Description
The ER420 MIG Wire 1.2mm 15kg spool is a high-performance welding wire specially engineered for stainless steel applications where strength, wear resistance, and corrosion protection are crucial. This wire is widely used in tool manufacturing, hardfacing, and components exposed to high impact or abrasive environments.
Crafted for welding high-chromium stainless steels, ER420 MIG Wire contains higher carbon content, resulting in welds with exceptional hardness. It’s ideal for overlaying surfaces such as pump shafts, valve seats, dies, and cutting edges. The resulting welds offer outstanding resistance to abrasion, corrosion, and thermal fatigue.
This 1.2mm wire is optimal for use with Argon/CO₂ shielding gas mixtures, providing stable arcs, low spatter, and smooth bead appearance. The 15kg spool size ensures minimal downtime during production or repair, making it suitable for industrial-scale projects.
Post-weld heat treatment is often recommended with ER420 to reduce brittleness and improve overall toughness, especially when working on parts that experience repeated mechanical stress or elevated temperatures.
