Technical Notes
- 01Carbon content ranges between 0.08% - 0.22%.
- 02Pre-weld and post-weld heat treatment is generally not required.
- 03Surface hardness can be increased by carburizing (case hardening).
- 04Stress relief annealing is recommended after cold forming.
- 05C20 and C22 grades can be hardened with mild heat treatment.
- 06Standard length is 3 meters, available up to 6 meters on request.
