RK-70S-2

(Copper coated solid wire suitable for root pass in pipe welding and carbon steel welding)

DESCRIPTION AND APPLICATIONS: RK-70S-2 is a versatile triple de-oxidized carbon steel GTAW (TIG)/GMAW (MIG) wire with micro alloying elements like Zirconium, Titanium and Aluminum in addition to high levels of Manganese and Silicon. The ability of this wire to perform well over oily, dirty, or rusty surfaces is one of the key features of this product. It has a quick freezing weld pool with a 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. It 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.
