1.8159 (DIN EN 10250-3 : 1999-12) 1.8159 DIN EN 10250-3 : 1999-12 DIN EN 10250-3 : 1999-12 replaced by DIN EN 10250-3 : 2022-07 Replaced Germany 51CrV4 1)
1) Remark: Steel 51CrV4 is suitable for high loaded parts in aircraft, vehicle, engine and machine engineering, that increased tempering resistance and best core qualities as well as high wear resistance are required for (e.g. transmission and joint parts, axles). Further application as spring and tool steel. As a bright steel product the steel is used in the form of bars, bright, straight, in various conditions (see DIN EN 10277 : 1999-10).
