Gear Steel


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.

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.
