OVERVIEW

High-Performance Stainless Steel Welding Wire

The Bonarc ER308L .035" MIG Wire is a premium quality consumable designed for the welding of austenitic stainless steels. Engineered to meet AWS A5.9 ER308L specifications, this solid wire is formulated with a nominal composition of 18% Chromium and 8% Nickel. It is specifically developed to join base metals of similar composition, such as AISI 301, 302, 304, and 308. The "L" designation indicates a low carbon content (maximum 0.03%), which is critical for reducing the risk of carbide precipitation during the welding process. This feature significantly enhances the weld metal's resistance to intergranular corrosion without the need for post-weld heat treatment.

Industrial fabricators rely on Bonarc ER308L for its consistent chemical composition and excellent mechanical properties. The wire exhibits high tensile strength and ductility, ensuring durable and reliable joints in demanding environments. It is suitable for a wide range of applications, including chemical processing equipment, food and beverage machinery, and architectural structures where corrosion resistance is paramount. The wire surface is precision-treated to ensure smooth feeding through MIG gun liners and contact tips, reducing downtime associated with wire jamming or burn-back.

This 1kg (2.2lb) spool is packaged to maintain wire cleanliness and prevent contamination prior to use. It is compatible with standard MIG welding setups utilizing Direct Current Electrode Positive (DCEP) polarity. For optimal results, shielding gases such as Argon/CO2 mixtures or Helium/Argon/CO2 tri-mixes are recommended to achieve a stable spray or short-circuit transfer mode. Whether for maintenance, repair, or production fabrication, the Bonarc ER308L delivers professional-grade results.

FAQ

For MIG welding with ER308L, a mixture of Argon and CO2 (typically 98% Argon / 2% CO2) or a Tri-Mix (Helium/Argon/CO2) is recommended for the best arc stability and corrosion resistance.

The 'L' stands for Low Carbon. ER308L has a maximum carbon content of 0.03%, which reduces the risk of carbide precipitation and intergranular corrosion compared to standard ER308.

Yes, ER308L is the standard filler metal for welding 304 and 304L stainless steels.

This is a 1kg (approx. 2.2lb) spool, which typically has a 4-inch (100mm) diameter. This is the standard size for most spool guns and small portable MIG welders.

You should use DCEP (Direct Current Electrode Positive), also known as Reverse Polarity, for MIG welding with solid stainless wire.

No, this is a solid MIG wire. It requires an external shielding gas (like Argon/CO2 mix) to protect the weld pool.
