MEDIUM-CARBON, HIGH-ALLOY, WEAR-RESISTING, COLD-RESISTANT STRONG STEEL

摘要

FIELD: ferrous metallurgy, particularly wear-resisting, cold-resistance steel for manufacturing knives, teeth and bulldozer rippers operating under hydro-and abrasion wearable conditions. SUBSTANCE: claimed medium-carbon, high-alloy wear-resisting, cold-resistant strong steel comprises, wt %: carbon, 0.32; silicon, 0.7; manganese, 4.0; nickel, 2.0; copper, 3.0; chromium, 5.0; molybdenum, 0.03; rhenium, 1.0; nitrogen, 0.02; vanadium, 3.0; barium, 0.04; boron, 0.04; niobium, 2.0; titanium, 1.0; aluminium, 1.0; cobalt, 5.0; and iron, the balance. EFFECT: improved properties of the steel.
