SFA 5.9: ER385

SFA 5.9: ER385

SFA 5.9: ER385 is a solid wire electrode for GMAW, suitable for welding steels of similar chemical composition 20Cr/25Ni/4.5Mo/1.5Cu type (AISI 904L type).SFA 5.9: ER385 has high resistance to corrosion in severe, non-oxidising environments, sulphuric, phosphoric and other inorganic and organic acids, also good resistance to corrosion in concentrated nitric acid. Due to the low carbon, high alloy content, allows excellent resistance to intergranular corrosion and stress corrosion cracking, high resistance to crevice and pitting corrosion when compared to standard grades AISI 304L and AISI 316L. Suitable for some offshore applications, including overlays on mild and low alloy steels
