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。坩埚CPM Rex M4 HC（HS）是一种采用坩埚颗粒冶金（CPM）工艺制造的高钒高速工具钢。M4的高碳改性（参见合金文摘TS- 264）具有高硬度。它还带有一个大截面零件的高硫改性，以简化可加工性。

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.Crucible CPM Rex M4 HC (HS) is a high-vanadium high-speed tool steel made by the Crucible particle metallurgy (CPM) process. This highercarbon modification of M4 (See Alloy Digest TS-264) has high hardening. It also comes with a high-sulfur modification for large cross-section pieces to ease machinability.
