Non oriented silicon steel, 50A1300 and 50A470 produced by Baosteel. Which one is low grade and which is medium grade?
Look at the iron loss, 0.5 of the steel plate. The iron loss of 50A1300 is 1300W/kg, the iron loss of 50A470 is 470W/kg, and the lower the iron loss, the higher the grade. 50A470 is the middle grade.
The greater the iron loss value, the surface silicon steel belongs to the low grade, otherwise it belongs to the high grade. For example, both 50A1300 and 50A470 are non oriented silicon steel with a thickness of 0.5; the iron loss of 50A1300 is 1300W/kg, and the iron loss of 50A470 is 470W/kg. Therefore, 50A1300 is low grade non oriented silicon steel, 50A470 is a high grade non oriented silicon steel, and 50A800 and 50A600 are medium grade non oriented silicon steel.
Both 50A1300 and 50A470 are non oriented silicon steel with a thickness of 0.5; the iron loss of 50A1300 is 1300W/kg, and the iron loss of 50A470 is 470W/kg. Therefore, 50A1300 is low grade non oriented silicon steel, 50A470 is a high grade non oriented silicon steel, and 50A800 and 50A600 are medium grade non oriented silicon steel.
1 and 50A1300 are low grade non oriented silicon steel, and 50A470 is high grade non oriented silicon steel.2, the greater the iron loss value, then the surface silicon steel belongs to low grade, otherwise it belongs to high grade.
