Steel
Material 1.1274.
Thanks to the carbon content above 1%, this alloy is ideal for feeler gauges, washers, springs, or wherever corrosion problems are not expected. Carbon steel CK101, cold-rolled, hardened, shiny surface.
Chemical composition:
C = max 1,05% ; Si = 0,15-0,30% ; Mn = 0,30-0,45% ; P = max 0,02% ; S = max 0,02% ; Cr = ca. 0,01%
Material 1.2003.
A small amount of chromium leads to higher wear resistance and better hardening of wide dimensions. This alloy is suitable for small tools thanks to the hardness of 47-51 HRC.
Chemical composition:
C = 0,70-0,80% ; Si = 0,25-0,50% ; Mn = 0,60-0,80% ; P = max 0,03% ; S = max 0,03% ; Cr = 0,30-0,40%
