Inconel 625 socket set screws are resistant to a wide range of corrosive environments of unusual severity including sulfuric acid, hydrochloric acid, and phosphoric acid.

This characteristic, combined with good corrosion resistance at elevated temperatures and high-temperature stability at 2200°F, means Inconel 625 socket set screws are a great choice for fasteners needed in extreme conditions.

The presence of nickel and chromium make Inconel 625 socket set screws oxidation and carburization resistant. The molybdenum delivers excellent fatigue strength and resistance to stress, pitting and crevice corrosion cracking even when exposed to chloride ions making it an excellent choice for seawater applications. It is commonly used in submerged applications by the Navy on submarines and boats.
