M130-275 steel is a cold-rolled oriented electrical steel. Grain-oriented electrical steel is a special type of steel designed for electrical applications. This steel has a high silicon content and a grain structure oriented by a magnetic field. This makes this steel ideal for use in transformer cores and other electrical equipment where magnetic properties are important.
Grain-oriented electrical steel typically has a silicon content of 2.5% to 3.5%. A higher silicon content makes the steel more magnetic, but also makes the steel more difficult to machine. For this reason, grain-oriented electrical steels are generally only used in applications where their magnetic properties are critical.
One of the main advantages of grain-oriented electrical steel is low loss. Grain-oriented electrical steel can help reduce energy loss by up to 50% when used in transformer cores. This can lead to significant savings for both the utility and the electricity consumer.
Grain oriented electrical steels are also very resistant to thermal cycling. This means they can be used in transformer cores that experience frequent temperature changes without losing their magnetic properties.
