The prerequisite, however, was to develop a steel that had a high
surface hardness and at the same time had sufficiently high
suspension properties to be able to elastically absorb shock loads
that always occur during operation.
characteristics
It is an oil hardening steel intended for rotary hardening. It is
therefore fundamentally ruled out for similar processes insofar as
water has to be used for quenching.
The steel has the following average composition:
C Mn Cr Mo V
0.60% 0.90% 1.00% 0.20% 0.07%
Compliance with special metallurgical conditions and the
introduction of suitable test procedures are necessary in order to
achieve constant properties of the steel as a prerequisite for the
rotary hardening process.
CV 58 Z is supplied in the annealed or quenched and tempered
condition.
