Stainless 420 Spray Wire 4.8 mm

Alloy Characteristics and Coating Purpose

Stainless 420 is a hardenable martensitic stainless steel. As a thermal spray wire, it produces coatings that offer a useful balance of hardness and corrosion resistance, making it suitable for applications such as dimensional restoration of shafts, rolls, and other machine elements, as well as general-purpose wear protection. The 4.8 mm diameter is a standard size for many high-deposition-rate arc spray systems.

Pack Options and Industrial Supply

We understand that production environments have different setup requirements. This wire is available in 15 kg spools, 20 kg spools, 25 kg spools, and coil packs. Selecting the right pack type helps reduce changeover time and ensures smooth feeding through your spray equipment. Please specify your preferred pack type and quantity when you enquire so we can provide an accurate quotation and lead time.

Process Compatibility and Selection Guidance

While Stainless 420 wire is widely used in both arc spray and combustion flame spray processes, the optimal process depends on your desired coating density, oxide content, and deposition efficiency. Our team can help you verify compatibility with your existing spray gun and controller setup. We recommend sharing your equipment model and base material details during your enquiry to ensure the wire meets your technical requirements.
