EX309L-125T - Exocor Executive ER309L Stainless TIG Rod 1/8" (3.2mm) - 10lb

Premium Grade ER309L TIG Filler Metal for Industrial Fabrication

The Exocor Executive ER309L TIG Rod (3.2mm / 1/8") represents the pinnacle of stainless steel filler metal quality, designed specifically for critical industrial applications requiring the joining of dissimilar metals. As part of the Executive series, these rods are manufactured with stringent quality controls to ensure consistent chemistry, diameter precision, and surface cleanliness. This attention to detail translates directly to improved productivity on the shop floor, reducing downtime associated with feed issues or weld defects.

ER309L is the essential "problem solver" in any fabrication shop's inventory. Its chemistry, featuring approximately 24% Chromium and 13% Nickel, provides a microstructure capable of absorbing dilution from mild steel base metals without cracking. This makes it the filler of choice for welding 300-series stainless steels to carbon or low-alloy steels. Additionally, the "L" designation indicates a low carbon content (maximum 0.03%), which is critical for preventing carbide precipitation during the welding process, thereby maintaining corrosion resistance in the heat-affected zone (HAZ).

Josef Gas recommends this product for petrochemical piping, power generation components, and heavy equipment repair where buffer layers are required before cladding. The rods are supplied in a durable 10lb tube, ensuring they remain straight and free from contaminants during storage and transport. Each rod is typically stamped or flagged, ensuring full traceability and preventing material mix-ups in multi-alloy environments.
