Non-oriented fully processed high strength grades have not only guaranteed magnetic properties but also guaranteed mechanical properties. Typical for these grades are higher strength values compared with the standard grades, both at room temperature and at higher temperature operating conditions. Full magnetic characterisation curves at different frequencies are available on request.

These high strength grades withstand stronger mechanical forces than the standard grades. They are therefore an excellent compromise when a combination of high mechanical strength and low magnetic losses is required.

High strength values, combined with low losses and good permeability, make these grades particularly suitable for high-speed rotating machines.

The above properties are obtained without heat treatment after stamping. The material as supplied possesses all the required magnetic properties.

Guaranteed mechanical properties:

The following table specifies the typical mechanical properties:

These standard grades are available non-insulated or varnished with any of the coating types described in data sheet D28.
