FIELD: technological processes.
SUBSTANCE: invention relates to sheet steel provided with a coating providing cathodic protection with consumable anode. Disclosed is a sheet steel, having coating containing 1–40 wt% zinc, 0.01–0.4 wt% lanthanum, optionally up to 10 wt% magnesium, optionally up to 15 wt% silicon and optionally up to 0.3 wt% of the total amount of possible additional components with the rest consisting of aluminum and unavoidable impurities or residual elements. Also disclosed is a method of producing a steel part from the disclosed sheet steel and corresponding steel parts.
EFFECT: proposed sheet steel provided with coating has reinforced protection against corrosion and is capable of withstanding the propagation of microcracks in steel during heat treatment.
