EX70S2000000450T00 - Exocor ER70S-2 Mild Steel TIG Welding Rod 0.045" (10lb Tube)

Premium Triple Deoxidized Mild Steel TIG Wire

The Exocor ER70S-2 is a premium quality carbon steel cut-length TIG rod designed for critical welding applications where base metal cleanliness cannot be guaranteed. Distinguished by its "Triple Deoxidized" chemistry, this alloy contains specific additions of Zirconium (Zr), Titanium (Ti), and Aluminum (Al) alongside the standard Silicon and Manganese found in other mild steel wires. These added deoxidizers act as powerful scavenging agents, aggressively reacting with oxygen and nitrogen in the weld pool to prevent porosity and defects.

This metallurgical formulation makes ER70S-2 the preferred choice for welding on surfaces exhibiting rust, mill scale, oil, or primer. It is widely regarded as the industry standard for pipe welding, particularly for root passes where integrity is paramount. The wire produces deposits with high ductility and excellent impact toughness, meeting strict X-ray quality standards. It is suitable for welding ASTM A36, A285-C, A515-55, and A516-70 steels, as well as high-grade pipe materials like ASTM A106 and A53.

Fabricators in the power generation, petrochemical, and pressure vessel industries rely on ER70S-2 for its consistency and reliability. The 0.045-inch diameter offers precise control for thin-wall tubing and intricate detail work, while the 36-inch length fits standard storage and handling protocols. Packaged in a durable 10lb tube to protect against moisture and contamination.
