weight is 1/3 that of stainless steel |
Carbon steel is bulky and expensive to transport and install |
| Corrosion resistance |
Resistant to salt spray ≥ 5000 hours (ISO 9227) and resistant to pH 2-12 media |
Stainless steel needs to be 316L grade (50% cost) and carbon steel needs to be coated |
| Low-temperature toughness |
-196°C impact energy ≥27J (ASTM E23), suitable for LNG storage and transportation |
Carbon steel is embrittlement at low temperature, and stainless steel has a high cost |
| Processability |
The elongation is ≥12%, and it can be welded (ER5356 welding wire), rolled, stamped |
Titanium alloys are difficult to machine, and carbon steel needs to be hot-formed |
