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.
