1.1274 (DIN EN 10132-4 : 2003-04)	1.1274	DIN EN 10132-4 : 2003-04	DIN EN 10132-4 : 2003-04 replaced by DIN EN 10132 : 2021-11	Replaced	Germany	C100S	The steel C100S 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 C100S are suitable for highly stressed tension springs, especially in the watch industry, as well as for pen nibs.
