1) Remark: The cold-upsettable steel 41Cr4 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 normed screws and screws manufactured according to drawings of strength class 8.8 in the thick dimension range of strength class 12.9 in the thin dimension range. Also used for high-strength parts manufactured according to drawings (ball studs).
