Alloy 625 Spray Wire 2.3 mm

About Alloy 625 Thermal Spray Wire

Alloy 625 is a nickel-based superalloy known for its exceptional resistance to pitting, crevice corrosion, and stress-corrosion cracking. As a thermal spray wire, it is widely used to apply protective coatings on steel substrates exposed to seawater, acids, and high-temperature oxidation. The 2.3 mm diameter is a common size for twin-wire arc spray systems, offering a balance of feedability and deposition rate.

The coating exhibits high tensile and fatigue strength, making it suitable for both new component protection and dimensional restoration of worn parts. Typical coating hardness and bond strength values depend on spray parameters and can be provided upon application review.

Coating Purpose and Performance

This wire is selected for applications that demand a combination of corrosion protection and mechanical durability. It resists attack from chlorides, sulfides, and oxidizing media up to approximately 980°C (1800°F). Common coating functions include:

• Corrosion barrier: Protects steel structures in offshore, chemical processing, and waste incineration environments.
• Oxidation shield: Maintains integrity on components exposed to cyclic high temperatures.
• Rebuild and repair: Restores dimensions on worn shafts, bearing journals, and pump sleeves before final machining.

Pack Options and Availability

We supply Alloy 625 spray wire on spools and in coils to match different production setups. Standard pack options include 15 kg spools, 20 kg spools, and 25 kg spools. Coil packs are also available for high-volume, continuous-feed operations. Exact wire chemistry, lot certifications, and spool dimensions are shared with every quotation.
