1.7225 | 42CrMo4 +A Incomplete soft annealing structure

Numeric designation1.7225
Chemical designation42CrMo4
State+A Incomplete soft annealing structure
Etching3% Nital

In this sample, a fully developed soft annealing structure could not be achieved.
Instead of being exclusively in the form of spherically embedded carbides, the cementite is still partially present in the lamellar arrangement of the pearlite.
