About ERNiCr-3 Welding Wire (Alloy 82)
ERNiCr-3 Welding Wire, widely known in the industry as Nickel Alloy 82 or Inconel Filler Metal 82, is a nickel-chromium-iron welding consumable. It is the standard choice for welding Inconel 600, Incoloy 800, and other high-temperature nickel-chromium alloys. Classified under AWS A5.14, this wire is engineered to produce welds with high strength and excellent corrosion resistance.
For fabricators in the USA, ERNiCr-3 is a critical material. It is specifically designed to handle dissimilar welding applications, such as joining stainless steels to nickel alloys or carbon steels to nickel alloys. Its versatility makes it a staple inventory item for heavy engineering workshops, power plants, and petrochemical refineries across states like Texas, Louisiana, and Pennsylvania.
Applications & Use Cases in the USA
The United States industrial sector relies heavily on materials that can withstand extreme environments. ERNiCr-3 Welding Wire for Inconel 600 plays a vital role in several key American industries:
- Nuclear Power Generation: Used for welding reactor components and heat exchangers where high-temperature strength and resistance to stress-corrosion cracking are mandatory.
- Petrochemical & Refining: Essential for fabricating furnace components, piping systems, and catalytic regenerators in the Gulf Coast region's massive refinery network.
- Cryogenic Storage: Ideal for welding 3% to 5% nickel steels used in the storage and transport of Liquefied Natural Gas (LNG).
- Dissimilar Metal Joining: The go-to filler for transition joints between ferritic steels and austenitic stainless steels in power plant boilers.
Features & Benefits of ERNiCr-3 Products
Our ERNiCr-3 welding wire offers superior performance characteristics that meet the rigorous demands of US engineering standards:
- High Temperature Strength: Maintains mechanical integrity and resists oxidation at elevated temperatures up to 2000°F (1093°C).
- Corrosion Resistance: Excellent resistance to a wide range of corrosive media, including organic and inorganic acids.
- Metallurgical Stability: The high manganese content (2.5-3.5%) helps prevent hot cracking during the welding process, ensuring defect-free joints.
- Versatility: Suitable for Gas Tungsten Arc Welding (GTAW/TIG), Gas Metal Arc Welding (GMAW/MIG), and Submerged Arc Welding (SAW).

Frequently Asked Questions (FAQ)
1. What base metals can I weld with ERNiCr-3?
ERNiCr-3 is primarily used for welding Inconel 600 and Incoloy 800. It is also excellent for dissimilar joints between stainless steels, carbon steels, and nickel alloys.
2. Is ERNiCr-3 the same as Inconel 82?
Yes, ERNiCr-3 is the AWS classification, while Inconel Filler Metal 82 is the common trade name for the same chemical composition.
3. Do you provide Mill Test Certificates for US shipments?
Absolutely. All our exports to the USA are accompanied by a Mill Test Certificate (MTC) in accordance with EN 10204 3.1, verifying the material's chemistry and mechanical properties.
4. What welding processes is this wire suitable for?
This wire is suitable for GTAW (TIG), GMAW (MIG), and SAW (Submerged Arc Welding) processes.
5. How do you package the wire for export to the USA?
We use high-quality, sea-worthy packaging. MIG wires are on plastic or basket spools, vacuum-packed. TIG rods are packed in plastic tubes. Everything is boxed and palletized to ensure it arrives in perfect condition.
6. Can you handle DDP shipments to the USA?
Yes, we can offer various Incoterms including FOB, CIF, and DDP (Delivered Duty Paid) to make the import process seamless for our US clients.
