了解模具生产厂采用的钢的断裂特性对于钢生产厂及模具设计者有很大帮助,文章介绍了确定断裂韧性值的一种简化的方法,该方法与标准方法有很大相关性,所以可用于日常质量检验。 为使其产品精确并可靠,塑料注入成型用的模具的生产厂要求并期望他们采购的型腔钢应具有所希望的综合特性、包括完好性、洁净性、组织均匀性、淬透性、对热处理的安全及可预测的响
Understanding the fracture characteristics of steels used in tooling plants can be of great help to steel manufacturers and mold designers. The article presents a simplified method for determining fracture toughness values that is highly relevant to standard methods and is therefore available In the daily quality inspection. To make their products accurate and reliable, the manufacturer of the molds for plastic injection molding require and expect that the cavity steel they purchase should have the desired combination of properties including integrity, cleanliness, homogeneity, and hardenability, Safe and predictable response to heat treatment
