OVERVIEW

Smooth Feeding 316L Stainless Wire for Professional Results

When your project demands the best in rust resistance and weld quality, reach for the Bonarc ER316L .030" MIG Wire. This 5kg spool is the perfect size for shop fabrication, offering enough material for substantial jobs without the bulk of industrial drums. If you are welding 316 or 316L stainless steel—common in boat fittings, brewery tanks, and commercial kitchen equipment—this is the wire you need to match the base metal's durability.

What sets this wire apart is the "Moly" (Molybdenum) content. It acts like a shield against salt water and harsh chemicals, ensuring your welds don't become the weak link in the structure. Plus, the low carbon formula keeps your welds tough and crack-resistant, even if you can't heat treat the part afterwards. The .030" (0.8mm) diameter is versatile, allowing you to weld thin sheet metal with control or handle thicker sections with multiple passes.

Expect a smooth, stable arc with minimal spatter when running this wire with your tri-mix or Argon/CO2 gas. The bead lays down flat and shiny, reducing grinding time and making polishing easier. Whether you are repairing a prop shaft or building a custom stainless exhaust, Bonarc ER316L delivers the professional performance you rely on.

FAQ

For MIG welding stainless steel, a mixture of Argon with 1-2% Oxygen or 2-5% CO2 is recommended to ensure arc stability and good bead wetting.

Yes, ER316L can be used to weld 304 stainless steel and will provide excellent corrosion resistance, although ER308L is the standard match for 304.

The 'L' stands for 'Low Carbon'. This indicates a maximum carbon content of 0.03%, which prevents carbide precipitation and intergranular corrosion.

This wire is .030 inches (0.8mm) in diameter, suitable for a wide range of material thicknesses.

This is a solid MIG wire requiring an external shielding gas.

This is a 5kg (approx. 11lb) spool, typically a D200 size that fits most standard MIG welders.

Molybdenum increases the alloy's resistance to pitting and crevice corrosion, especially in chloride environments like saltwater.

Use DCEP (Direct Current Electrode Positive), also known as Reverse Polarity, for MIG welding with this wire.
