The Grades Of Stainless Steel Plates Are Indicated
Oct 25, 2017

(1) Cold-rolled non-oriented silicon steel strip (sheet) Description: DW + iron loss value (in the frequency of 50HZ, the waveform is sinusoidal magnetic flux of 1.5T per unit weight of iron loss.) 100 times + thickness value 100 times. Such as DW470-50 said iron loss value of 4.7w / kg, thickness of 0.5mm cold-rolled non-oriented silicon steel, the new model is expressed as 50W470.

(2) Cold-rolled oriented silicon steel strip (sheet) Description: DQ + iron loss value (in the frequency of 50HZ, the waveform is sinusoidal magnetic induction value of 1.7T per unit weight of iron loss.) 100 times + thickness value of 100 Times Sometimes iron loss after the addition of G that high magnetic induction. Such as DQ133 said iron loss value of 1.33, thickness of 0.3mm cold rolled oriented silicon steel strip (film), the new model is shown as 30Q133.

(3) hot-rolled silicon steel plate hot-rolled silicon steel plate with DR said, according to the number of silicon is divided into low silicon steel (silicon content ≤ 2.8%), high silicon steel (silicon content> 2.8%). Representation method: 100 times the DR + iron loss value (100 times + thickness value per unit weight of iron loss with 50HZ repeated magnetization and maximal magnetic induction intensity at 1.5T). Such as DR510-50 said iron loss value of 5.1, the thickness of 0.5mm hot-rolled silicon steel plate. The grades of hot-rolled silicon steel sheets for household appliances are represented by JDR + iron loss + thickness values, such as JDR540-50.
