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。309型（UNS S30900）是一种广泛用于高温环境的奥氏体铬镍不锈钢。它具有良好的抗氧化性和耐腐蚀性。该合金在退火时基本上是无磁性的，在冷加工时变得略微有磁性。它主要用于816摄氏度（1500华氏度）或更高温度下的高温应用，需要抗氧化和/或耐腐蚀。

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.Type 309 (UNS S30900) is an austenitic chromium-nickel stainless steel widely used for elevated-temperature services. It has a good combination of oxidation resistance and corrosion-resisting properties. The alloy is essentially nonmagnetic when annealed and become slightly magnetic when cold worked. It is intended primarily for high-temperature applications at 816 deg C (1500 deg F) or higher where resistance to oxidation and/or corrosion is required.
