COMPOSITION OF WELDING STRIP AND WIRE Russian patent published in 2004 - IPC

FIELD: metallurgy.

SUBSTANCE: invention relates to complex alloyed welding materials for anticorrosive surfacing of articles in nuclear power engineering, particularly for surfacing and welding of hydrocracking reactors and other petrochemical equipment and other important parts. Proposed welding strip or wire contains the following components, mass %: carbon 0.01-0.025; silicon 0.16-0.35; manganese 1.30-1.70; chromium 23.0-24.50; nickel 14.00-15.50; sulphur 0.001-0.010; phosphorous 0.001-0.015; aluminium 0.010-0.05; nitrogen 0.010-0.025; copper 0.01-0.08; lead 0.0005-0.001; arsenic 0.001-0.005; thin 0.001-0.005; antimony 0.001-0.005; cobalt 0.005-0.05; rare earths 0.05-0.10; ferrum - the rest. Coating, thus formed, features higher resistance to embrittlement at operating temperature up 350^oC under intensive neutron irradiation in contact with high parameter water.

EFFECT: improved operation reliability and safety, increased service life of reactor housing of nuclear plants of new generation.
