Ideal Auto's self-developed high-strength and tough stainless steel successfully rolled off the production line

Li Auto's first self-developed high-strength stainless steel coil was successfully rolled off the production line at Qingtuo Group on December 12. The strength of this new type of stainless steel is 46% higher than that of traditional stainless steel, and its stress corrosion resistance is significantly improved. This material will be used in high-pressure stainless steel fuel tanks in Li Auto's L-series models, thereby greatly improving the safety performance of the fuel tanks under extreme working conditions.
