| 1) Remark: The steel C125S is used as cold rolled strip for springs and special applications in thicknesses of up to 6 mm and as tempered cold strip in thicknesses from 0.30 to 3.00 mm. The springs made of steel C125S are suitable for highly stressed tension springs, especially in the watch industry, as well as for pen nibs. |
