1.6582 (DIN 1654-4 : 1989-10) 34 CrNiMo 6 1.6582 DIN 1654-4 : 1989-10 DIN 1654-4 : 1989-10 replaced by DIN EN 10263-4 : 2002-02 Replaced Germany 34CrNiMo6 1.1.1 1)
1) Remark: The cold-upsettable steel 34 CrNiMo 6 can be cold-formed with the suitable tools with a low to medium rate of forming according to the usual forming methods on single-stage and multi-stage presses. It is used for high-strength screws of strength classes 10.9 and 12.9 in the thick dimension range and for extruded parts with special stress.
