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。ACI型HL是一种奥氏体铁铬镍合金，类似于ACI型HK（合金文摘，1974年12月）；然而，HL型的铬含量较高，使其更耐高温气体的腐蚀，尤其是那些含有大量硫的气体。由于HL或HK等级都可以获得基本相同的高温强度，HL合金的耐腐蚀性得到改善，因此在必须避免过度结垢的恶劣环境下尤其有用。

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.ACI Type HL is an austenitic iron-chromium-nickel alloy similar to ACI Type HK (Alloy Digest, December 1974); however, the higher chromium content of Type HL gives it greater resistance to corrosion by hot gases, particularly those containing appreciable amounts of sulfur. Because essentially equivalent high-temperature strength can be obtained with either the HL or HK grades, the improved corrosion resistance of the HL alloy makes it especially useful for severe service where excessive scaling must be avoided.
