EN 10263-4 Grade 34CrNiMo6 cold drawn, annealed to achieve spheroidized carbides and slightly skin passed introduction
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.
