5Kg - ER316LSi 0.8mm Stainless Steel MIG Welding Wire – Moly-Enhanced for Superior Corrosion Re...

ER316LSi is a solid stainless steel MIG wire formulated for the GMAW process, designed to weld austenitic stainless steels such as 316, 316L, and similar grades. The addition of molybdenum enhances pitting and corrosion resistance, especially in chloride-rich environments. The elevated silicon content improves arc stability, puddle fluidity, and bead appearance, making it ideal for both manual and automated welding applications.

This 0.8mm wire on a 5kg spool delivers consistent feed performance, low spatter, and excellent mechanical properties across a wide range of stainless steel fabrication tasks.
