Description: AFM E2553-16 is primarily used to weld duplex stainless steels which contain
approximately 25 percent of chromium. Weld metal deposited by AFM E2553-16 has
ˇ°duplexˇ± microstructure consisting of an austenite-ferrite matrix. It combines
increased tensile strength with improved resistance to pitting corrosive attack
and to stress corrosion cracking.
