The material under consideration exhibits ferrite and pearlite characteristics before heat treatment, which are transformed into martensite characteristics after heat treatment. This material offers ultra-high strength, with a tensile strength exceeding 1500 MPa, making it an ideal choice for safety structures such as front and rear bumpers, A-pillars, B-pillars, and middle passages. The use of this material improves crash performance and lightens the body, while also offering good formability with complex shapes and high dimensional accuracy. Overall, the material’s combination of characteristics makes it highly suitable for applications where safety and high performance are critical.
