OVERVIEW

High-Performance ER316LSi Stainless Steel MIG Wire

The ER316LSi .023" Stainless Steel MIG Wire is a premium welding consumable designed for the fabrication of critical stainless steel components. This wire complies with AWS A5.9 specifications and is formulated with a nominal composition of 19% chromium, 12% nickel, and 2.5% molybdenum. The "L" designation indicates a low carbon content (maximum 0.03%), which is essential for preventing intergranular corrosion and carbide precipitation during the welding process. This makes it particularly suitable for applications where the welded component will not undergo post-weld heat treatment.

Enhanced Metallurgy for Superior Wetting

The "Si" in ER316LSi denotes a higher silicon content (0.65% - 1.00%) compared to standard ER316L. This increased silicon level serves a dual purpose in industrial applications. Firstly, it acts as a deoxidizer, helping to remove impurities from the weld pool. Secondly, and most importantly for the operator, it significantly improves the fluidity and "wetting" action of the molten metal. This results in a smoother bead profile, better tie-in at the toes of the weld, and a reduction in the need for post-weld grinding or finishing. The presence of molybdenum provides enhanced resistance to pitting and crevice corrosion, particularly in chloride-bearing environments such as marine atmospheres or chemical processing plants.

Optimized for Thin Gauge Applications

With a diameter of 0.023 inches (0.6 mm), this wire is specifically engineered for welding thin gauge materials. The small diameter allows for operation at lower amperage ranges, providing precise control over heat input and minimizing distortion or burn-through on delicate sheet metal. Packaged on a standard 10 lb spool, it is compatible with a wide range of industrial wire feeders and portable MIG welding units.

Typical Industrial Applications

  • Chemical and Petrochemical Processing: Tanks, piping, and heat exchangers requiring resistance to acidic environments.
  • Food and Beverage Industry: Fabrication of sanitary equipment and storage vessels.
  • Marine Fabrication: Fittings and structural components exposed to salt spray.
  • Pharmaceutical Manufacturing: High-purity piping systems and reactors.

FAQ

For the best results with solid stainless MIG wire, a Tri-Mix gas (90% Helium, 7.5% Argon, 2.5% CO2) is often recommended for short-circuit transfer. Alternatively, a mix of 98% Argon and 2% Oxygen or a 98% Argon / 2% CO2 blend can be used for spray transfer or general applications.

The 'Si' stands for increased silicon content. ER316LSi has higher silicon (0.65-1.00%) than standard ER316L. This improves the wetting action of the weld puddle, resulting in a smoother bead profile and better tie-in at the toes of the weld.

Yes, you can use ER316LSi to weld 304 stainless steel. While ER308L is the standard filler for 304, using 316L is acceptable and provides slightly higher corrosion resistance. However, it is generally more expensive than 308L.

This solid MIG wire is designed to be used with Direct Current Electrode Positive (DCEP), also known as Reverse Polarity.

No, .023" is a very small diameter wire designed for thin gauge sheet metal (typically 24 gauge to 16 gauge). For thicker structural stainless steel, you would typically use .035" or .045" wire to ensure adequate deposition rates and penetration.

Yes, when welding with stainless steel wire, you should always use a Teflon or plastic liner in your MIG gun to prevent contamination from the steel liner and to reduce friction, ensuring smooth feeding.

Stainless steel wire should be stored in a clean, dry environment with low humidity. It should be kept in its original packaging until use to prevent contamination from dust, oil, or moisture, which can cause porosity in the weld.

The 'L' stands for 'Low Carbon'. This indicates that the carbon content is restricted to a maximum of 0.03%, which helps prevent sensitization and intergranular corrosion in the heat-affected zone.
