PDF DownloadENiCrMo-4 Electrode Supplier / C276 Filler Metal / Manufacturer Direct
ENiCrMo-4 is a covered electrode classified under AWS A5.11 for SMAW welding. It is commonly used for welding Nickel Alloy C-276 (UNS N10276) and other Ni-Cr-Mo alloys where resistance to severe corrosion is required.
With high levels of nickel, molybdenum, chromium and tungsten, ENiCrMo-4 electrodes provide excellent resistance to pitting, crevice corrosion, stress corrosion cracking, and aggressive chemical environments. The electrode is particularly suitable for maintenance, repair, fabrication, and field welding of chemical processing and pollution-control equipment.
We supply ENiCrMo-4 welding electrodes for industrial and project applications, with available diameters, packaging, inspection documents, and technical support according to customer requirements.

Note: ENiCrMo-4 is the SMAW covered-electrode classification for C-276 nickel alloy weld metal. ERNiCrMo-4 is a separate filler metal classification used for wire and rod welding processes such as GTAW and GMAW.
| Element | C | Mn | Si | Cr | Ni | Mo | Fe | W | Co | V | P | S |
| Content (%) | ≤0.02 | ≤1.0 | ≤0.08 | 14.5–16.5 | 58.0–63.0 | 15.0–17.0 | 4.0–7.0 | 3.0–4.5 | ≤2.5 | ≤0.35 | ≤0.04 | ≤0.03 |
The combination of Cr, Mo and W provides strong resistance to localized corrosion, while the nickel-rich matrix maintains weld-metal stability in aggressive chemical environments.

Ø Excellent Corrosion Resistance: High chromium, molybdenum and tungsten contents provide strong resistance to pitting, crevice corrosion and aggressive chemical environments.
Ø Designed for C-276 Applications: ENiCrMo-4 is primarily used with Alloy C-276 / UNS N10276, making it a suitable choice for fabrication, maintenance and repair of corrosion-resistant equipment.
Ø Suitable for Severe Service: The nickel-based weld metal provides good resistance to stress corrosion cracking and localized corrosion in chloride-rich, acidic and mixed chemical environments.
Ø Suitable for SMAW & Field Repair: As a covered electrode, ENiCrMo-4 is convenient for manual welding, maintenance, field installation and repair, including applications where automated welding is impractical.
