Description

technical field [0001] The invention relates to a hot work die steel. Background technique [0002] At present, hot work die steel material is one of the foundations and core technologies to realize the modernization of manufacturing industry, and its development level is the main indicator to measure the level of a country's manufacturing industry. Hot work die steel generally operates under quite complex working conditions, and the performance requirements for die steel materials are also quite strict. However, the hot work die steel produced in China has low isotropy and poor uniformity of the structure, and the comprehensive performance index of the produced mold is low, which seriously limits the service life. [0003] Therefore, in order to solve the above problems, a new technical solution is provided to meet the demand. Contents of the invention [0004] The invention provides a hot work die steel. [0005] The technical scheme adopted in the present invention i...
