FIELD: metallurgy.
SUBSTANCE: annealed cold-rolled steel sheet is heated to a temperature of 890-950°C at a speed of at least 6°C/s, holded at said temperature for 4-5 minutes, then subjected to hot stamping and cooled in a stamp at a speed of 30-80°C/s to produce a product with temporary resistance of up to 2200 N/mm2.
EFFECT: production of complex shaped products and provision of high indicators of temporary resistance, yield strength, cold resistance, corrosion resistance, high plasticity and weldability.
