INCOLOY 825（UNSN08825） WIRE

Nickel-Iron-Chromium-Molybdenum-Copper Alloy for Superior Acid and Chloride Corrosion Resistance

INCOLOY 825 wire is supplied for corrosion-resistant fasteners, springs, woven mesh, and also as welding wire/filler applications where compatibility with C-22 base metal is required. The alloy maintains excellent corrosion resistance in both oxidizing and reducing environments and is suitable for demanding chemical process and pollution-control services.

As a professional Chinese nickel-based alloy manufacturer, we supply INCOLOY 825 in multiple product forms with stable chemistry, consistent mechanical properties, and flexible dimensional customization for global industrial users.

Sizes, Finishes & Processing (Wire)

Typical supply range (custom sizes and tolerances available upon request):

                                                          Dimension definition: DIA × COIL/SPOOL.

Key Characteristics

• Excellent resistance to sulfuric and phosphoric acids across wide concentration ranges
• Strong resistance to chloride stress corrosion cracking and crevice corrosion
• Good resistance to reducing and oxidizing media; performs well in mixed acid systems
• Molybdenum and copper enhance resistance to reducing acids and pitting environments
• Titanium stabilization improves resistance to intergranular corrosion after welding
• Good fabricability and weldability for chemical process equipment

Chemical Composition (wt.%)

Extremely low carbon and silicon help maintain corrosion resistance in as-welded structures.

Mechanical Properties (Room Temperature, Typical)

Mechanical properties may vary slightly with product form and heat treatment condition.
