Inconel 825 Bolts – Product Overview
Inconel 825 Bolts are engineered for applications where resistance to both oxidizing and reducing environments is critical. The addition of molybdenum and copper significantly improves resistance to sulfuric and phosphoric acids, while titanium stabilization minimizes the risk of intergranular corrosion after welding.
Unlike many high-temperature nickel alloys, Inconel 825 is primarily selected for its corrosion resistance rather than extreme strength or elevated-temperature performance. The alloy performs exceptionally well in environments containing chlorides, acidic media, seawater, and industrial chemicals.
Because of these characteristics, Inconel 825 Bolts are widely used in offshore platforms, chemical plants, fertilizer facilities, pickling equipment, marine systems, heat exchangers, and pollution control systems.
