ER320LR00001250TL0 - ER320LR Stainless TIG Rod 1/8" (3.2mm) - 10lb Tube

Exocor ER320LR Stainless Steel TIG Rod - 3.2mm

Achieve superior weld integrity on Alloy 20 projects with Exocor ER320LR TIG Welding Rods. This 10lb tube of 3.2mm (1/8") cut lengths provides professional welders with a high-performance filler metal engineered to solve the cracking problems often associated with fully austenitic stainless steels. The ER320LR classification features a 'Low Residual' chemistry, significantly reducing trace elements like carbon, silicon, and sulfur to eliminate the risk of hot cracking and crater cracks.

Designed for the Gas Tungsten Arc Welding (GTAW) process, these rods offer excellent feedability and arc stability. The 3.2mm diameter allows for efficient deposition rates on medium-to-heavy gauge materials, making it a go-to choice for industrial fabrication and maintenance repair operations (MRO). The weld deposit offers exceptional resistance to general corrosion and pitting, particularly in environments containing sulfuric acid, phosphoric acid, and chlorides.

Whether you are repairing a chemical storage tank or fabricating new process piping, Exocor ER320LR ensures that the weld zone maintains the same mechanical and corrosion-resistant properties as the premium Alloy 20 base metal. Stored in a protective tube to prevent contamination, these rods are an essential inventory item for shops specializing in high-alloy stainless fabrication.
