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。Armco 420是一种铁铬不锈钢，添加了碳含量（0.3%标称值）以获得更高的硬度。该合金在退火状态下为铁素体，在高于临界温度的空气或液体介质中快速冷却后为马氏体。

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.Armco 420 is an iron-chromium stainless steel with added carbon content (0.3% nominal) for higher hardness. The alloy is ferritic in the annealed condition and martensitic after rapid cooling in air or a liquid medium from above the critical temperature.
