ER70S-2 is multiple de-oxidized Plain Carbon Steel that has additions of 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-positon applications. The deposits have high ductility, excellent impact values and tensile strength.
ER70S-2 is often used on AISI 4130 tubing where lower tensile strengths are acceptable or where reinforcing gussets are used in the design.This wire is often used with TIG and Plasma for critical applications.
