Stainless 304 Coating Wire for Corrosion Protection

This 4.0 mm wire is manufactured from AISI 304 stainless steel, an austenitic grade known for good general corrosion resistance and oxidation resistance up to moderate temperatures. When sprayed, it produces a coating that resists attack from many organic chemicals, food products, and atmospheric conditions. The as-sprayed coating is machinable, allowing post-spray finishing to precise dimensions.

Typical spray processes include twin-wire electric arc spray and combustion flame spray. The 4.0 mm diameter is a standard size that balances high deposition rates with stable feeding in industrial spray systems. Process fit and parameter optimization should be confirmed with your equipment manufacturer; our team can assist with grade and diameter selection based on your application.

Pack Options and Availability

We supply this wire on 15 kg spools, 20 kg spools, 25 kg spools, or in coil packs. Spooled wire ensures consistent dereeling and minimal tangling during long spray runs. Coil packs are available for users with external dereeling setups. Standard packs are ready to ship; custom weights or packaging can be discussed on enquiry.
