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。CPM REX 20是不含钴的新型超高速钢系列中的第二种（第一种见CPM REX 25，合金文摘，1980年7月）。CPM REX 20在热处理响应和工具性能方面与AISI 40型系列高速钢相当，尤其是AISI 42型。 CPM REX 20设计用于需要大切削、高速和进给的加工操作，以及高硬度和耐磨性的难加工材料。典型应用包括镗刀、钻头、齿轮刀具和冲头。

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.CPM REX 20 is the second in a family of new super high-speed steels made without cobalt (For the first one, see CPM REX 25, Alloy Digest, July 1980). CPM REX 20 is comparable to the AISI Type 40 series of high-speed steels, particularly AISI Type 42, in heat-treating response and tool performance. CPM REX 20 is designed for use in machining operations requiring heavy cuts, high speeds and feeds, and for difficult-to-machine materials that are high in hardness and abrasion resistance. Typical applications are boring tools, drills, gear cutters and punches.
