雷军晒超强钢发明专利证书 再回应小米自研2200MPa超强钢

Core Viewpoint - Lei Jun, during a recent live stream, addressed concerns regarding the self-research of a new high-strength steel technology, emphasizing that it is a product of collaboration between Xiaomi and academic institutions, rather than sourced from suppliers [1][3] Group 1: Technology and Innovation - The high-strength steel, known as "2200MPa hot-formed steel preparation process," was developed in collaboration with Professor Wang Guodong's team from Northeast University and Yucaitang [1] - The technology has been patented, with the patent number made publicly available for verification [1] - The steel's tensile strength is significantly higher than the industry standard of 1500MPa, achieving a tensile strength of 2200MPa, which enhances the load-bearing capacity of vehicle components [2][3] Group 2: Performance Improvements - The use of this super steel improves the front door's load-bearing capacity by 52.4% and enhances the B-pillar's impact resistance by 70.5% compared to conventional high-strength steel [2][3] - The patented material has already been applied to critical load-bearing parts of the Xiaomi YU7, including the A-pillar, B-pillar, and four door crash beams [2][3]
