DIPTIINOX® ER317L TIG Rod (AWS A5.9): Leading High-Molybdenum Low-Carbon Manufacturer & Exporter for Superior Acid Corrosion Resistance
Dipti Metal Industries is a Leading ER317L TIG Rod Manufacturer and High-Molybdenum Low-Carbon Welding Wire ER317L TIG Rod Exporter in Mumbai, India, specializing in high-performance AWS A5.9 ER317L GTAW filler metal under the DIPTIINOX® brand. This wire is the higher-Molybdenum, low-carbon version of 316L, featuring an elevated Molybdenum (Mo) content (3.0% - 4.0%). This makes the weld deposit significantly more resistant to pitting and crevice corrosion in aggressive chemical environments, such as those found in the Pulp & Paper and Chemical Processing industries. The low carbon content (0.03% max) ensures complete protection against intergranular corrosion (weld decay) in the as-welded condition. We guarantee full conformance to AWS A5.9 and ASME SFA A5.9 for all critical industrial applications globally.
DIPTIINOX® ER317L: High-Molybdenum Corrosion Resistance for Severe Environments
The AWS A5.9 ER317L Filler Metal is engineered for use with low-carbon molybdenum-bearing austenitic stainless steels such as 317L. It is defined by its core characteristic: a high Molybdenum (Mo) content in the range of 3.0% - 4.0%. This is a deliberate increase from standard 316L, which significantly improves the filler metal's resistance to localized attack, particularly pitting and crevice corrosion in environments containing aggressive chlorides and non-oxidizing acids. Coupled with the crucial low carbon content (0.03% max), which prevents carbide precipitation, the weld maintains exceptional integrity and assurance against weld decay even without post-weld solution annealing. ER317L is thus the specified choice for fabricating equipment where the corrosion risk is high and longevity is paramount.

Primary Applications for DIPTIINOX® ER317L TIG Rod & Wire
The ER317L filler metal is essential when joining 317L base metals or cladding 316L/304L to achieve a higher Molybdenum content in the weld, specifically for resistance to severe localized corrosion. Its key uses include:
Pulp and Paper Industry: Used extensively for welding bleaching towers, digesters, and other components exposed to corrosive chloride solutions.
Chemical Processing: Fabrication of vessels, heat exchangers, and piping systems handling medium to highly corrosive chemicals, particularly sulfuric and phosphoric acids.
Flue Gas Desulfurization (FGD) Systems: Welding scrubbers and components in power plants to resist condensate corrosion.
Textile and Dyeing Equipment: Components subject to aggressive organic and inorganic chemicals at elevated temperatures.
Pharmaceutical Equipment: Where extremely clean surfaces and high resistance to process media are required.

ER317L TIG Rod & Wire — Frequently Asked Questions
The primary benefit is the significantly higher Molybdenum (Mo) content, which is typically 3.0% to 4.0% in ER317L compared to 2.0% to 3.0% in ER316L. This increased Mo content provides superior resistance to pitting and crevice corrosion, especially in environments involving sulfuric or phosphoric acids, or chlorides.
The 'L' stands for 'Low Carbon,' meaning the carbon content is restricted to a maximum of 0.03%. This low carbon level is crucial for preventing intergranular corrosion (weld decay) that can occur in the Heat-Affected Zone (HAZ) of the weldment, particularly when the component is used in the as-welded condition.
ER317L is essential in industries where corrosive chemicals and high temperatures are prevalent. Key applications include: Pulp and Paper (bleaching plant components), Chemical Processing (sulfuric and phosphoric acid handling), Textile Equipment, and Flue Gas Desulfurization (FGD) systems.
Yes, ER317L can be used to weld 316L. Since it has a higher Molybdenum content, the resulting weld metal will have a higher corrosion resistance than the base metal, which is a desirable outcome often used in the chemical and paper industries where superior resistance in the weld zone is critical.
