ESAB OK Tigrod 316L Stainless Steel TIG Welding Rod – ER316L

ESAB OK Tigrod 316L – Stainless Steel TIG Welding Rod

The ESAB OK Tigrod 316L is a solid chromium-nickel-molybdenum stainless steel TIG filler rod designed for welding austenitic stainless steel alloys. It is classified as AWS A5.9 ER316L and EN ISO 14343-A W 19 12 3 L, making it suitable for professional TIG welding applications where good corrosion resistance and reliable weld-metal properties are required.

The low-carbon composition makes this filler rod particularly useful where there is a risk of intergranular corrosion. ESAB states that OK Tigrod 316L offers good general corrosion resistance, with particularly good resistance in acid and chlorinated environments.

Low-Carbon Cr-Ni-Mo Stainless Steel Composition

The ESAB OK Tigrod 316L is an austenitic stainless steel TIG filler material containing approximately 19% chromium, 12% nickel and 3% molybdenum, with low carbon content.

The typical wire composition published by ESAB is approximately 18.2% Cr, 12.0% Ni and 2.6% Mo, with approximately 0.01% carbon. This Cr-Ni-Mo formulation contributes to the corrosion resistance expected from 316L-type stainless steel weld metal.

ER316L TIG Filler Rod

The ESAB OK Tigrod 316L is classified under SFA/AWS A5.9 as ER316L. Its EN ISO classification is W 19 12 3 L, and its Werkstoffnummer is approximately 1.4430.

This makes the rod suitable for welding compatible austenitic stainless steel grades where an ER316L filler material is specified by the applicable welding procedure.

Excellent Corrosion Resistance

One of the principal advantages of the ESAB OK Tigrod 316L is its corrosion resistance. The molybdenum-containing composition provides particularly useful resistance in environments where stainless steel is exposed to corrosive conditions.

ESAB specifically identifies good general corrosion resistance and particularly good resistance against corrosion in acid and chlorinated environments.

This characteristic makes the filler rod suitable for applications where corrosion performance is an important consideration.

TIG Welding Applications

The ESAB OK Tigrod 316L is designed for TIG/GTAW welding and is supplied as a bare solid rod. ESAB specifies I1 shielding gas according to EN ISO 14175 and DC− current for the product.

The rod is suitable for professional stainless steel fabrication where controlled TIG welding and clean filler-metal addition are required.

Industrial Applications

ESAB identifies OK Tigrod 316L for applications across several industries, including:

• Chemical processing
• Food processing
• Shipbuilding
• Architectural structures
• Stainless steel fabrication
• Industrial maintenance
• General engineering
• Corrosion-resistant stainless steel fabrication

Its combination of low carbon content and Cr-Ni-Mo composition makes it appropriate for applications where stainless steel weld integrity and corrosion resistance are important.

Available Rod Sizes

The ESAB OK Tigrod 316L is available in several diameters and 1000 mm rod lengths. ESAB’s current product information lists 1.0 mm, 1.2 mm, 1.6 mm, 2.0 mm, 2.4 mm, 3.2 mm and 4.0 mm configurations, generally supplied in 5 kg packaging.

Actual availability and packaging should be selected according to the required diameter and your current stock.

Mechanical Properties

ESAB publishes typical as-welded mechanical properties for OK Tigrod 316L of approximately 470 MPa yield strength, 600 MPa tensile strength and 32% elongation. These are typical values rather than guaranteed values for every weld and should not replace the applicable welding procedure or material certificate.
