EX80SD2000000450M0 - ER80S-D2 .045 Low Alloy MIG Welding Wire - 33lb Spool

High-Strength Low-Alloy MIG Wire for Critical Applications

The Executive ER80S-D2 .045 MIG Wire is a premium quality, low-alloy solid welding wire designed for joining high-strength steels. Manufactured by Exocor under the Executive brand, this wire is formulated with approximately 0.50% Molybdenum and 1.90% Manganese. This specific chemical composition provides a significant boost in tensile strength and yield strength compared to standard carbon steel wires, meeting the AWS A5.28 classification for ER80S-D2.

This wire is engineered for applications requiring weld deposits with tensile strengths exceeding 80,000 psi. It is particularly effective for welding Carbon-Manganese and low-alloy steels such as ASTM A302, A533, and A414, commonly found in the fabrication of boilers, pressure vessels, and heavy structural components. The high manganese content serves a dual purpose: it enhances the mechanical strength of the weld metal and acts as a vigorous deoxidizer. This deoxidizing capability makes the ER80S-D2 extremely forgiving when welding over contaminants like mill scale, rust, and oil, reducing the risk of porosity and ensuring radiographic quality welds.

The Executive ER80S-D2 exhibits excellent impact toughness, maintaining ductility even in lower temperature environments. It operates effectively with both 100% CO2 and Argon/CO2 shielding gas mixtures. The 33lb spool is precision layer wound to prevent tangling and ensure smooth wire feeding, which is critical for automated or long-duration manual welding processes. Whether used for heavy equipment repair, pipe welding, or structural steel erection, this wire delivers consistent penetration, bead profile, and mechanical integrity.
