ER2553
AWS A5.9 ER2553
ISO 14343:2009: (22 9 3 N L)
Description：
ER2209 is used to weld 22% Cr/ 5% Ni duplex stainless steels. 2205 Duplex base material shows higher strength compared with standard austenitic stainless steels, such as 316L. This material possesses good general corrosion resistance in a wide range of environments, but also has high resistance to pitting attack in chloride environments, such as sea water
