“D&P” Super Steel: a Super-Strong and Ductile Multi-phase Steel
- Field
- Advanced Materials
- Patent
- IP00654
Key Problem and Market Opportunity
- Steel is the most widely used metallic materials which can be produced efficiently than any other metallic materials
- Automotive, aerospace and defense applications require steel with ultra-high strength
- However, increasing strength often leads to the decrease in ductility, which is known as the strength-ductility trade-off
- Developing a strong, high tensile and yet highly ductile steel has long been the quest for many researchers
- The world’s AHSS market is estimated to worth US$28 billion in 2017
Key Advantages of the Technology
- Our “D&P” Super Steel is a strong, highly tensile and yet highly ductile steel
- With a simple 4-step low-cost fabrication method which involves warm rolling, annealing, cold rolling and tempering, it is a breakthrough in the steel industry
- It is the 3rd generation AHSS (Advanced High Strength Steel)
| Conventional Steel | “D&P” Super Steel | |
|---|---|---|
| Strength and Ductility | ✗ Limited by “strength-ductility” tradeoff | ✓ Overcome “strength-ductility” tradeoff |
| Raw Material Costs | ✗ High | ✓ Low (~20% of the maraging steel) |
| Weight | ✗ Heavy | ✓ Light |
| Fabrication Process | ✗ Complex | ✓ Simple |
| Manufacturing Scalability | ✗ Low | ✓ High |
