About Stainless 304 Spray Wire 2.5 mm

Stainless 304 (UNS S30400) is a widely specified austenitic chromium-nickel stainless steel. When applied as a thermal spray coating, it produces a deposit with good corrosion resistance in mild atmospheric, fresh water, and many chemical environments. The 2.5 mm (approx. 0.098 inch) diameter is a practical size for many production-scale arc spray systems, offering a balance between feed consistency and melt characteristics.

Typical uses include coating mild steel structures for corrosion protection, rebuilding worn or machined undersized stainless steel parts, and applying a compatible base layer before a topcoat in multi-layer spray systems. The coating can be machined or ground to final dimensions after spraying.

Process Compatibility and Selection

This wire is suitable for both electric arc spray and combustion flame spray processes. Arc spray typically provides higher deposition rates and stronger bond strength, while flame spray may be preferred for lower-volume or field work. Process fit should be confirmed based on your specific spray gun model, power source, and coating specification. We recommend discussing your equipment setup with our team so we can verify compatibility before you order.

Pack Options and Handling

SPA2Z supplies Stainless 304 spray wire in 15 kg, 20 kg, and 25 kg spools, as well as coil packs for certain production environments. Spools are wound for consistent payoff and minimal tangling during continuous spraying. Proper storage in a dry environment is recommended to maintain wire surface condition and feed reliability.

Applications

Where this coating wire is commonly used.

Corrosion Protection Coatings

Applied to mild steel structures, tanks, and fabrications to provide a stainless steel surface layer that resists atmospheric and fresh water corrosion.

Dimensional Restoration

Used to rebuild worn or machined undersized stainless steel shafts, journals, and housings before final machining to specification.

Bond Coat Layers

Acts as a compatible intermediate layer in multi-coat thermal spray systems where a stainless steel base is required before applying a ceramic or cermet topcoat.

FAQ

Which wire diameter should I choose?
It depends on your spray gun and the job. Common diameters are 1.6 mm, 2.0 mm, 2.5 mm and 3.2 mm. Confirm the tip size on your gun, or send a photo of your old spool.
Will this wire work with my arc or flame spray gun?
Our coating wires are made for arc spray and flame spray systems. Confirm the diameter your gun and contact tips are set for.
Do you supply spool or bulk quantities?
Yes. Order a single spool or bulk. Choose Kg, Spool or Coil and enter the quantity in the quote form.
How do I get the price and delivery time for wire?
Choose diameter and quantity, then share your location. We reply within 24 hours with price and delivery time.
