OVERVIEW

Professional Grade TIG Rod for Chromoly & High-Strength Steel

When your project demands more strength than a standard mild steel rod can provide, the Exocor ER80S-D2 TIG Rod is the professional's choice. This 3/32" filler metal is legendary among fabricators working with 4130 Chromoly tubing, making it a go-to consumable for motorsports, roll cage fabrication, and experimental aircraft frames. The "80S" in the name stands for a minimum tensile strength of 80,000 psi, giving you the confidence that your welds can handle extreme loads and stresses without failure.

What sets the ER80S-D2 apart is its specialized alloy blend. It contains Molybdenum, which boosts strength and hardness, and high levels of deoxidizers like Manganese and Silicon. For the welder, this translates to a puddle that wets out smoothly and fights off porosity, even if the metal isn't perfectly prepped. The 3/32" diameter is incredibly versatile, offering enough deposition for thicker wall tubing and plate while still being controllable at lower amperages for detail work. You'll notice a clean, fluid puddle that freezes predictably, allowing for that stack-of-dimes appearance that every TIG welder strives for.

This 10lb tube ensures you have plenty of material on hand for large projects or ongoing repair work. The 36-inch rods are stamped for easy identification, so you never mix up your filler metals. Whether you are repairing heavy equipment, building a custom chassis, or welding high-yield pipe, Exocor's ER80S-D2 delivers the performance, consistency, and strength required for critical welds. Pair it with 100% Argon shielding gas and a sharp thoriated or lanthanated tungsten for best results.

Why Choose ER80S-D2?

  • Superior Strength: Outperforms standard ER70S-2 and ER70S-6 in tensile and yield strength.
  • Chromoly Compatible: The preferred rod for welding 4130 and 4140 alloy steels in many applications.
  • Clean Welds: High deoxidizers help prevent pinholes and porosity in the weld bead.
  • Versatile Sizing: 3/32" diameter covers a wide range of material thicknesses from 1/8" up to 3/8" with multi-pass.

FAQ

ER80S-D2 contains Molybdenum and higher Manganese, providing higher tensile strength (80,000 psi min) and better high-temperature properties compared to the standard ER70S-2 mild steel rod.

Yes, ER80S-D2 is commonly used to weld 4130 Chromoly, especially for applications like roll cages and airframes where high strength and ductility are required. However, always consult the specific welding procedure specification (WPS) for your project.

100% Argon is the standard shielding gas for TIG welding with ER80S-D2 rods.

Preheat requirements depend on the base material thickness and carbon equivalent. For high-strength alloys like 4130, preheating is often recommended to prevent cracking, especially on thicker sections.

These rods have a diameter of 3/32 inches (approximately 2.4mm).

ER80S-D2 has high levels of deoxidizers (Manganese and Silicon) which help control porosity on slightly dirty or rusty steel, though cleaning the base metal is always best practice.

The weld metal typically exhibits a tensile strength of at least 80,000 psi (550 MPa) in the as-welded condition.

This product comes in a 10lb (approx. 4.54kg) protective tube.
