The steel according to the invention consists of 0.12-0.20% by weight of carbon, 0.15-0.37% by weight of silicon, 0.3-0.8% by weight of manganese, 1.6-2.7% by weight of chromium, 0.8-2.0% by weight of nickel, 0.5-1.0% by weight of molybdenum, 0.05-0.15% by weight of vanadium, 0.002-0.08% by weight of cerium, 0.01-0.10% by weight of copper, 0.0005-0.009% by weight of antimony, 0.0005-0.009% by weight of tin, 0.001-0.02% by weight of sulphur, 0.002-0.02% by weight of phosphorus, 96.246-92.862% by weight of iron. The steel exhibits improved resistance against neutron radiation. At 300.degree. C. and neutron fluence of 1.10.sup.20 neutr./cm.sup.2, the transition embrittlement temperature increases by no more than 50.degree. C. The steel is designed for application in structural members having a wall thickness of up to 650 mm and has ultimate strength .sigma..sub.B at 350.degree. C. of at least 55 kgf/mm.sup.2. The steel does not require immediate temper after welding.

The apparatus comprises a cooled mould mounted on a bottom plate, a roof mounted on the mould, non-consumable electrodes connected to a power source and introduced into the melting chamber of the mould through sealed apertures in the roof, and a liquid metal pouring system incorporating a metal conduit with a funnel mounted in an aperture in the roof and an inclined chute positioned above the metal conduit funnel. The roof is provided with a gas exhaust pipe and with input funnels for feeding slag and alloying admixtures. The junction between the roof and the mould is sealed. The non-consumable electrodes are arranged around the circumference of the melting chamber for vertical movement, whereas the inclined chute is adapted to move in the horizontal plane. The enclosed melting chamber makes it possible to reduce heat losses and to maintain a controlled atmosphere within the mould.
