FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, namely to use of titanium-free nickel-chromium-iron-molybdenum alloy with high resistance to pitting and crevice corrosion, as well as high yield point and strength. Used alloy contains, wt.%: C max. 0.02, S max. 0.01, N max. 0.03, Cr 20.0–23.0, Ni 39.0–44.0, Mn 0.4 - < 1.0, Si 0.1 - < 0.5, Mo > 4.0 - < 7.0, Nb max. 0.15, Cu > 1.5 - < 2.5, Al 0.05 - < 0.3, Co max. 0.5, B 0.001 - < 0.005, Mg 0.005 - < 0.015, if necessary: Ti max. 0.10, P max. 0.025, W max. 0.50, Fe and impurities associated with melting, - rest, which is obtained in form of alloyed alloy in form of wire, strip, rod or powder through melt phase, as filler material for welding in wet corrosion in oil and gas, as well as in chemical industry.

EFFECT: disclosed is the use of a titanium-free nickel-chromium-iron-molybdenum alloy.
