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 4820是一种低碳渗碳钢，名义上含有3.5%的镍和0.25%的钼。这是理想的用途，需要一个强大，坚韧的核心，以及一个高耐磨渗碳外壳。此外，它为非渗碳应用提供了强度和低温韧性的良好组合。

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 4820 is a low-carbon carburizing steel containing nominally 3.5% nickel and 0.25% molybdenum. It is ideal for uses that require a strong, tough core along with a highly wear-resistant carburized case. In addition, it offers a good combination of strength and low-temperature toughness for non-carburized applications.
