DIPTIINOX® ER316LSi TIG Rod (AWS A5.9): Leading High-Silicon Low-Carbon Manufacturer & Exporter for Premium Weldability
Dipti Metal Industries is a Leading ER316LSi TIG Rod Manufacturer and High-Silicon Low-Carbon Welding Wire ER316LSi TIG Rod Exporter in Mumbai, India, specializing in high-performance AWS A5.9 ER316LSi GTAW filler metal under the DIPTIINOX® brand. This wire is the enhanced version of ER316L, retaining its low carbon content (0.03% max) for complete protection against intergranular corrosion (weld decay), but with a significantly increased Silicon (Si) level (0.65% - 1.00%). The added silicon dramatically improves weld pool fluidity, enhances arc stability, and results in a smooth, clean bead profile, thereby minimizing post-weld grinding. It affords the same high resistance to pitting corrosion as ER316L due to the Molybdenum. It is the preferred choice for both TIG and high-speed automated MIG applications demanding the best possible weld appearance and operability. We guarantee full conformance to AWS A5.9 for critical industrial applications globally.
DIPTIINOX® ER316LSi: Low-Carbon Corrosion Resistance with Enhanced Weldability
The AWS A5.9 ER316LSi Filler Metal offers the same core chemical characteristics and corrosion performance as ER316L—specifically the low carbon (0.03% max) for intergranular corrosion resistance and 2.0% - 3.0% Molybdenum for pitting resistance. The key differentiator is the significantly higher silicon content (0.65% - 1.00%). While silicon is typically a trace element, its elevation in the ER316LSi grade provides tangible benefits to the welding process, particularly improving the fluidity and 'wet-out' of the molten weld pool. This makes it an outstanding choice for automated processes like MIG (GMAW), where it dramatically improves wire feeding, arc stability, and bead shape. For TIG (GTAW), it results in a cleaner, smoother weld surface with minimal need for post-weld conditioning, affording the same strong assurance against intergranular corrosion as ER316L. It is available as TIG Rod (GTAW), and is highly recommended as MIG Wire (GMAW).

ER316LSi TIG Rod & Wire — Frequently Asked Questions
The 'Si' denotes a higher Silicon content (0.65% - 1.00%) compared to standard ER316L. Silicon is added primarily to increase the weld pool fluidity and improve the wetting action of the weld metal. This results in superior bead shape, cleaner weld surfaces, better arc stability, and less grinding, which is especially beneficial for automated welding processes (MIG/GMAW).
The primary corrosion resistance, including pitting resistance, is maintained by the Molybdenum and low carbon content (0.03% max), similar to ER316L. While high silicon can slightly affect the microstructure, the ER316LSi composition is balanced to retain excellent intergranular and pitting corrosion performance, matching the demands of 316L base metal.
ER316LSi is generally an upgrade for ER316L, particularly where weldability, bead appearance, and wire feeding (MIG) are critical. In TIG (GTAW), the added silicon improves the cleanliness and fluidity of the puddle. It provides all the corrosion benefits of 316L and is often chosen as the go-to low-carbon molybdenum filler metal.
Yes, ER316LSi is commonly manufactured in large coil form for SAW. The selection of the correct welding flux is critical for SAW, as the flux's chemistry significantly influences the final weld metal's silicon and carbon content, impacting the weld's mechanical and corrosion properties.
