Stainless 304 Spray Wire 3.17 mm

About Stainless 304 Spray Wire

Stainless 304 (UNS S30400) is an austenitic chromium-nickel alloy widely used in thermal spraying for its balance of corrosion resistance, mechanical properties, and cost-effectiveness. When sprayed, it forms a dense, oxidation-resistant coating that can be finished by machining or grinding. The 3.17 mm diameter is a standard size for many arc spray and flame spray guns, offering a practical feed rate and stable arc characteristics.

Coating Purpose and Performance

This wire is selected for applications where the coating must withstand mild chemical exposure, atmospheric corrosion, or moisture. It is also used as a dimensional build-up layer before applying a harder top coat. The as-sprayed coating has a typical stainless steel appearance and can be sealed for enhanced corrosion protection in aggressive environments.

Spray Process Compatibility

The 3.17 mm diameter is commonly used in electric arc spray systems and large-wire flame spray torches. Arc spraying with this wire produces a high bond strength coating with moderate oxide content. Flame spraying offers a smoother as-sprayed finish. The exact process fit depends on your gun model, nozzle setup, and drive roll configuration. SPA2Z recommends confirming compatibility with your equipment supplier or our technical team before ordering.

Pack Options and Handling

SPA2Z offers this wire in multiple pack formats to suit different production volumes and equipment setups:

• 15 kg spool — convenient for job shops and intermittent use
• 20 kg spool — balanced option for regular production
• 25 kg spool — higher volume, fewer changeovers
• Coil pack — for systems that accept coil-fed wire

Wire is wound with controlled tension to ensure smooth, snag-free feeding. Store in a dry, covered area to prevent surface oxidation before use.
