ER70S-2 AWS A 5.18 CLASS ER 70S-2

ER70SD-2 is a multiple de-oxidized Plain Carbon Steel that includes Zirconium, Titanium, and Aluminum in addition to the high levels of Manganese and Silicon common to plain Carbon Steels of this group.

The ability of this wire to perform well over oily, dirty, or rusty surfaces is one of its key features.

ER70S-2 has a quick freezing weld pool with a somewhat tight molten range, which makes it an ideal choice for welding tubing, piping, and out-of-position applications.

The deposits have high ductility, excellent impact values and tensile strength.

ER70S02 is often used on AISI 4130 tubing where lower tensile strengths are acceptable or where reinforcing gussets are used in the design.

Tensile strength: 83,000 psi (specs call for 70,000 minimum).

Elongation is 25%.

This wire is often used with TIG and Plasma for critical applications.

The rod was fine but I ordered 5 lb's of .035 but received a mix of .045 and .035. O well I can use it up eventually and reorder .035 next time and check the packaging closer. Other than that good service and prices I will order again.

We apologize for the error on our behalf. We found the 2 lb discrepancy when we did inventory. The 2 lbs of 0.035" are on their way to you. Please keep the 0.045" for future projects.

Thank you and Good Welding,
Team Arc-Zone

Nice fluid puddle. Seems like good clean welding rod. Get really nice welds on 4130 chromolly tube.
