ER2509
Alloy 2509 is a bare, corrosion resistant, super duplex rod for welding austenitic-ferritic stainless alloys of the 25% Cr, 7% Ni, 4% Mo, low C type. Alloy 2509 has high intergranular corrosion, pitting and stress corrosion resistance. The alloy is widely used in applications where corrosion resistance is of the utmost importance, such as the pulp & paper, offshore and gas industries.
