随着模具向着多功能、高精度、高效率和高寿命发展,对模具性能提出了越来越高的要求。原有的模具钢种已远远不能满足日益增长的模具品种和质量的要求。因此研究、开发新型的模具钢,已经成为世界模具钢的重要发展趋势。在此新形势下,我国已制订了“先进的推广、落后的淘汰、重复的合并、空白要填补”的研制模具钢政策。除在“六·五”期间研制成功了一批模具钢新钢种外,还决定在今后10年用50％的新钢种代替老钢种。特别是对目前还属空白的塑料模具钢、压铸模具钢等要迅速填平补齐并形成系
With the mold toward the multi-functional, high precision, high efficiency and high life expectancy, the performance of the mold has put forward higher and higher requirements. The original mold steel has been far unable to meet the growing variety of molds and quality requirements. Therefore, research and development of new mold steel has become an important trend of the world mold steel. Under this new situation, our country has formulated a policy of “developing advanced steel molds, eliminating outdated products, duplicating mergers and filling up gaps”. In addition to successfully developing a batch of new mold steel grades during the “June 5” period, it also decided to replace the old steel grades with 50% of the new steel grades over the next 10 years. Especially for the current is still a blank plastic mold steel, die-casting mold steel, etc. to fill and quickly fill and form
