Core Viewpoint - The powder high-speed steel market is expanding due to increasing demand in high-end manufacturing sectors such as aerospace and automotive, with the market size in China projected to reach 3.9 billion yuan in 2024, a year-on-year increase of 4% [1][12]. Industry Overview - Powder high-speed steel is produced using powder metallurgy technology, which offers significant advantages over traditional casting methods, such as uniform distribution of carbide particles, leading to improved strength, toughness, and hardness [2][4]. - The production process involves high-pressure inert gas or water atomization to create fine, uniform steel powder, which is then shaped and sintered [2]. Industry Development History - The powder high-speed steel industry has evolved over decades, with the first generation emerging in the 1960s. The introduction of new technologies in the 1990s significantly reduced impurity levels, leading to the second generation, while the third generation, post-2000, features finer steel powder and further improved properties [6][10]. Industry Chain - The upstream materials for powder high-speed steel include hard alloy steel powder, carbon steel, tungsten, molybdenum, chromium, vanadium, and cobalt. The midstream involves the production of powder high-speed steel, while the downstream applications span mechanical processing, automotive, aerospace, and mold manufacturing [8]. Current Industry Status - Domestic production of powder high-speed steel has increased significantly, with a production volume of 15,600 tons in 2018, projected to grow to 19,500 tons by 2024, reflecting a compound annual growth rate of 3.8% [10][12]. Competitive Landscape - International companies like Sandvik, Erasteel, Toshiba Materials, and Kennametal dominate the high-end market, while domestic leaders like Tiangong International are making strides in mid-to-high-end market segments through technological advancements [14]. Key Companies - Tiangong International, established in 1981, is a leading manufacturer of high-speed steel and cutting tools, with a revenue of 4.832 billion yuan in the 2024 fiscal year, a decrease of 6.42% year-on-year [16]. - HeYe Technology, a subsidiary of Antai Technology, specializes in high-speed tool steel and has a broad market presence across various industrial sectors [18]. Industry Trends - Continuous technological innovation is expected to enhance the performance of powder high-speed steel, with a focus on optimizing alloy compositions and improving sintering processes [20]. - The market is becoming increasingly competitive, necessitating domestic companies to strengthen their technological capabilities and brand positioning [21]. - The industry is also moving towards green transformation, with companies adopting energy-efficient production methods and cleaner technologies to reduce environmental impact [23].
