Filler Rod ER308L 3/32 1LB

The Filler Rod ER308L 3/32 1LB from EASTWOOD is an essential consumable for anyone performing stainless steel welding repairs on marine aluminum hulls, boat hardware, or saltwater-exposed equipment. After years on the water, you know that corrosion and fatigue are constant threats to vessel integrity—whether you're maintaining a fishing boat, restoring vintage marine hardware, or fabricating custom brackets and reinforcements.

This filler rod is engineered specifically for joining stainless steel components where strength, ductility, and corrosion resistance cannot be compromised in harsh marine environments. ER308L is a low-carbon stainless steel alloy that produces a weld deposit with excellent toughness and resistance to intergranular corrosion—critical properties for boat owners operating in saltwater. The 3/32-inch diameter strikes an ideal balance between ease of handling and deposition rate, allowing smooth, controlled welds on thin to medium-gauge marine components without excessive heat input that could warp delicate hull sections or fittings.

The 1-pound spool provides sufficient material for multiple repair jobs while remaining compact for onboard storage or workshop use. This rod is compatible with standard MIG welding equipment and delivers consistent arc performance across a wide range of amperage settings. Marine fabricators, boat repair shops, and serious anglers performing their own maintenance will find this filler rod indispensable for everything from repairs to custom fabrications.
