EN 10277-5 Grade CK22: Cold-Drawn, Turned, Quenched, and Tempered Steel for Automotive & Machine Applications
Steel CK 22 is suitable for low strained parts in vehicle manufacturing and machine engineering with higher dimensions (heavy forged parts) 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.
