FIELD: metallurgy.
SUBSTANCE: invention relates to the development of corrosion-resisting steel used as sheets or foil in soldered cellular panels, jacket articles and internal set articles working at temperature up to 450°C. Proposed corrosion-resisting steel comprises the following components, wt.-%: carbon, 0.005-0.03; chrome, 8.5-11; nickel, 10-16; molybdenum, 1.5-2.5; aluminum, 0.1-1.2; silicon, 0.2-1.3; calcium, 0.005-0.05; niobium, 0.1-0.3; cerium, 0.005-0.1; lanthanum, 0.003-0.05, and iron, the balance. Invention provides enhancing strength indices, impact tenacity and corrosion-resistance that allows decreasing weight of carrying cellular constructions and enhancing safety indices.
EFFECT: improved and valuable technical properties of steel.
