PLATED STEEL MATERIAL - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240043980 titled 'PLATED STEEL MATERIAL
Simplified Explanation
The abstract describes a plated steel material with specific chemical composition and impurity limits. The plating layer contains zinc (Zn) more than 50.00%, aluminum (Al) more than 15.0% and less than 30.0%, magnesium (Mg) more than 5.0% and less than 15.0%, and silicon (Si) 0.25% or more and less than 3.50%. The total amount of impurities is less than 1.00%. The total amount of certain elements (Sn, Bi, In) is less than 1.00%, and the total amount of other elements (Ca, Y, La, Ce, Sr) is 0.02% or more and less than 0.60%. The material satisfies specific formulas related to the ratios of Mg/Si, Si/total amount of certain elements, and (Si/total amount of certain elements) multiplied by (Mg/Si). The x-ray diffraction pattern of the plating layer has a specific diffraction intensity ratio (r1) that satisfies a certain range.
