OVERVIEW

Premium Performance for Alloy 20 Welding

When your project involves the critical welding of Alloy 20 (Carpenter 20) stainless steel, you need a filler metal that guarantees both structural integrity and corrosion resistance. The Exocor Executive ER320LR TIG Rod (3.2mm) is engineered to meet these demands. Known for its 'Low Residual' chemistry, this rod solves the common headache of hot cracking often associated with welding high-nickel stainless alloys. By keeping impurities like sulfur and phosphorous low, Exocor ensures a smooth, defect-free weld bead that stands up to rigorous inspection.

Welders will appreciate the 'Executive' difference immediately. These rods are manufactured with a focus on surface quality, ensuring they feed smoothly through your hand and melt cleanly without excessive slag or inclusions. The 3.2mm (1/8") diameter is perfect for filling joints in heavier wall pipe or plate often found in petrochemical and pharmaceutical plants. Whether you are repairing a sulfuric acid tank or fabricating new process piping, this rod provides the puddle control and wetting action necessary for high-quality TIG welding.

Each 10 lb tube comes with flag-tagged or stamped rods to prevent mix-ups in the shop—a crucial feature when working with expensive exotic alloys. The niobium stabilization ensures that the corrosion resistance of your weld matches the base metal, protecting your work against intergranular attack long after the arc is extinguished. Choose Exocor ER320LR for a reliable, crack-resistant solution to your Alloy 20 welding challenges.

FAQ

ER320LR has 'Low Residuals' of carbon, silicon, phosphorus, and sulfur compared to standard ER320. This modification significantly reduces the tendency for micro-fissuring and hot cracking in the weld metal.

It is designed for welding Alloy 20 (UNS N08020), also known as Carpenter 20 or 20Cb-3, and similar austenitic stainless steels containing molybdenum and copper.

100% Argon is the standard shielding gas for TIG welding with this alloy to ensure a stable arc and clean weld deposit.

Niobium (also known as Columbium) is added as a stabilizer to prevent the formation of chromium carbides, thereby protecting the weld against intergranular corrosion.

Yes, ER320LR can be used to join Alloy 20 to other stainless steels or nickel alloys, provided the corrosion resistance requirements of the application are met.

The 3.2mm diameter is approximately equivalent to 1/8 inch.

Direct Current Electrode Negative (DCEN) is the standard polarity for TIG welding with solid stainless steel filler rods.
