Features:
- Most popular and versatile filler rod
- Perfect for mild steel, cast steel and chrome moly tubing
- Produces high quality welds even on dirty, rusty or oily surfaces
- X-Ray quality welds with no porosity
- Highest tensile strength of all plain carbon steel filler rods
- Creates a better bead with less grinding
ER70S-2 is the most popular and versatile rod used for welding 4130 chrome moly tubing as well as all mild steel and even cast steel. The main reason for its popularity is because it produces high quality welds, even when the metal is dirty, oily or even rusty. It provides x-ray quality welds with no porosity while having the highest tensile strength of all plan carbon steel filler rods. It is high in manganese and silicon and this chemistry increases the fluidity of the weld puddle, creating a better bead and less grinding.
