Global Nuclear Power Fastener Market Strategic Research Report

Scope of the Report

The global Nuclear Power Fastener market size is predicted to grow from US$ 676 million in 2025 to US$ 997 million in 2032; it is expected to grow at a CAGR of 5.8% from 2026 to 2032.

In 2025, global production of nuclear power fasteners is estimated at 32,900 tons, with an average global market price of approximately US$21,000 per ton. Total global production capacity for nuclear power fasteners is projected to reach 41,000 tons by 2025. The industry average gross margin for this product is 28%-60%.Nuclear power fasteners refer to high-performance mechanical parts used in nuclear power plants to connect and secure pressure-bearing boundaries or critical safety equipment. They are core components ensuring the structural integrity and operational safety of nuclear power plants. According to China's national mandatory standards, they specifically refer to bolts, screws, studs, and nuts used in pressurized water reactor nuclear power plants for nuclear safety levels 1, 2, and 3. These products must be manufactured using specific alloy steels or stainless steels, possessing extremely high strength, precision, and reliability to ensure long-term stable operation under harsh conditions. Their quality directly affects the functional execution of the nuclear power plant's safety system.

The nuclear power fastener industry chain is characterized by its technology-intensive nature and close collaboration. Upstream involves the supply of raw materials such as special steels and non-ferrous metals; midstream is the core manufacturing process, encompassing independent research and development, precision machining, heat treatment, and rigorous testing. Leading domestic companies, such as Dingxi High-Strength Fasteners Co., Ltd., have achieved domestic substitution of key products by leading the formulation of national standards and overcoming "bottleneck" technologies, and have built a nationwide intelligent production network. Downstream, the products directly connect with nuclear power engineering design, construction, and equipment integration units, ultimately being applied to key components such as the main structure and piping systems of nuclear power plants.

Driven by the "dual carbon" goal, nuclear power, as a stable and clean baseload power source, will generate continuous market demand for nuclear power fasteners. The prospects are reflected in two aspects: firstly, the steady growth of the market size, with the Chinese nuclear power high-strength fastener market expected to maintain growth in the coming years; and secondly, a more profound driving force stemming from technological advancements and the deepening of domestic production. With the optimization of third-generation nuclear power technology and the development of fourth-generation reactors, higher requirements are being placed on fastener performance. Domestic enterprises are continuously breaking through foreign monopolies, achieving independent control from raw materials to manufacturing processes. Related products have been successfully applied to several major national nuclear power projects and, leveraging their cost-effectiveness, are entering the international market. The industry is moving towards high-end, intelligent, and globalized development.
