EN 10277-5 Grade Ck35 Cold‑Drawn Steel – Superior Strength for Automotive & Industrial Applications
Steel CK 35 is suitable for a little higher strained parts in vehicle manufacturing and machine engineering with higher dimensions (heavy forged parts) and complexer forms as well as higher uniformity requirements on qualities and surface appearance (e.g. transmission parts, crankshafts). Lowest application temp. -25 °C, good creep behaviour up to 480 °C.
