AK-ER80S-Ni1 Gas-Shielded Welding Wire for Low-Temperature Steel Applications.
A gas-shielded welding wire designed for 550 MPa minimum tensile strength deposits with excellent low-temperature impact toughness at -45°C, suitable for critical low-temperature service environments.
Product Overview
AK-ER80S-Ni1 is a gas-shielded welding wire for manual and automated welding of low-temperature steel structures. It delivers a deposited metal with tensile strength of at least 520 MPa and yield stress of at least 470 MPa, meeting the mechanical requirements for demanding low-temperature applications.
The wire is formulated to produce a stable arc, smooth bead profile, and good fluidity of molten metal, resulting in low spatter and consistent weld quality across all positions. It is suitable for use in industries requiring performance in extreme cold, including low-temperature containers, pipelines, machinery, and LPG storage tanks.
Application: It is suitable for industries such as low-temperature containers pipeli es, machinery, and LPG storage tanks, and can meet the requirements of -45°C low-temperature environment.
Key Benefits
High Strength and Toughness at -45°C.
The deposited metal achieves impact energy of at least 54 J at -45°C, ensuring reliable performance in cryogenic environments without brittle fracture.
Stable Arc and Smooth Weld Pool.
The wire provides a stable arc and excellent fluidity of molten metal, which results in a clean, uniform bead with minimal spatter and consistent weld shape.
Compliant with International Standards.
AK-ER80S-Ni1 is supplied to EN ISO 14341 A G 465 M 13 3Ni1 and AWS A5.28 ER80S-Ni1 classifications, ensuring compatibility with global welding specifications.
Versatile Positional Welding Performance.
Recommended parameters cover flat, horizontal, vertical, and overhead positions, enabling consistent results across all joint orientations.
Where It Is Used
- Low-temperature storage tanks and vessels including LPG and cryogenic containers.
- Pipelines and pressure systems operating in cold climates.
- Structural components in machinery and offshore equipment exposed to sub-zero temperatures.
- Fabrication and repair of steel structures requiring impact resistance at -45°C.
Who It Is For
- Welding consumable distributors serving low-temperature steel projects.
- Fabricators and EPC contractors working on cryogenic or cold-climate infrastructure.
- Maintenance teams responsible for inspection and repair of low-temperature storage systems.
Problems It Solves
- Achieving required impact toughness at -45°C in welded joints without compromising strength or process stability.
- Sourcing a single welding wire that meets both EN ISO 14341 and AWS A5.28 standards for low-temperature applications.
- Reducing weld defects such as spatter and poor bead shape during automated or manual welding in critical environments.

Use Guide
- Select diameter based on joint thickness and welding position. Use 2.5 mm for thin sections and vertical/overhead welds.
- Set welding current within the recommended range: 2.5 mm (50–120 A flat/horizontal, 50–120 A vertical/overhead), 3.2 mm (80–150 A flat/horizontal, 80–150 A vertical/overhead), 4.0 mm (170–550 A flat/horizontal).
- Ensure shielding gas is clean and dry; use argon-rich mixtures as specified in the welding procedure.
- Clean base metal surfaces of rust, oil, paint, and moisture before welding to avoid porosity and ensure full penetration.
How It Compares
AK-ER80S-Ni1 is designed for low-temperature service with high impact toughness at -45°C. Compared to ER80S-B2, which targets higher strength and creep resistance in elevated temperature service, AK-ER80S-Ni1 prioritizes toughness at low temperatures. For applications requiring even higher nickel content or specialized alloying, other Ni-containing wires may be considered, but AK-ER80S-Ni1 offers a balanced solution for -45°C environments.
