FIELD: metallurgy.
SUBSTANCE: steel contains carbon, silicon, manganese, chromium, nickel, molybdenum, vanadium, niobium, copper, sulphur, phosphor and iron, at following component ratio, wt %: carbon 0.38-0.43, silicon 0.50-0.80, manganese 0.30-0.50, chromium 1.20-1.50, nickel 0.90-1.20, molybdenum 0.75-0.85, vanadium 0.18-0.28, niobium 0.02-0.05, copper ≤ 0.30, sulphur ≤ 0.01, phosphor ≤ 0.01, the rest is iron.
EFFECT: steel of satisfactory welding capacity for the thickness of up to 20 mm, enhanced durability, high bullet-proof characteristic combined with reduced tendency to armour fragmentation under effect of modern weapons.
