INCONEL 625（UNSN06625） WIRE
Nickel-Chromium-Molybdenum-Niobium Alloy with High Strength & Corrosion Resistance
INCONEL 625 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 INCONEL 625 in multiple product forms with stable chemistry, consistent mechanical properties, and flexible dimensional customization for global industrial users.
Typical supply range (custom sizes and tolerances available upon request):
Item | Range / Options | Notes |
Diameter | 0.5 – 20 mm | Wire in coils/spools; straight lengths by request (limited sizes). |
Form | Coil / Spool / Straight | Packaging per diameter and customer requirement. |
Surface finish | Bright / Pickled / Descaled | Surface condition per application (forming/welding). |
Packaging | Spools / Coils | Labeling and moisture-proof packing available. |
Tolerance | Per ASTM/EN or as agreed | Define diameter tolerance for precision wire. |
Straightness | As agreed | For straight wire, define straightness and cut length tolerance. |
Delivery condition | Solution annealed (standard) | Annealed & pickled/bright depending on finish. |
Dimension definition: DIA × COIL/SPOOL.
• Excellent resistance to pitting and crevice corrosion in chloride media
• Outstanding resistance to chloride stress corrosion cracking (SCC)
• Strong resistance to oxidizing and reducing acids in mixed process media
• Withstands wet chlorine gas, hypochlorite, and chlorine dioxide solutions
• High chromium content improves resistance to oxidizing media; suitable for use in the as-welded condition
• Good fabrication and welding performance for CPI equipment
Element | Ni | Cr | Mo | Fe | W | Mn | Si | C |
