NON-ORIENTED ELECTRICAL STEEL SHEET - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240035130 titled 'NON-ORIENTED ELECTRICAL STEEL SHEET
Simplified Explanation
The abstract of the patent application describes a non-oriented electrical steel sheet with a specific chemical composition that allows for α-γ transformation. The composition includes a maximum of 0.010% of carbon (C), 1.50% to 4.00% of silicon (Si), 0.0001% to 1.0% of soluble aluminum (sol. Al), a maximum of 0.010% of sulfur (S), a maximum of 0.010% of nitrogen (N), and a total of 2.50% to 5.00% of at least one element selected from the group consisting of manganese (Mn), nickel (Ni), and copper (Cu). The remaining composition includes iron (Fe) and impurities. The average grain size of {411} crystal grains is defined as d, and the average grain size of {111} crystal grains is defined as d. The ratio of d/d is required to be greater than or equal to 1.10.
