Dipti Metal Industries is a Leading ER219 TIG Rod Manufacturer and High-Strength Stainless Steel Welding Wire Exporter in Mumbai, India, providing high-performance AWS A5.9 ER219 GTAW filler metal under the DIPTIINOX® brand. ER219 (UNS S21980) is a nitrogen-strengthened, high-manganese austenitic stainless steel wire designed for welding base metals like Nitronic 40 (21-6-9). This grade is renowned for offering approximately double the yield strength of common 300-series stainless steels while maintaining exceptional toughness at cryogenic temperatures and superior resistance to high-temperature oxidation. As a specialized Stainless Steel TIG Rod ER219 Supplier, we ensure our rods meet the rigorous demands of aerospace hydraulic systems and high-pressure chemical processing industries globally.
The AWS A5.9 ER219 TIG Rod represents a significant leap in austenitic stainless steel performance. By utilizing high manganese (8.0-10.0%) and nitrogen (0.15-0.40%), ER219 achieves mechanical properties that standard filler metals like ER308L simply cannot match. It is designed to weld 21Cr-6Ni-9Mn base metals, popularly known by the trade name **Nitronic 40**. The addition of nitrogen significantly increases the strength and resistance to pitting corrosion, while the manganese ensures a fully stable austenitic structure. This makes it a critical component for applications requiring high weight-to-strength ratios, such as in aerospace hydraulic tubing and marine hardware. Dipti Metal Industries specializes in the manufacturing of high-purity ER219 rods that offer excellent arc stability and puddle control for precision welding.

Properties are typical for as-welded conditions using 100% Argon. ER219 retains significant toughness at -196°C.
Our ER219 TIG Rod is produced with strict diameter tolerances for automatic or manual TIG applications. We recommend clean gas shielding to prevent nitrogen loss or contamination in the weld pool.
| Wire Diameter (mm) | Amps (DCSP) | Volts (V) | Shielding Gas | Gas Flow (CFH) |
|---|---|---|---|---|
| 1.6mm (1/16") | 70-110 | 12-14 | Argon 100% | 20-25 |
| 2.4mm (3/32") | 120-180 | 14-18 | Argon 100% | 25-30 |
| 3.2mm (1/8") | 170-240 | 17-21 | Argon 100% | 30-35 |
Note: For heavy sections, pre-heating is not required, but interpass temperatures should be controlled to below 150°C to maintain nitrogen solubility.

ER219 is the direct filler metal equivalent for Nitronic 40, an austenitic stainless steel alloy composed of 21% Chromium, 6% Nickel, and 9% Manganese. It is specifically formulated to provide high strength and weld integrity in high-stress environments.
ER219 provides approximately double the yield strength of standard 308L or 316L filler metals. While 308L is suitable for general-purpose 304 welding, ER219 is used where mechanical performance, cryogenic toughness, and resistance to oxidation at elevated temperatures are mission-critical.
Yes, ER219 is an industry standard in aerospace for welding high-pressure hydraulic tubing and engine exhaust components. Its ability to maintain high strength and corrosion resistance at a lower overall weight makes it ideal for flight systems.
For manual TIG (GTAW) welding with ER219, 100% Argon is the standard shielding gas. In some automated aerospace applications, specialized Argon/Helium or Argon/Nitrogen mixes may be used to control heat input and ensure nitrogen levels in the weld deposit remain optimal.
Specialized in high-nickel and nitrogen-strengthened alloys. We provide custom tagging, export-grade packaging, and full 3.1 certification for all aerospace and defense orders.
