Select 910-B91 is a low alloy steel electrode for flux cored arc welding with external gas shielding. It is designed for single and multiple pass welding of 9Cr-1Mo steels, in all positions. This electrode contains small additions of niobium, vanadium and nitrogen to improve long term creep properties. The recommended shielding gas is 75-80% Ar, balance CO2, with a suggested flow rate of 40- 50 cfh, and a minimum dew point of -40 deg F.
Features
Select 910-B91 is a premium, all position, flux cored electrode for joining 9Cr-1Mo steels.
Smooth and stable arc transfer, and the deposited weld beads are uniform with good tie-in
Offers increased deposition rates compared to covered and solid electrodes, has greater tolerance for rust and millscale, and eliminates lack of fusion defects associated with solid wire.
Applications
Select 910-B9 is used to weld 9Cr-1Mo creep resistant steels, such as A387 Gr 91 plate, A335 P91 and A369-FP91 piping, A199-T91, A200-T91 and A213-T91 tubing, A182-F91 forgings, as well as fittings and castings of similar composition.
Typical applications include power plant turbine casings, valves, headers and piping.
Caution
Protect yourself and others - read the safety data sheet prior to using this product.
