OVERVIEW

Reliable Performance for Stainless Projects

When your stainless steel project demands the best protection against rust and corrosion, reach for Bonarc ER316L TIG rods. This 4.0mm (5/32") filler rod is the heavy-hitter for thicker stainless sections, delivering a smooth, stable arc and a clean bead that makes you look good. Whether you are repairing marine hardware, building food-grade tanks, or fabricating custom exhaust systems, this rod flows easily and wets out perfectly.

The 316L alloy is essentially the 'marine grade' upgrade to standard stainless rod. It handles salt and harsh chemicals much better than 308L. Plus, the low carbon formula means your welds stay strong and rust-free over time, even without heat treating them afterwards. The rods come in a sturdy 5kg reusable plastic tube that keeps your filler metal straight, clean, and dry in the shop or on the truck.

Why Welders Choose Bonarc:

  • Smooth Feeding: Consistent diameter and finish ensure the rod doesn't stick or drag in your hand.
  • Clean Welds: High-purity alloy reduces impurities, resulting in minimal slag islands and less post-weld cleaning.
  • Versatility: Works great on 316L, but can also be used on 304 stainless when higher corrosion resistance is desired.

FAQ

100% Argon is the standard shielding gas for TIG welding stainless steel with ER316L rods. It provides a stable arc and protects the weld pool from oxidation.

ER316L contains Molybdenum, which provides superior corrosion resistance, especially against chlorides (salt) and acids, compared to ER308L. ER308L is typically used for 304 stainless, while ER316L is used for 316 stainless.

TIG welding with stainless steel rods like ER316L is performed using DCEN (Direct Current Electrode Negative), also known as Straight Polarity.

Yes, ER316L can be used to weld 304 stainless steel. It will provide a weld with higher corrosion resistance than the base metal. However, ER308L is the cost-effective standard for 304.

These rods are typically cut to a standard length of 1000mm (approximately 39 inches), which is the industry standard for TIG filler metals.

For a 4.0mm (5/32") tungsten and filler rod, the amperage range is typically between 150A and 250A, depending on the material thickness and joint configuration.

Generally, no. The 'L' (Low Carbon) designation ensures resistance to intergranular corrosion without the need for post-weld annealing in most applications.

Yes, 316L stainless steel is widely used in food and pharmaceutical applications due to its excellent corrosion resistance and cleanability.
