M700-50A Steel FAQS

What is M700-50A steel?

M700-50A steel is a cold-rolled non-oriented electrical steel used in transformer core production. Characterized by high magnetic permeability and low coercive force, this steel is gaining popularity in various electrical and electronic applications such as transformers and motors.

M700-50A steel is made by adding alloying elements to iron ore during the manufacturing process. The most common alloying element is silicon, which can be added in different percentages to produce steels with different electromagnetic properties. Adding silicon increases the steel’s electrical resistivity, a measure of its ability to resist an electric current. This makes M700-50A steel ideal for transformer cores, which minimize energy losses due to eddy currents.

The magnetic properties of M700-50A steel are also affected by the amount of silicon added. As the percentage of silicon increases, the permeability of the steel decreases. This means that M700-50A steel, which has a high silicon content, is not suitable for applications where magnetic properties are important, such as electric motors and generators. However, they are well suited for electromagnetic shielding as their high resistivity prevents electromagnetic field spillover.

Afterwards, the steel passes through a series of rollers until it reaches the desired thickness. Once the steel is rolled to the correct thickness, it goes through a process called annealing. This helps to increase the toughness of the steel and makes it less prone to breaking during use. Finally, the steel passes through a series of finishing rolls before being cut into coils or plates and sent for further processing.

What are the properties of M700-50A steel?

M700-50A steel is a cold rolled non-oriented (CRNO) electrical steel, which is a special type of steel used in the manufacture of electric motors and generators. CRNO steel is made through a cold rolling and annealing process that gives it its unique magnetic properties.

CRNO steel has several advantages over other types of electrical steel. It has a higher strength to weight ratio and is ideal for use in small electric motors and generators.
