101006 - ER316LSi Stainless MIG Wire - 0.035 in - 10 lb Spool

Premium ER316LSi Stainless Steel MIG Wire

The Central Wire ER316LSi Stainless Steel MIG Wire is a high-performance consumable designed for critical welding applications where corrosion resistance and bead appearance are paramount. This 10 lb spool of 0.035-inch wire is engineered with a modified chemical composition that sets it apart from standard 316L wires. The "Si" in the classification denotes a higher silicon content, which significantly improves the fluidity of the weld pool. This enhanced wetting action results in a smoother, flatter bead profile with excellent toe fusion, reducing the need for extensive post-weld grinding or finishing.

Constructed to meet AWS ER316LSi standards, this wire is primarily used for welding molybdenum-bearing austenitic stainless steels such as types 316 and 316L. The inclusion of molybdenum provides superior resistance to pitting and crevice corrosion, particularly in chloride-containing environments like marine atmospheres or chemical processing plants. Furthermore, the "L" designation indicates an extra-low carbon content (maximum 0.03%), which is crucial for preventing carbide precipitation during the welding process. This feature ensures the weldment retains its corrosion resistance even after exposure to elevated temperatures, protecting against intergranular corrosion.

This wire is an excellent choice for industries requiring high sanitary standards and durability, including food and beverage processing, pharmaceutical manufacturing, and petrochemical industries. The 10 lb spool size offers a perfect balance between portability and runtime, making it suitable for both shop fabrication and on-site repair work. It performs exceptionally well with shielding gas mixtures such as Argon/CO2 or Helium-based Tri-mixes, providing a stable arc and minimal spatter.

Key Applications:

• Food and beverage processing equipment
• Chemical storage tanks and piping
• Pharmaceutical manufacturing vessels
• Marine fittings and architectural structures
• Pulp and paper mill machinery
