Actual mechanical properties depend on electrode specification, welding procedure, testing conditions, and product batch.

Ø Excellent Corrosion Resistance: ENiCrMo-3 provides strong resistance to general corrosion, pitting, crevice corrosion, and chloride-containing environments.

Ø 625-Type Weld Metal: Its Ni-Cr-Mo-Nb composition is designed for applications involving Inconel 625 and similar nickel-base alloys.

Ø Suitable for Dissimilar Welding: The electrode is widely considered for selected joints between nickel alloys, stainless steels, carbon or low-alloy steels, and other demanding material combinations.

Ø Ideal for Field & Repair Welding: The SMAW electrode format is convenient for maintenance, repair, construction sites, and locations where TIG or MIG wire-feeding equipment is less practical.

Ø High Strength and Ductility: ENiCrMo-3 provides a combination of high tensile strength and ductility for demanding industrial service conditions.

Base Material	Typical Use
Inconel 625 / UNS N06625	Matching-alloy welding
Nickel-base Alloys	Nickel alloy fabrication and repair
9% Nickel Steel	LNG and cryogenic applications
5% Nickel Steel	Low-temperature applications
254 SMO / UNS S31254	Corrosion-resistant welding
Stainless Steels	Dissimilar-metal welding
Carbon / Low-Alloy Steels	Selected dissimilar-metal welding

Note: Final filler metal selection should be based on the base materials, service conditions, WPS/PQR and project requirements.

ENiCrMo-3 covered electrodes are used in demanding industrial applications where manual welding and corrosion-resistant nickel alloy weld metal are required.

• Offshore & Marine— offshore structures, marine equipment, seawater-exposed components and field repairs
• Oil & Gas— piping, valves, pressure equipment and corrosion-resistant repairs
• Chemical Processing— process piping, vessels, heat exchangers and corrosive-service equipment
• LNG & Cryogenic— 9% nickel steel and low-temperature equipment
• Power & Heavy Industry— high-alloy components, pressure equipment and maintenance
• Maintenance & Repair— localized repair, fabrication and field welding

ENiCrMo-3 and ERNiCrMo-3 are both associated with Inconel 625 nickel weld metal, but they are designed for different welding processes and product forms.
