COBALT L605 per GE B50A460 S3
GE B50A460 S3 is a material specification for L605, also known as Haynes 25, which is a cobalt alloy in sheet form. This alloy has superior high temperature properties, oxidation resistance, and wear resistance, and it is commonly used in the manufacture of gas turbine engine parts and in the aerospace industry in general.
Product Forms & Size Range
L-605 Plate Thickness ranges from 0.1875″ to 2.50″ Thick
L-605 Sheet Thicknesses range from 0.002″ to .156″ Thick.
Overview of L605 per GE B50A460 S3
L605, when aligned with the GE B50A460 S3, offers excellent performance up to 1500°F (816°C) and oxidation resistance up to 2000°F (1093°C). The solution heat treatment occurs at a range of 2150°F to 2250°F (1175° to 1230°C), followed by rapid cooling by air or water quench to achieve a grain structure that provides stability.
