Inconel 690 Fasteners

 What are the Inconel 690 Fasteners?

Inconel 690 Fasteners are high-performance nickel-chromium-iron alloy components designed for extreme operating conditions. These specialized fasteners feature exceptional resistance to stress corrosion cracking and high-temperature oxidation. At TSM Technology, we manufacture premium fasteners using Inconel 690 alloy (UNS N06690) with 58% nickel, 28-31% chromium, and 9-11% iron composition. Our fasteners serve critical applications in nuclear power, chemical processing, and petrochemical industries where reliability matters most.

You get superior performance when choosing our precision-engineered solutions. Each fastener undergoes rigorous quality testing to ensure compliance with international standards.
