Use shaft material

A material different from the shaft material can be entered here. This can be the case, for example, if an otherwise surface hardened shaft was covered at this position during hardening.  This local material is used in the following calculations:

• Shaft calculation according to DIN 743 and FKM (2012)
• Feather key calculation according to DIN 6892
• Interference fit calculation according to DIN 7190
