Non-magnetic steel energy storage

Can electrical steel be classified based on magnetic properties?

The classification of electrical steel grades based on the magnetic properties is not only insufficient, since the behavior can change at magnetic excitations besides the classification point, e.g., elevated frequency as shown in Figure 1, but it also does not focus on the material itself.

Why should you choose a non-magnetic steel?

Thanks to a unique combination of high chromium, manganese and nitrogen contents as well as low amounts of nickel, we offer a stable austenitic structure that delivers outstanding performance. A key advantage of our non-magnetic steels is their flexibility.

What are non-magnetic steels & alloys?

Production of non-magnetic steels and alloys [2, 3] is one of the key elements of oil and gas machine-building; this production is not put into practice in Russia. These materials are widely used in fabrication of geological

Do magnetization behavior and iron loss affect material parameters for non-oriented electrical steels?

In this work, the correlations between magnetization behavior, iron loss and the most relevant material parameters for non-oriented electrical steels, i.e., alloying, sheet thickness and grain size, are studied on laboratory-produced iron-based electrical steels of 2.4 and 3.2 wt % silicon.

Which non-magnetic steels are used in geological steering equipment?

The producers of geological steering equipment as well as telemetry and measuring systems for drilling noted the complete dependence on delivery of foreign non-mag-netic steels Magnadur 501, Magnadur 601, P550, P650, StaballoyAG17, SLW-3 and their analogues from Western Europe countries and China .

How to design low-loss non-oriented electrical steel for energy-efficient electrical drives?

Thus, material design for low-loss non-oriented electrical steel for energy-efficient electrical drives need to consider the application requirements to account for the operating-point-dependent iron losses and required efficiency. A saving of material, resources, production costs or energy can be enabled, with a consideration of interdependencies.
