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。AK Steel 439 LT是一种铁素体不锈钢，其抗氧化性和耐腐蚀性均优于409型，因此该合金对许多难以形成的汽车排气应用具有吸引力。 与439型合金相比，这种合金的钛含量较低（见合金文摘SS-874，2003年2月），表面基本上没有钛垢。

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.AK Steel 439 LT is a ferritic stainless steel that has both oxidation resistance and corrosion resistance superior to Type 409, making the alloy attractive for numerous difficult-to-form automotive exhaust applications. The lower titanium content of this alloy compared to Type 439 (see Alloy Digest SS-874, Feb 2003) provides an improved surface essentially free from titanium scale.
