FIELD: chemical engineering. SUBSTANCE: composition has mass %: carbon 0.015-0.04; silicon 0.05-0.3; manganese 0.05-0.6; chrome 18.0- 28.0; nickel 7,2-14.0; nitrogen 0.05-0.3; tungsten 0.5-0.8; magnesium 0.05-0.1; lantana 0.05-0.15; iron - the rest. The ratio of nickel to chrome amount in any composition must be less or equal to 0.5 and larger or equal to 0.4. The nitrogen amount must be larger or equal to the silicon amount. EFFECT: improved corrosion resistance. 2 tbl
