1) Remark: Steel CK 25 is suitable for low strained parts in vehicle manufacturing and machine engineering with higher dimension and complexer forms as well as higher requirements to uniformity of qualities and surface appearance (e.g. transmission parts, crankshafts). Lowest application temperature -25 °C.
