OK 61.86

Niobium stabilized stainless steel electrode for welding niobium or titanium stabilized steels of the 19Cr 10Ni-type. Specially designed for use in applications where heat treatment is required. OK 61.86 can be a bit sensitive for hot cracking, so issued welding procedures should be followed carefully. Despite the low ferrite content level, the maximum working temperature should be limited to maximum 400°C. It will not match the creep resistance of base materials that are designed to work at higher temperatures.
