Inconel 825 Fasteners Suppliers & Exporters for USA, Europe & Gulf Projects
Aurum Overseas supplies and exports Inconel 825 fasteners for chemical processing, acid handling, fertilizer, and other corrosion-critical applications. Inconel 825 is a nickel-iron-chromium alloy with molybdenum and copper additions, providing strong resistance to reducing and oxidizing acids.
Inconel 825 fasteners are used where continuous exposure to sulfuric acid, phosphoric acid, chlorides, and other aggressive media can cause material degradation. They help maintain fastening integrity in pipelines, reactors, heat exchangers, storage systems, and pollution-control equipment.
Aurum Overseas supplies Inconel 825 fasteners to major international markets including the USA, Canada, Mexico, UAE, Saudi Arabia, Germany, France, Italy, Spain, Netherlands, Qatar, and Oman, supporting chemical plants, EPC contractors, manufacturers, distributors, and industrial buyers.
Metallurgical Properties of Inconel 825 Fasteners
Inconel 825 combines nickel, chromium, molybdenum, copper, and titanium to provide balanced corrosion resistance across demanding chemical environments. Nickel supports general corrosion resistance, chromium improves oxidation resistance, molybdenum helps resist pitting and crevice corrosion, and copper enhances resistance to sulfuric acid.
This combination makes Inconel 825 fasteners suitable for chemical processing and acid-handling systems where long-term resistance to localized and general corrosion is important.
Chemical Composition of Inconel 825 Fasteners
The controlled composition of Inconel 825 supports its resistance to acids, localized corrosion, and aggressive industrial environments.
| Element | Composition (%) | Functional Role |
|---|---|---|
| Nickel | 38.0 – 46.0 | Corrosion resistance |
| Chromium | 19.5 – 23.5 | Oxidation resistance |
| Iron | Balance | Structural stability |
| Molybdenum | 2.5 – 3.5 | Pitting and crevice resistance |
| Copper | 1.5 – 3.0 | Sulfuric acid resistance |
| Titanium | 0.6 – 1.2 | Stabilization against sensitization |
Mechanical Properties of Inconel 825 Fasteners
Inconel 825 focuses on corrosion resistance and stable mechanical performance rather than extreme strength, making it suitable for demanding chemical environments.
| Property | Value |
|---|---|
| Tensile Strength | 585 – 800 MPa |
| Yield Strength | 220 – 450 MPa |
| Elongation | 30% |
| Hardness | ≤ 200 HB |
Inconel 825 Fasteners for Acid and Corrosive Service
Inconel 825 fasteners provide excellent resistance to sulfuric and phosphoric acids and are suitable for fertilizer, chemical processing, and acid-handling equipment. Their resistance to chloride-containing environments also helps reduce the risk of localized corrosion and stress corrosion cracking.
Typical equipment includes acid storage tanks, scrubbers, pickling lines, pipelines, chemical reactors, and pollution-control systems exposed to aggressive process media.

Inconel 825 vs Inconel 625 Fasteners for Corrosive Applications
Inconel 825 fasteners are preferred where sulfuric acid, phosphoric acid, and chemical-processing resistance are the main requirements. For chloride-rich seawater, offshore, and marine environments, Inconel 625 Fasteners Suppliers & Exporters provide a suitable alternative with stronger resistance to pitting and crevice corrosion.
| Comparison Factor | Inconel 825 | Inconel 625 |
|---|---|---|
| Primary Performance | Acid and chemical resistance | Chloride and marine corrosion resistance |
| Sulfuric Acid Resistance | Excellent | Very good |
| Pitting Resistance | Very good | Excellent |
| Chloride/Seawater Service | Good | Excellent |
| Typical Applications | Chemical, fertilizer, acid processing | Offshore, marine, oil & gas |
| Corrosion Environment | Reducing and oxidizing acids | Chloride-rich and seawater environments |
| Best Suited For | Chemical and acid processing | Marine and offshore service |
