heat treated ground bar

heat treated ground bars s45c

heat treated ground bars s45c- base metal : s54c

- high frequency quenched

- hardness : hrc55- 60

- hardening layer : 0. 8 mm - 3 mm

- surface roughness : <1. 65

- diameter tolerance: g6 (g5)

The inside stress is removed by high- frequency heat- treatment in

the wake of the hardened layer. possible flaws and corrosion are

thoroughly inspected. Effictive depth of hardened layer according to

the size of the shaft is maintained
