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。AISI M4型是一种高淬透性工具钢，其开发目的是提供优异的耐磨性，这是因为钼钨高速钢中的碳和钒含量高于正常值。建议在需要锋利边缘进行精细切割的地方使用。它是重型切削作业的最佳选择，应始终在或接近其最大二次硬度时使用。典型的应用是铰刀、铣刀、冲头和车刀。

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.AISI Type M4 is a high-hardenability tool steel developed to provide the excellent abrasion resistance that results from higher-than-normal carbon and vanadium in the molybdenum-tungsten high-speed steels. It is recommended where sharp edges are needed for fine cuts. It is an excellent choice for heavy-duty cutting operations and should always be used at or near its maximum secondary hardness. Typical applications are reamers, milling cutters, punches and lathe tools.
