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。这些图表和可加工性、图表和热处理图表和图表。USS AR300和USS AR350是经济的淬火和回火碳钢，可用于要求良好抗滑动磨损和冲击磨损的应用。 它们由两个等级的钢组成，标称成分大致相同，硬度和强度不同，主要是因为回火温度不同。

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.USS AR300 and USS AR350 are economical quenched-and-tempered carbon steels that may be used for applications requiring good resistance to sliding abrasion and impact abrasion. They comprise two grades of steel with about the same nominal composition, differing in hardness and strength largely because of different tempering temperatures.
