Material Description

Material Number	Material Number (single)	Standard	Range of Application	Standard Status	Country	Successor	Remark
1.1224 (DIN EN 10132-4 : 2003-04)	1.1224	DIN EN 10132-4 : 2003-04	DIN EN 10132-4 : 2003-04 replaced by DIN EN 10132 : 2021-11	Replaced	Germany	C125S	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.
