| Steel properties |
| |
Medium carbon steel to be used either
as-treated (quenched and tempered) or as-annealed (normalised),
depending on the level of mechanical characteristics to be
reached. Suitable for surface hardening. |
| |
|
| |
| Applications |
| |
Quality parts for general mechanics:
hydraulic jacks, pistons, axles, pinions for gears, bearings,
etc. |

For grade XC 48 TS, the P content is
0.025% or less and the minimum hardness of the hardened and
tempered layer is 57 HRC according to NF A 35-563/07-83. For
this other possibility, please contact us. |
