MIG Welding Wire – 316L Stainless Steel (Marine Grade) | 0.9mm | 8" Spool | 5kg
Product Overview
This 316L stainless steel MIG welding wire is purpose-built for marine and heavy-duty corrosion-resistant applications. With a 0.9mm diameter and wound on an 8-inch (200mm) spool containing 5kg of wire, it's an ideal choice for both professional fabricators and serious DIY welders working with stainless steel in demanding environments.
Key Features
- Grade: ER316LSi / 316L — low-carbon stainless steel wire formulated for superior resistance to pitting and corrosion, especially in chloride-rich (saltwater) environments
- Diameter: 0.9mm — versatile size suited for a wide range of material thicknesses, from light-gauge sheet to medium-section stainless plate
- Spool size: 8-inch (200mm), 5kg — extended run time between spool changes, reducing downtime on larger jobs
- Marine-grade formulation — molybdenum content enhances resistance to pitting and crevice corrosion caused by saltwater and marine atmospheres
- Low carbon content (L-grade) — minimizes carbide precipitation during welding, preserving corrosion resistance in and around the weld (heat-affected zone)
- Smooth, consistent feeding — precision-wound spool minimizes tangling and feed interruptions for clean, stable arcs
Common Applications
- Boat building, hulls, and marine fittings
- Shipbuilding and offshore structures
- Stainless steel piping and tanks exposed to saltwater or corrosive chemicals
- Food and beverage processing equipment
- Chemical processing plants
- General fabrication of 316/316L stainless steel components
Compatible Base Metals
Designed for welding 316 and 316L stainless steels, and compatible with joining 316L to 304/304L stainless where mixed-grade fabrication is required.
Why Choose 316L Over 304L Wire?
316L wire contains added molybdenum, giving it significantly better resistance to chloride pitting and crevice corrosion than standard 304L wire — making it the preferred choice anywhere the weldment will be exposed to saltwater, marine air, or aggressive chemical environments.
Recommended Shielding Gas
Typically used with a tri-mix (Argon/Helium/CO2) or 98% Argon/2% CO2 blend for optimal arc stability, bead appearance, and minimal spatter — check your welder/application specs for exact settings.
