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。1990年开发的快切20钢和45钢具有这两种标称碳含量，由于硫含量较高，因此具有最高的可加工性。

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.Developed in 1990, Fast-Cut 20 and 45 steels are available in those two nominal carbon levels and provide the highest level of machinability because of their elevated sulfur levels.
