Problems solved by technology

[0002] Hot work die steel has good thermal fatigue resistance and thermal stability. The working conditions of hot work die steel are relatively simple and complicated. When the service temperature exceeds 600°C, the original excellent performance will be lost due to insufficient heat resistance. Hot steel has poor toughness and poor fatigue resistance, and the mold often cracks and fails early, which greatly increases the production cost and cannot meet the needs of enterprises.

Description

Technical field [0001] The invention relates to a hot work mold. Background technique [0002] Hot work die steel has good thermal fatigue resistance and thermal stability. The working conditions of hot work die steel in service are simple and complicated. When the service temperature exceeds 600 ℃, it will lose its original excellent performance due to insufficient heat resistance and high resistance. Hot steel has poor toughness and poor fatigue resistance, and molds often crack and fail early, which greatly increases production costs and cannot meet the needs of enterprises. [0003] Therefore, in order to solve the above problems, a new technical solution is provided. Summary of the invention [0004] The invention provides a hot work mold. [0005] The technical scheme adopted by the present invention is: [0006] A hot work mold, including the following parts by weight: [0007] Carbon 0.15-0.36 parts; [0008] 0.03-0.08 parts of oxygen; [0009] 0.3-0.45 parts of copper; [0010] ...
