The specific composition and heat treatment process that silicon steel undergoes determine its varying hardness. In comparison to other types of steel, silicon steel, also referred to as electrical steel or transformer steel, generally possesses a relatively low level of hardness. Its hardness usually falls within the range of 150 to 250 on the Brinell hardness scale (HB), which measures the hardness of a material through the indentation of a hard steel or carbide ball. The relatively low hardness of silicon steel enables it to demonstrate favorable magnetic properties while retaining satisfactory mechanical strength.
The hardness of silicon steel varies depending on the specific composition and heat treatment process it undergoes. Generally, silicon steel, also known as electrical steel or transformer steel, has a relatively low hardness compared to other types of steel. Its hardness typically ranges from 150 to 250 on the Brinell hardness scale (HB), which measures the hardness of a material by indenting a hard steel or carbide ball into it. Silicon steel's relatively low hardness allows it to exhibit desirable magnetic properties while maintaining good mechanical strength.
The hardness of silicon steel typically ranges between 40 and 45 on the Rockwell C scale.
