Unmatched dependability is provided by Inconel 718 Bolts when you require fastening solutions that function flawlessly in harsh environments. These high-end superalloy bolts are designed for demanding industrial, power generation, and aerospace applications where conventional fasteners are unable to tolerate the stress and heat. Our product offers the durability required for mission-critical operations due to its remarkable high-temperature strength and resistance to corrosion. At TSM Technology, we produce these specialty bolts in accordance with the strictest industry guidelines, guaranteeing that your projects will be successful even in the most trying circumstances.
These high-performance fasteners are made from Inconel 718, a nickel-chromium superalloy that has been precipitation-hardened. This unique material combines remarkable mechanical properties with remarkable resilience to high temperatures and corrosive environments. The bolts maintain their strength and integrity up to 1,300°F (704°C). They outperform other high-temperature alloys in terms of weldability and fatigue resistance. They are made of iron, nickel, chromium, and trace quantities of molybdenum and niobium for enhanced performance.

Our bolts meet several international standards, such as UNS N07718 and ASTM B637. All applications will experience uniform quality and performance thanks to these guidelines.
Additionally, we fulfill the requirements of JIS, AISI, GB, DIN, and EN. Every bolt is put through a rigorous testing process to ensure that it satisfies these exacting requirements. For aerospace applications, our quality system upholds ISO 9001, AS9100D, and AS9120 certifications.
These bolts are essential to the aerospace sector for spacecraft parts, gas turbines, and jet engines. They are used in nuclear reactors and steam turbines, which are frequently subjected to high temperatures and pressures, in power production facilities. Their ability to withstand corrosion in challenging chemical conditions is advantageous for petrochemical processing facilities. Their ability to withstand extreme stress and corrosion in seawater is used in marine applications. These bolts are used in the production of medical devices in equipment that needs to be sterilization-resistant and biocompatible.
High-quality raw materials from certified sources are the first step in our production process. To guarantee chemical uniformity across the material, we employ sophisticated melting methods. The fundamental bolt form is shaped by hot forging processes while preserving the ideal grain structure. To your exact specifications, precision machining produces thread profiles and precise measurements. Heat treatment procedures maximize the microstructure's strength and resistance to corrosion. All of our manufacturing runs are consistently high-quality thanks to our more than 100 precision equipment.
Step 1: Preparing high-purity materials. Inconel 718 ingots are prepared for forging following examination.
Step 2: Hot Forging: Material is heated and forged into basic bolt shapes under controlled pressure and temperature.
Step 3: Heat Treatment: Solution annealing and precipitation hardening optimize mechanical properties.
Step 4: Machining: Precision turning and threading create precise dimensions and surface finishes.
Step 5: Last Heat Treatment. The maximum strength and hardness are produced via age hardening.
Step 6: Quality Testing: Before packing, a comprehensive inspection ensures that all standards are met.

Every bolt undergoes comprehensive testing, including tensile strength, yield strength, and elongation measurements. We perform hardness testing to verify proper heat treatment results. Dimensional inspection ensures all geometric requirements are met. Chemical analysis confirms material composition compliance. Ultrasonic testing detects any internal defects or discontinuities. Surface finish inspection guarantees smooth, defect-free surfaces. We provide complete material test certificates (MTC) and SGS test reports with every shipment.
Our state-of-the-art 50,000 facility has eight manufacturing lines and more than 100 precise equipment. With over 14 years of expertise and exports to more than 70 countries, we are aware of your quality demands. As a testament to our dedication to the highest quality standards, we continue to have AS9100D certification for aerospace applications. Competitive prices and steady material availability are guaranteed by our integrated supply chain. Throughout your project, our technical staff offers knowledgeable assistance. For peace of mind, we provide thorough traceability documentation and dependable post-purchase assistance.
With the newest production technologies, TSM Technologies runs three cutting-edge manufacturing sites for Inconel 718 Bolts. Melting, forging, heat treatment, machining, and quality control all have their own spaces in our facilities. The ideal conditions for precise production are maintained in climate-controlled settings. Throughout production, contamination-free processing is guaranteed by sophisticated material handling systems.
