OK Autrod 13.20SC (EB3R)
OK Autrod 13.20SC is designed to produce a 2-1/4% Cr and 1% Mo weld deposit to be used for welding process piping, heat exchangers, and pressure vessel fabrication. Used in combination with OK Flux 10.63 it meets step-cooling requirements.
Features
ESAB’s OK Autrod 13.20SC is a copper-coated low alloy submerged arc wire designed for the welding of creep-resistant steel of the 2-½% Cr-1% Mo type. When combined with OK Flux 10.63, OK Autrod 13.20SC produces a metalurgically clean weld which is capable of meeting X-factor of less than 15 and J-factor of less than 120. This combination fulfills the stringent requirements for toughness after step cooling treatment of the weld metal. OK Autrod 13.20SC can also be combined with OK Flux 10.62 for applications not requiring step cooling treatment.
OK Autrod 13.20SC is used for welding process piping, heat exchangers, and pressure vessel fabrication.
