AK-ENiCrFe-1 Nickel-Based Electrode for Heat and Corrosion-Resistant Welding.
A low-hydrogen, nickel-based covered electrode designed for welding nickel alloys and dissimilar steels requiring high resistance to heat and corrosion.
Product Overview
AK-ENiCrFe-1 is a nickel-based alloy electrode with a low-hydrogen coating, classified under EN ISO 14172-E Ni 6062, AWS A5.11, ENiCrFe-1, GB/T 13814, and ENi60662. The deposited metal has a chemical composition code of NiCr15Fe8Nb, which contributes to good plasticity and crack resistance in the weld zone.
The electrode is suitable for DC reverse polarity welding and can be used in all positions, making it adaptable for complex joint geometries in industrial fabrication and repair applications.
Application: Mainly used for welding nickel-based alloys and dissimilar steels that require heat and corrosion resistance.
Key Benefits
Good Plasticity and Crack Resistance.
The NiCr15Fe8Nb composition of the deposited metal ensures high plasticity and resistance to cracking, especially in high-stress or high-temperature environments.
Low-Hydrogen Coating
The low-hydrogen coating reduces the risk of hydrogen-induced cracking, which is critical when welding materials sensitive to embrittlement.
All-Position Welding Capability
Designed for use in flat, horizontal, vertical, and overhead positions, allowing consistent weld quality across different joint orientations.
Compatibility with Nickel Alloys and Dissimilar Steels.
Specifically formulated for welding nickel-based alloys and dissimilar steels where heat and corrosion resistance are required.
Where It Is Used
- Welding of nickel-based alloys in high-temperature and corrosive environments.
- Joining dissimilar steels requiring heat and corrosion resistance.
- Repair and maintenance of components exposed to thermal cycling and chemical attack.
- Fabrication of equipment in petrochemical, power generation, and chemical processing industries.
Who It Is For
- Welding consumable distributors supplying specialty electrodes for high-performance applications.
- Fabricators working with nickel alloys and dissimilar metal joints.
- Maintenance teams handling repairs in heat- and corrosion-prone systems.
Problems It Solves
- Achieving crack-free welds in nickel-based alloys and dissimilar steels where thermal stress and environmental exposure are high.
- Reducing the risk of hydrogen-induced cracking in critical welds through the use of a low-hydrogen coating.
- Providing a single electrode solution for all-position welding of high-performance materials without switching consumables.

How It Compares
AK-ENiCrFe-1 is a nickel-based electrode with a low-hydrogen coating, suitable for high-temperature and corrosive environments. It differs from standard mild steel electrodes like E6013 in composition and application. Unlike basic-coated electrodes used for low-hydrogen requirements in carbon steels, AK-ENiCrFe-1 is specifically designed for nickel alloys and dissimilar joints. It is not intended for general structural welding but for specialized applications where heat and corrosion resistance are critical.
