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。REX M42是一种高速钢，可热处理至68洛氏C硬度。其更高的硬度使其特别适用于要求超出通用高速钢能力的特殊刀具。采用坩埚颗粒冶金工艺生产的CPM REX M42是一种质量更高的产品，具有均匀的宏观和微观截面，与传统生产的M42相比，在热处理条件下表现出更细的晶粒尺寸、更好的韧性和优异的可磨性。这两种产品的其他特性和性能非常相似（见一般特性）。

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.REX M42 is a high-speed steel that can be heat treated to 68 Rockwell C hardness. Its higher hardness makes it outstanding for special-cutting tools with requirements beyond the capability of general-purpose high-speed steels. CPM REX M42, produced by the Crucible Particle Metallurgy Process, is an improved quality product with homogeneous macro and micro sections exhibiting a finer grain size, better toughness and superior grindability in the heat-treated condition than conventionally produced M42. Other characteristics and properties of the two products are very similar (See General Characteristics).
