查看样本合金摘要数据表（PDF）自1952年以来，合金摘要一直是世界各地使用的金属和合金材料性能数据的主要参考。以图表、图表和表格为特色，这些表格给出了有关成分或特性、物理和机械性能、热处理和可加工性的事实和数字。AL TECH MIAMI是一种可硬化不锈钢（AISI 420型）和一种用于制造塑料模具的工具钢。塑料模具钢的主要要求是耐腐蚀性。某些塑料，如聚氯乙烯，具有很强的腐蚀性，储存的模具经常因出汗的水管线和/或潮湿环境而生锈。迈阿密艾尔科技公司具有良好的耐磨性。它经过熔化和AOD精炼，以确保模具制造商的清洁度和内部缺陷。 它为镜头质量的模具提供了非常好的抛光性。

View Sample Alloy Digest Data Sheet (PDF)Since 1952, Alloy Digest has been the leading reference for materials property data on metals and alloys used throughout the world. Featuring graphs, charts and tables, these sheets give facts and figures on composition or characterization, physical and mechanical properties, heat treatment, and machinability.AL TECH MIAMI is both a hardenable stainless steel (AISI Type 420) and a tool steel for making molds for plastic. A major requirement for plastic mold steel is corrosion resistance. Certain plastics, such as poly-vinyl chlorides, are very corrosive and stored molds often rust from sweating water lines and/or humid environments. AL TECH MIAMI has good resistance to wear. It is melted and AOD refined to assure the mold-maker of cleanliness and freedom from internal imperfections. It provides exceptionally good polishability for lens-quality molds.
