EN 10277-2 Grade C35 Cold-Drawn Steel – High Strength, Low Temperature Performance
Steel C35 is suitable for parts of slightly higher strength requirements and still low ductility requirements in vehicle, engine and machine engineering (e.g. gears, bolts, clutch parts). Lowest application temperature -25°C, favorable creep behaviour up to 480°C. As a bright steel product it is used in the form of bars, bright, straight, in various conditions (see DIN EN 10277 : 1999-10).
