1.1231 (DIN EN 10132-4 : 2003-04) C67S 1.1231 DIN EN 10132-4 : 2003-04 DIN EN 10132-4 : 2003-04 replaced by DIN EN 10132 : 2021-11 Replaced Germany C67S 1.1.1 1)
1) Remark: The steel C60S 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 cold-rolled steel strip for springs possess a very high precision of measurements and very good state of the surface.
