ES 312-17 is a high-alloyed electrode which deposits a ferritic-austenitic duplex weld metal with approx. 40% ferrite.
It is resistant to stress corrosion and is highly insensitive to dilution.
Good scaling resistance up to 1150°C. ES 312-17 is used for joining dissimilar steels, steels with reduced weldability and buffer layers prior to hardfacing.
Applications: rolls, forging dies, hot work tools, dies for plastics and so on.
