FIELD: ferrous metallurgy.
SUBSTANCE: invention relates to investigation of steel composition used in making knives designated for cutting scrap metal. The claimed steel comprises the following components, wt.-%: carbon, 0.50-0.60; manganese, 0.40-0.60; silicon, 0.50-0.80; chrome, 1.0-1.30; tungsten, 2.20-2.70; vanadium, 0.12-0.20; nitrogen, 0.012-0.020; molybdenum, 0.35-0.50; aluminum, 0.015-0.035; iron, the balance. Steel can contain sulfur, o.020, not above; phosphorus, 0.020, not above, as impurities. Invention provides enhancing exploitation stability of scissors due to enhancing strength and viscosity of steel and resistance against fragile rupture.
EFFECT: improved, enhanced and valuable properties of steel.
