Description:

SFC-91B3 is an all-positional flux cored wire designed for welding of 2-2.25%Cr-1%Mo low alloy steel. In conjunction with 100%CO2 shielding gas, it performs good weldability involved good bead appearance, less spatter and stable arc.

Applications :

It is suitable for welding Cr-Mo steel pipe and Cr-Mo steel with requirement of high creep resistance.

Note On Usage:

1. USe 100%CO2.

2. Proper preheat at 150-300C and PWHT at 620-720C.
