Xiaomi YU7 Boron Steel Applications
Q: What is boron steel, and does Xiaomi YU7 use it?
A: Boron steel refers to hot-formed steel with boron additives, achieving strengths above 500MPa. Xiaomi YU7 employs multiple grades of boron steel, including industry-leading 2200MPa material. Key applications:
Door Impact Beams: 1500MPa-2200MPa steel enhances crash protection by 37.6%-52.4%.
A/B Pillars: 2200MPa steel tubes form an integrated roll cage, boosting pillar strength by 35%-70.5%.
Safety: The steel-aluminum hybrid body improves side-impact and rollover resistance.
Boron steel’s high hardness (10 tons/cm²) and heat-treated durability make it ideal for automotive safety. Xiaomi’s 2200MPa variant, co-developed with academic partners, surpasses traditional 1500MPa steel by 40% in tensile strength.
