Is a Si, Cr, B alloyed flux cored electrode on Ni basis for build-up welding under shielding gas. The deposited weld metal corresponds in its properties to those of known cobalt hard alloys. This concerns in particular the hot hardness, the thermal shock resistance, the corrosion resistance as well as the wear resistance.
The welding wires are used for oil press screws, fittings, in chemical apparatus engineering, in the food industry, nuclear technology and paper industry.
The degree of hardness is 33 - 36 HRc.
