Abstract:
UHC lightweight structural steel with improved scaling resistance, comprising the composition in % by weight C: 1 to 1.6, Al: 5 to 10, Cr: 0.5 to 3, Si: 0.1 to 2.8, the remainder iron and customary impurities accompanying steel, and a method for producing components hot-formed from this in air, wherein hot-forming temperatures of from 800 to 1050° C. are used, depending on the Si content.
