Hardsurfacing Products/ Stainless Steel/Tubular WiresTubular WiresHobart FabTuf ® 960OverlayWith CO 2 shielding, FabTuf 960 is the right fillermetal when you need a high quality, uniformdeposit that’s porosity-free. It’s ideal for CO 2welding in hard surfacing applications wheremoderate impact strength and moderate abrasionresistance is required. It is also an excellent choicefor metal-to-metal wear resistance applications.During welding, the tubular steel sheath and metalpowders of the core fuse together to form alloysteel weld metal with almost no slag. You’ll get adeposition efficiency equal to that of solid weldingwires. FabTuf 960 can be used for out-of-positionwelding.Typical applications:• coal conveyors• conveyor bucket lips• dredge parts• extruder wormsTypical weld metal properties(Chem Pad):Carbon ........................ 0.70Manganese.................. 2.00Chromium ................... 8.00Silicon......................... 1.00Machinability: Possible by grindingFlame cut: NoHardness: 55-60 RCWear index: 35Type of current: DCEPAvailable diameter and recommendedoperating ranges:Dia.
