How strong is the 'Xiaomi Super Strong Steel'? Where exactly does it 'strong' lie?

Question

The 2200MPa Xiaomi Super Strong Steel is the highest strength hot-formed steel currently in mass production in the industry, significantly improving vehicle safety.

Accepted Answer

The "2200MPa Xiaomi Super Strong Steel" is currently the highest strength hot-formed steel in mass production in the industry. The "2200MPa Xiaomi Super Strong Steel" was jointly developed by Xiaomi Auto, Academician Wang Guodong's team, Yucaitang, and Northeastern University, combined with Xiaomi AI models, screened from 24.43 million formulas, and performs excellently in terms of performance:
Compared to 1500MPa hot-formed steel, its tensile strength is increased by 40% and yield strength by 24%;
We applied it to the four-door anti-collision beams of the Xiaomi YU7. Compared to 1500MPa door anti-collision beams, the load-bearing capacity of the Xiaomi YU7 front door anti-collision beam is increased by 52.4%, and the rear door anti-collision beam by 37.6%;

We also embedded 2200MPa Xiaomi Super Strong Steel gas-expansion tubes in the A/B pillars of the Xiaomi YU7, forming an "embedded roll cage," increasing the load-bearing capacity of the A-pillar by 35% and the B-pillar by 70.5%;

The above applications of "2200MPa Xiaomi Super Strong Steel" effectively improve the safety of the vehicle in harsh conditions such as side collisions and rollovers.
Xiaomi Auto always takes the strictest safety standards as the design goal, and we also hope that more and more models in the industry will apply stronger body materials in the future, continuously improving vehicle safety levels.
