Pike New Materials applies for patents related to heat treatment of forged parts, with specific heat treatment improving the low-temperature impact toughness of the core of the forged parts.

March 29 news, the National Intellectual Property Administration information shows that Wuxi Parker New Material Technology Co., Ltd. has applied for a patent titled “Heat treatment method for improving the low-temperature impact toughness of low-alloy high-strength forged parts at depth.” The application publication number is CN121737393A, the application number is CN202511983249.3, the publication date is March 27, 2026, the application date is December 26, 2025, and the inventors are Sun Bo, Guo Liang, and Yang Shuai. The patent agency is Beijing Zhongji Weitian Patent Agency Co., Ltd., and the patent agent is Ding Yanhua, classified under C21D1/18, C22C38/04, C22C38/02, C22C38/06, C22C38/12, C22C38/14, C22C38/60.

The patent abstract shows that the invention discloses a heat treatment method for improving the low-temperature impact toughness of low-alloy high-strength forged parts at depth, which includes the following steps: (1) First high-temperature quenching: heating the low-alloy high-strength structural steel forged part to above AC3 temperature by 80–100°C, holding for 1h/25.4mm, transfer time ≤ 90s, and water cooling to room temperature; (2) Second low-temperature quenching: heating the forged part processed in step (1) to above AC3 temperature by 20–40°C, holding for 1h/25.4mm, transfer time ≤ 90s, and water cooling to room temperature; (3) Tempering: holding the forged part processed in step (2) at 500–700°C, air cooling. The invention achieves grain refinement and grain boundary purification through the process combination of “high-temperature quenching + low-temperature quenching + tempering,” significantly improving the low-temperature impact toughness of the core while maintaining high strength and high structural stability.
