Gangyan Gaona applies for patents related to GH3536 rod preparation, with a new method solving the carbide residue problem in large-sized GH3536 rods

April 2 News, the State Intellectual Property Office information shows that Beijing Steel Research High-Nano Technology Co., Ltd. has applied for a patent titled “A Preparation Method for Controlling Carbide Distribution in Large-Size GH3536 Alloy Bars.” The application publication number is CN121759842A, the application number is CN202411381601.1, the publication date is March 31, 2026, the filing date is September 30, 2024, inventors are Gu Yu, An Teng, Chi Hai, Duan Fangzhen, the patent agency is Beijing Tianda Intellectual Property Agency Co., Ltd., patent agent Zhao Yangyang, classification number C22F1/10.

The patent abstract indicates that the invention relates to a preparation method for controlling carbide distribution in large-size GH3536 alloy bars, belonging to the field of large-size bar preparation methods. It addresses the issue that traditional preparation methods for small-diameter GH3536 alloy bars below 300mm are not suitable for producing large-size GH3536 alloy bars, and that during preparation, problems such as carbide band residue easily occur, leading to poor performance. The invention proposes a new preparation method for large-size GH3536 alloy bars, solving the problem of carbide band residue commonly generated by traditional methods, and providing the possibility for the market application of large-size GH3536 alloy bars.
