AK-ER410 13Cr Martensitic Stainless Steel Welding Wire.
A 13Cr martensitic stainless steel wire for welding corrosion-resistant components in hydropower and valve applications, with stable arc and clean bead profile.
Product Overview
AK-ER410 is a 13Cr martensitic stainless steel welding wire designed for use in corrosion-resistant applications such as hydropower stations and valves. It is suitable for welding base metals with similar composition and can also be used for surface surfacing.
The wire delivers a stable arc and produces a well-shaped weld bead, which supports consistent weld quality in both shop and field environments. It meets the EN ISO 14343-A:G 13, AWS A5.9 ER410, and GB/T 29713 S410 standards.
Application: It is used in corrosion- resistant occasions such as hydropower stations and valves. It is often used for welding alloys with similar compositions, and can also be used for surface surfacing.
Key Benefits
Stable Arc and Clean Bead.
The wire provides a stable arc during welding, resulting in a smooth, well-formed weld bead that reduces the need for post-weld grinding and cleaning.
Corrosion-Resistant Weld Metal
With a chromium content between 11.5% and 13.5%, the deposited metal offers good resistance to corrosion in moderate environments, suitable for hydropower and valve service.
Compatibility with Similar Alloys.
AK-ER410 is recommended for welding materials with similar composition, ensuring consistent metallurgical properties and performance in the final joint.
Surface Surfacing Capability
The wire can be used for surface surfacing applications where wear and corrosion resistance are required.
Where It Is Used
- Welding of corrosion-resistant components in hydropower stations.
- Valve body and stem welding.
- Repair and surfacing of 13Cr martensitic stainless steel parts.
- Fabrication of equipment exposed to moderate corrosive environments.
Who It Is For
- Welding consumable distributors supplying stainless steel welding wires.
- Fabricators working with 13Cr martensitic stainless steel in hydropower and valve systems.
- Maintenance teams performing repairs and surfacing on corrosion-resistant components.
Problems It Solves
- Achieving consistent weld quality when joining 13Cr martensitic stainless steel components with matching filler metal chemistry.
- Reducing post-weld rework caused by poor bead shape or unstable arc during welding.
- Providing a single wire solution for both base metal welding and surface surfacing in corrosion-resistant applications.

Use Guide
- Select wire diameter based on joint thickness and welding position; ensure the welding current is within the recommended range for the specific application.
- Clean the base metal surface from oil, grease, rust, and moisture before welding to prevent contamination and porosity.
- Store the wire in a dry environment and avoid exposure to humidity to maintain arc stability and weld quality.
- Follow recommended welding parameters for the specific application to achieve optimal mechanical properties and bead appearance.
How It Compares
AK-ER410 is a 13Cr martensitic stainless steel wire, suitable for welding similar alloys and surface surfacing. It differs from austenitic stainless steel wires like ER308L in that it forms a martensitic microstructure after welding, offering higher strength and moderate corrosion resistance. It is not intended for use in highly corrosive or cryogenic environments where higher chromium or nickel content is required.
