Recently, the rare earth automotive steel independently developed by Bao Gang United Steel successfully passed the painting certification of a major automaker. This achievement is of great significance, as it marks the first time that Bao Gang United Steel's rare earth automotive steel has smoothly passed the specialized painting certification of an automaker, formally qualifying it for mass supply. This lays a critical foundation for Bao Gang United Steel to further expand its market in the automotive industry.
It is reported that in the supply chain of major automotive steel manufacturers, corrosion resistance in painting is a core entry threshold and also a common technical challenge faced by the entire industry. The automaker involved in this certification has extremely stringent detection standards for corrosion resistance, with the specified corrosion resistance cycle being twice as long as conventional standard requirements.
