About Stainless 316 Spray Wire 4.0 mm

This thermal spray wire is manufactured from type 316 stainless steel, an austenitic chromium-nickel-molybdenum alloy. The addition of molybdenum enhances resistance to chlorides and acidic environments compared to standard 304 grades. When applied through arc or flame spray equipment, the wire forms a coating with good adhesion, low oxide content, and consistent mechanical properties.

The 4.0 mm diameter is a common size compatible with many industrial arc spray guns and heavy-duty flame spray torches. It offers a balance between feedability and deposition rate, making it suitable for both workshop and on-site coating jobs.

Coating Purpose and Performance

Stainless 316 coatings are primarily chosen for corrosion protection in aggressive environments. They resist attack from salt water, many industrial chemicals, and atmospheric corrosion. The coatings can also be used for rebuilding worn or machined parts where the original dimensions need to be restored with a corrosion-resistant layer.

Pack Options and Handling

SPA2Z offers this wire in standard spool sizes of 15 kg, 20 kg, and 25 kg, as well as coil pack configurations. Spools are wound to ensure consistent payout and minimal tangling during continuous spray operations. Coil packs are available for applications requiring longer uninterrupted run times or specific dereeling equipment. The exact pack type should be specified at the time of enquiry to match your machine's wire feed system.

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.
