OK 61.50

OK 61.50 is a stainless steel electrode for welding of 19Cr 9 Ni austenitic stainless steels with a carbon content >0.04%. Especially designed for high temperature applications. The ferrite will transform to brittle phases when exposed to higher temperatures, but because the ferrite content is maximum FN 8, the amount of embrittlement which can occur in the weld metal is rather limited and controlled. The maximum temperature it can be exposed to is 800°C. It is not suitable for applications exposed to creep.
