welding-alloys.com 5 Welding consumables Welding Alloys manufactures advanced cored wires designed for hydropower applications, offering strong resistance to mechanical loading, cavitation and erosion. With extensive experience providing solutions to the industry, our consumables are produced with strict control of chemical composition and diffusible hydrogen (<4 ml/100g) to ensure consistent mechanical properties. Our consumables are designed for the repair and rebuilding of hydropower equipment, supporting longer service life and reliable operation. The range offers excellent weldability across several product families: Soft martensitic stainless steels Our CHROMECORE wires with 13% Cr, 4% Ni and Mo (410NiMo) are designed for joining or rebuilding CA6NM base materials. The range also includes an over-alloyed version with 16% Cr, 5% Ni and 1% Mo for improved pitting corrosion resistance. These wires are available as metal-cored, basicslag or rutile-slag options depending on the application. Austenitic stainless steels Our TETRA wire with 23% Cr and 12% Ni (309L) is designed for buffer layers, heterogeneous joining or corrosion-resistant cladding. Using cored wires in these applications provides higher deposition rates with lower heat input, helping to control the HAZ. Hardfacing solutions For surface protection, we offer CAVITALLOY, a work-hardening cored wire providing maximum cavitation and erosion resistance along with cobalt based STELLOY cored wires for severe wear conditions.
