FIELD: ferrous metallurgy; low-alloyed steels designed for manufacture of heavy-duty parts of automobiles by stamping. SUBSTANCE: introduced additionally into steel which contains carbon, silicon, manganese, sulfur, phosphorus, aluminum, chromium, nickel, copper, calcium, niobium and nitrogen is titanium. EFFECT: higher liability to stamping, reduced in-plane anisotropy of mechanical properties, improved cold bending and elongation, reduced costs at metallurgical production. |
