Description
The ER307 1.6mm TIG Wire 5kg is a stainless steel welding wire engineered for joining dissimilar metals, including mild steel to stainless steel. It’s ideal for applications where high toughness, crack resistance, and strength are needed. This makes it a reliable choice in industries such as construction, fabrication, mining, and transport where mixed-metal joints are common.
ER307 contains higher levels of manganese and nickel compared to typical stainless wires. These elements give it excellent crack resistance and increased strength. It’s especially effective in dynamic applications where the weld may experience mechanical stress or vibration. The low carbon content also reduces the risk of carbide precipitation, which improves corrosion resistance in the welded area.
With its 1.6mm diameter, this TIG wire provides smooth feeding, a stable arc, and easy handling during manual welding. It produces clean, consistent welds with minimal spatter, making post-weld cleanup quick and simple. The 5kg pack size is perfect for job shops and smaller fabrication projects that require precision without unnecessary waste.
Welders often choose ER307 TIG wire for railings, machine components, and structural supports where different types of steel must be joined with confidence. It performs best with DC+ current and is compatible with standard TIG welding equipment.
