Incoloy 825 wire is a corrosion-resistant superalloy designed for severe chemical and thermal environments:

• Acid Resistance: Exceptional performance in sulfuric, phosphoric, and nitric acids due to high Ni-Cr-Mo-Cu content.

• Localized Corrosion Resistance: Resists pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride-rich media.

• High-Temperature Strength: Retains mechanical integrity up to 540°C, with minimal carbide precipitation.

• Oxidation Resistance: Stable Cr₂O₃ oxide layer prevents scaling in oxidizing atmospheres.

• Fabrication Versatility: Easily welded (TIG, MIG), cold-formed, and machined with standard tools.

• Low Thermal Expansion: Coefficient of 13.7 μm/m·°C (20–100°C) ensures dimensional stability under thermal cycling.

Manufacturing Process:

• Melting: Vacuum induction melting (VIM) followed by electro-slag remelting (ESR) to minimize impurities (S, P < 0.015%).

• Hot/Cold Working: Hot-rolled bars are cold-drawn to precise tolerances (±0.02 mm) using multi-pass dies.

• Heat Treatment: Solution annealing at 925-980°C with water quenching to dissolve secondary phases and optimize ductility.

• Surface Treatment: Electrolytic polishing or bright annealing in hydrogen to enhance surface smoothness.

Quality Control:

• X-ray fluorescence (XRF) for compositional accuracy.

• Ultrasonic testing for internal defects.

• Intergranular corrosion testing per ASTM G28 for sensitization resistance.

The alloy’s superior performance stems from its balanced metallurgical design:

• Nickel Matrix: High Ni content stabilizes the austenitic structure, ensuring ductility and resistance to reducing acids.

• Molybdenum & Copper Synergy: Mo provides resistance to chloride-induced SCC, while Cu enhances sulfuric acid corrosion resistance.

• Titanium Stabilization: Ti combines with carbon to form TiC, preventing chromium carbide precipitation at grain boundaries (sensitization).

• Passive Oxide Layer: Cr and Mo synergistically form a Cr-Mo-O passive film, self-repairing in aggressive media like hot hydrochloric acid.

• Phase Stability: Low carbon content (<0.05%) and Ti addition suppress sigma-phase formation, retaining toughness in welded structures.

Incoloy 825 wire is critical in industries requiring resilience to both corrosive and high-temperature conditions:

• Chemical Processing: Wire mesh for acid pickling tanks, phosphoric acid evaporators, and sulfuric acid reactors.

• Oil & Gas: Downhole wireline components, subsea umbilicals, and sour gas wellhead seals.

• Pollution Control: Scrubber systems, flue gas desulfurization (FGD) components, and waste incineration hardware.

• Nuclear Industry: Fuel rod cladding, reactor coolant system fasteners, and spent fuel handling tools.

• Marine Engineering: Seawater heat exchanger springs, offshore platform bolts, and desalination plant fittings.
