F Cr-Mo 23

AWS: SFA SFA 5.28 ER90S-G

F Cr-Mo 23 is a solid wire available in bright finish, gives smooth flow, stable arc and spatter free under optimum welding conditions. It gives radiographic quality weld deposit. Weld metal of having less impurities i.e. S, P will improve the impact property at sub-zero temperatures. It is suitable for welding creep-resisting steels of similar composition. It is especially applicable wherever prolonged heat treatment cycles are involved. It is ideal for welding P23/T23 material welding.
