AK-ER430 Ferritic Stainless Steel Welding Wire for Corrosion-Resistant Applications.
A 17Cr ferritic stainless steel wire with stable arc, low spatter, and good bead appearance for welding heat- and corrosion-resistant Cr17 stainless steel.
Product Overview
AK-ER430 is a 17Cr ferritic stainless steel welding wire designed for manual and automatic gas metal arc welding of nitric acid-resistant and heat-resistant Cr17 stainless steel. The wire delivers a stable arc, minimal spatter, and a smooth, attractive weld bead profile.
It meets the EN ISO 14343-A:G Z 18 L Nb and AWS A5.9 ER430 classifications, and is also compliant with GB/T 29713 S430. The chemical composition is tailored to provide adequate corrosion resistance and mechanical strength in service conditions involving moderate heat and corrosive environments.
Application: Used for welding nitric acid corrosion-resistant, heat- resistant Cr17 st ainless steel, comm- only used in golf head welding.
Key Benefits
Stable Arc and Low Spatter.
The wire produces a consistent arc during welding, reducing spatter and improving weld quality, especially in automated or semi-automated processes.
Smooth and Aesthetic Bead.
The weld metal forms a clean, well-shaped bead with minimal surface irregularities, reducing the need for post-weld finishing.
Suitable for Cr17 Stainless Steel.
Specifically formulated for welding Cr17 stainless steel, which is commonly used in applications requiring resistance to nitric acid and elevated temperatures.
Compliant with International Standards.
Supplied to EN ISO 14343-A:G Z 18 L Nb, AWS A5.9 ER430, and GB/T 29713 S430, ensuring compatibility with global welding specifications.
Where It Is Used
- Welding of nitric acid-resistant Cr17 stainless steel components.
- Heat-resistant applications involving moderate temperature exposure.
- Golf head fabrication where corrosion resistance and appearance are important.
- General-purpose welding of ferritic stainless steel in industrial and structural applications.
Who It Is For
- Welding consumable distributors supplying ferritic stainless steel wires.
- Fabricators working with Cr17 stainless steel in chemical or food processing equipment.
- Golf equipment manufacturers requiring consistent, clean welds on head components.
- Maintenance teams repairing stainless steel parts exposed to mild corrosive environments.
Problems It Solves
- Achieving consistent weld quality on Cr17 stainless steel with a wire that maintains arc stability and minimizes spatter.
- Meeting corrosion resistance requirements in nitric acid environments without over-specifying filler metal.
- Reducing post-weld cleaning and finishing time due to a smooth, attractive bead profile.

Use Guide
- Select wire diameter based on joint thickness and welding position; ensure the welding current and voltage are within the recommended range for the process.
- Clean the base metal surface from oil, grease, rust, and scale before welding to avoid contamination and porosity.
- Use shielding gas as specified in the welding procedure, typically argon or argon-rich mixtures for GMAW.
- Store the wire in a dry environment and avoid exposure to moisture; re-dry if exposed to humid conditions before use.
How It Compares
AK-ER430 is a ferritic stainless steel wire suitable for Cr17 stainless steel, differing from austenitic wires like ER308L in that it has lower nickel content and no austenite stabilizers. It offers good resistance to nitric acid and moderate heat but is not suitable for welding dissimilar metals or applications requiring high ductility. Compared to ER304, it has lower toughness and is not used in cryogenic service. For higher corrosion resistance or weldability in thick sections, an austenitic filler may be preferred.
