Spring steel is a special spring steel, medium carbon alloy steel. This steel has the characteristics of yield strength, high fatigue limit, excellent plasticity, and simple heat treatment process. This steel must be forged first when manufacturing the main parts of the mold to eliminate the stress after forging and make the carbides inside the steel uniform, to avoid or reduce longitudinal cracking of the mold, so that the structure obtained after the final heat treatment is fine and has no directionality of the rolled material. .
