Alloy 718 Spray Wire 3.17 mm

Alloy 718 Wire for Thermal Spray

Alloy 718 (often referred to by the trade name Inconel 718) is a nickel-chromium-molybdenum-columbium alloy that combines high tensile strength, excellent fatigue life, and good oxidation resistance up to approximately 700 °C (1300 °F). In wire form, it is used to deposit dense, well-bonded coatings on substrates that require protection against heat, corrosion, or wear, or to rebuild worn or mismachined parts.

The 3.17 mm diameter is a common size for twin-wire arc spray systems and larger combustion flame spray setups. Consistent wire chemistry, cast, and helix help maintain stable feed and a uniform spray pattern. Typical coating applications include gas turbine components, pump shafts, valve seats, and other engineering parts operating in aggressive environments.

Coating Purpose and Typical Applications

Alloy 718 coatings are specified where the service environment demands a combination of high-temperature strength and resistance to oxidation or chemical attack. The alloy's ability to be age-hardened after spraying (where process and substrate allow) can further enhance coating hardness and durability.

• High-temperature oxidation and corrosion protection on furnace parts, exhaust systems, and heat exchangers.
• Dimensional restoration and repair of worn shafts, bearing journals, and flanges on rotating equipment.
• Bond coat or build-up layer in multi-layer coating systems requiring a tough, oxidation-resistant foundation.
• Petrochemical and power generation components exposed to sour gas, steam, or combustion by-products.

Pack Options and Handling

Alloy 718 spray wire is available on 15 kg, 20 kg, and 25 kg spools, as well as coil packs to suit different equipment pay-off systems. Spools are precision-wound to ensure snag-free dereeling during continuous spray operations. Buyers should specify preferred pack type and weight at the time of enquiry to confirm current stock and lead time.

Store wire in a dry, covered area and keep spools in their original packaging until use to prevent surface contamination. Any surface rust, oil, or dirt on the wire can introduce defects into the sprayed coating. If wire has been exposed to moisture, consult your process specification before use.
