OVERVIEW

Premium Stainless Steel Welding with Bonarc ER316L

The Bonarc ER316L TIG Rod (3.2mm) is a high-performance austenitic stainless steel filler metal designed for the most demanding industrial applications. Packaged in a convenient 5kg tube, these rods are engineered to provide superior weld integrity when joining base metals of similar composition, such as AISI 316 and 316L. This product is an essential consumable for professionals in the chemical, petrochemical, and food processing industries where corrosion resistance is paramount.

Superior Corrosion Resistance

What sets the ER316L apart from standard stainless rods is the addition of Molybdenum (Mo). This alloying element significantly enhances the weld's resistance to pitting and crevice corrosion, particularly in chloride-containing environments like marine atmospheres or chemical processing plants. Furthermore, the "L" in ER316L stands for "Low Carbon." By limiting the carbon content to a maximum of 0.03%, this rod minimizes the risk of carbide precipitation during the welding process. This feature is critical for maintaining the corrosion resistance of the grain boundaries, ensuring the longevity of the weldment without the need for post-weld heat treatment.

Industrial Grade Reliability

Bonarc produces these rods to strict AWS standards, ensuring consistent chemistry and diameter control. The 3.2mm (1/8") diameter is robust enough for welding medium-to-thick sections of stainless steel plate and pipe, providing excellent deposition rates while maintaining arc stability. The rod flows smoothly, creating a clean, aesthetic bead that requires minimal post-weld cleaning. It is also suitable for welding steels stabilized with Titanium or Niobium, offering versatility across various fabrication projects.

Applications

This filler metal is the preferred choice for fabricating tanks, evaporators, heat exchangers, and piping systems that handle corrosive acids, salts, and high temperatures. Whether you are repairing existing infrastructure or fabricating new components, Bonarc ER316L delivers the mechanical properties and chemical resistance required for safety and durability.

FAQ

The main difference is the addition of Molybdenum in ER316L. This gives ER316L superior corrosion resistance, especially against chlorides and pitting, compared to ER308L. ER316L is used for 316 grades, while ER308L is for 304 grades.

For TIG welding with ER316L, 100% Argon is the standard shielding gas. It provides excellent arc stability and protects the weld pool from atmospheric contamination.

Yes, you can use ER316L to weld 304 stainless steel. It will provide a weld with higher corrosion resistance than the base metal. However, it is more expensive than the standard ER308L used for 304.

The 'L' stands for 'Low Carbon'. This indicates that the carbon content is restricted to a maximum of 0.03%, which helps prevent carbide precipitation and intergranular corrosion.

When TIG welding with stainless steel rods like the ER316L, you should use DCEN (Direct Current Electrode Negative), also known as Straight Polarity.

Yes, ER316L is excellent for marine environments due to its Molybdenum content, which provides resistance to salt water corrosion.

Store the rods in their original packaging in a cool, dry place. Avoid exposing them to moisture, grease, or shop dust to prevent contamination of the weld pool.

Amperage depends on material thickness and travel speed, but generally, a 3.2mm (1/8") stainless TIG rod is used in the range of 90 to 160 Amps.
