AA 4820 FCAW Flux-Cored




AA 4820

 
CATEGORY 
TYPE 
High-alloyed tubular wire based on a 25% Chromium and 4% Nickel deposit for cladding and joining components against corrosion, high-heat and wear resistance. Developed for gas shielded arc welding.
APPLICATIONS 
- Cap layers for joining refractory Cr-Al-Si steels. - Cladding corrosion resistant overlays. - Cladding heat resistant overlays up to 1100ºC. - Cladding components in a sulphurous environment.
PROPERTIES 

Higher productivity, higher deposition rates and improved wetting properties compared to solid wires with comparable analysis. Excellent weld metal quality and X-ray soundness.
