Stainless Steel Welding Filler Wire, Thickness: 1 MM TO 4 MM

For welding 304 to itself, use a 308/308L filler metal that offers a matching chemistry. Additionally, 309/309L is recommended for welding 304 to carbon steel or for the barrier layer for overlays on carbon steel.The 316/316L types of stainless steels contain molybdenum (Mo) and are commonly used in more corrosive applications than the 304 type. Therefore, the filler metal needs to match the base material, providing the additional Mo for those corrosive conditions.Again, to ensure proper filler metal selection, verify the base material combinations and their in-service applications with the customer or design engineer.
