[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.

Abstract
The invention relates to a hot work die, which comprises the following components by weight part: 0.15-0.36 parts of carbon, 0.03-0.08 parts of lithium, 0.3-0.45 parts of copper, 0.06-0.18 parts of calcium, 0.1-0.5 parts of aluminum, 0.04-0.67 parts of caesium, 0.4-0.8 parts of phosphor, 0.25-0.36 parts of potassium and 95-98 parts of iron. The hot work die has the advantages that the composition proportion is scientific and reasonable, heatproof effect is good, crack phenomenon can not be generated after long-term usage, fatigue resistance is good, production cost is greatly reduced, and enterprise requirement can be satisfied.
Description
technical field [0001] The invention relates to a hot working mold. Background technique [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 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. Contents of the invention [0004] The invention provides a hot working mold. [0005] The technical scheme adopted in the present invention is: [0006] A hot work mold, comprising the following components by weight: [0007] Carbon 0.15-0.36 parts; [0008] Lithium 0.03-0.08 part; [0009] Copper 0.3-0.45 parts; ...
