Weld Star ER 316LSi Stainless Wire [1kg Spool]

The Weld Star ER 316LSi 1kg Mini-Spool is the professional's secret weapon for intricate stainless steel fabrication and repair. Specifically designed to fit D100 (100mm) spool hubs found on portable and hobbyist MIG welders, this high grade "Marine Grade" wire allows you to achieve industrial quality results on a small scale.

Featuring 2.5% Molybdenum and a Low Carbon (L) content, this wire offers maximum protection against pitting and intergranular corrosion in salt spray and acidic environments. The Silicon (Si) enhancement ensures a highly fluid weld pool, making it exceptionally easy to produce flat, smooth, and aesthetically perfect beads on thin-gauge materials. Whether you are repairing a boat rail, fabricating a custom stainless exhaust, or working on delicate food grade equipment, these 1kg reels provide the precision and reliability of Weld Star's industrial range in a compact, manageable format.
