OVERVIEW

Reliable Stainless Welds with Exocor 308L

When your project demands a clean, professional finish on stainless steel, Exocor 308L is the wire you can trust. Designed specifically for welding the most common stainless grades like 304 and 304L, this filler metal helps you produce welds that not only look great but stand up to the elements. Whether you are fabricating kitchen equipment, repairing a brewery tank, or building custom automotive exhaust parts, the 308L alloy ensures your welds won't rust out prematurely due to carbide issues.

Welders appreciate Exocor 308L for its smooth feedability and stable arc. It wets out evenly, creating a flat bead profile that requires minimal grinding and finishing. This is a huge time-saver on stainless jobs where aesthetics are often just as important as structural integrity. The low carbon content means you don't have to worry as much about the heat affecting the corrosion resistance of the metal surrounding your weld, giving you peace of mind on critical jobs.

This wire is versatile enough for all-position welding when used with the right parameters and gas mix. It handles well in both short-circuit and spray transfer modes (depending on diameter and gas), giving you the flexibility to tackle thin sheet metal or thicker plate. Make sure to keep your base material clean—use a dedicated stainless steel wire brush and acetone to remove oils—to get the best results. With Exocor 308L, you get professional-grade consistency spool after spool.

FAQ

It is primarily designed for welding 304 and 304L stainless steels, but can also be used for 308, 321, and 347 grades.

The 'L' stands for Low Carbon (0.03% max). This reduces the risk of intergranular corrosion caused by carbide precipitation in the heat-affected zone.

For solid wire, a Tri-Mix (90% He, 7.5% Ar, 2.5% CO2) or an Argon/Oxygen mix (98% Ar, 2% O2) is common. For flux-cored, 100% CO2 or 75% Ar / 25% CO2 is often used depending on the specific wire type.

No, for joining mild steel to stainless steel, you should use a 309L filler metal to prevent cracking.

Generally, no. The low carbon content allows for excellent corrosion resistance in the as-welded condition.

Yes, 308L is the standard alloy for fabricating stainless steel equipment used in the food and beverage industry.

Store in a cool, dry place. If the package is opened, keep it in a cabinet with a heat source or desiccant to prevent moisture absorption.

The tensile strength is typically around 85,000 psi (590 MPa), depending on welding parameters and heat input.
