Abstract:
The present invention relates to a high carbon hot rolled steel sheet having excellent material uniformity and a method for manufacturing the same, in which components and structure of the steel are precisely controlled and manufacturing conditions are adjusted to achieve excellence in material uniformity among hot rolled structures, thereby improving the dimensional precision of parts after formation, preventing defects during processing, and obtaining uniform structures and hardness distribution even after a final heat treatment process.
