Abstract: A high-manganese, non-magnetic steel having excellent weldability and machinability and suitable for use in the structural parts of electrical equipment or nuclear fusion equipment consisting essentially of (% by weight):______________________________________ carbon 0.55-0.80 silicon 0.1-1.2 manganese 10.0-14.5 nickel 0.3-3.0 chromium 0.5-3.6 nitrogen 0.01-0.2 ______________________________________balance iron and inevitable impurities. The steel may further contain at least one element of 0.01 to 1.0% of molybdenum, 0.01 to 0.5% of vanadium, 0.01 to 0.5% of niobium, 0.005 to 0.5% of titanium, 0.01 to 1.0% of zirconium, 0.0007 to 0.005% of calcium, 0.01 to 0.15% of sulfur, 0.03 to 0.2% of selenium, 0.03 to 0.2% of lead, and 0.01 to 0.8% of tin.

Abstract: The present invention relates to a coated welding electrode containing at least 0.5% of Cr based on the total weight of the welding electrode and comprising a metal core and a coating flux composition. In this welding electrode, the content of Na and K components in the coating flux calculated as (Na.sub.2 O + K.sub.2 O) is reduced below 1% based on the total weight of the coating flux composition, whereby amounts of fumes generated at the welding step, especially the amount of toxic soluble Cr, are suppressed and minimized.
