With a total of 2 patents to his name, Node's innovations have enhanced the performance and reliability of steel products in various applications.
Latest Patents
One of Node's latest patents is for a galvannealed steel sheet and method for manufacturing the same. This invention provides a galvannealed steel sheet that features an oxide layer with a thickness of 10 nm or larger on the plateau of the coating layer, which is flattened by temper rolling. The use of this galvannealed steel sheet prevents powdering during press-forming and achieves stable and excellent sliding performance. By selecting the area percentage of the plateau of the flattened coating layer to a range from 20 to 80%, and ensuring the coating layer is a single layer of δ phase with the presence of ζ phase, further improvements in sliding performance and anti-powdering properties are realized.
Another significant patent by Node is for a hot-dip galvanized steel sheet and method for producing the same. This process involves rough rolling a steel, followed by finish rolling at a temperature of Ar3 point or more. The finish rolled steel is coiled at a temperature of 700°C or less and then hot-dip galvanized at a pre-plating heating temperature of Ac1 to Ac3. The continuous hot-dip galvanizing operation includes soaking a pickled strip at a temperature of 750 to 850°C, cooling it to a temperature range of 600°C or less at a controlled rate, and ensuring the galvanized strip has a structure primarily consisting of ferrite and martensite.
