FIELD: metallurgy.
SUBSTANCE: invention relates to steel, which can be used to manufacture parts of machines operating under shock loads. Steel contains 0.005–0.01 % of carbon, 0.05–0.1 wt% of silicon, 0.1–0.3 wt% of manganese, 20.0–24.0 wt% of chromium, 0.8–1.2 wt% of aluminum, 0.3–0.4 wt% of molybdenum, 0.1–0.3 wt% of zirconium, 0.1–0.3 wt% of titanium, 3.5–4.5 wt% of nickel, the rest being iron.
EFFECT: increase of crack resistance of steel is ensured.
