Nicrex E312
High alloy stainless electrode of unusual versatility, giving a ferritic-austenic duplex weld metal with an approximate ferrite content of FN 60. Resistant to stress corrosion attack and highly insensitive to dilution by melted parent metal. Good scaling resistance up to 1150 °C.Application: joining of HWT steels, surfacing rails, rolls, forging dies, hot work tools, dies for plastics, etc.
