HABA C-Stahl
1.1191
C45E+N
Unalloyed tempering steel
HABA C-Stahl is a normalized heat-treated steel with good machinability, surface-hardenable and weldable within limits. Suitable for basic steel components in mechanical engineering, vehicle construction and toolmaking which are exposed to medium stress.
APPLICATIONS
- Base plates
- Table tops
- Tools
- Rack gears
- Jigs
- Setting jigs
