Notes:
1
SCr415 (including corresponding materials of SCr415) is defined as
material equivalent to SCM415.
For carburizing (case hardening), SCM415 is normally used.
If a harder material is required, SNCM220 and/or SNCM420
is normally used.
2
Hardness values are determined by production condition.
For the actual expected hardness value, please refer to the recorded gear quotation.
