ASTM B166 Inconel 617 wire is engineered for extreme environments where conventional alloys fail. At DLX, we provide wire that combines high-temperature strength, corrosion resistance, and durability to serve aerospace, industrial, and chemical processing applications reliably.
Inconel 617 is a nickel-chromium-cobalt-molybdenum alloy designed to maintain strength, ductility, and oxidation resistance under prolonged high-temperature exposure. Its nickel base ensures stability, while chromium enhances oxidation resistance, cobalt contributes to high-temperature strength, and molybdenum improves creep resistance. This balance makes it ideal for aerospace components, heat exchangers, and industrial furnace elements.

In aerospace, Inconel 617 wire is used in turbine engine components, high-temperature springs, and heat exchangers. Its ability to retain mechanical properties at temperatures above 1,000°C ensures reliable performance under extreme conditions.
For heat exchangers in chemical and petrochemical industries, the wire’s corrosion resistance and high creep strength extend service life, reducing maintenance and replacement costs. It performs well in oxidizing, reducing, and mildly carburizing environments, ensuring equipment longevity and operational efficiency.
