METHOD FOR PRODUCING A HOT PRESS CURED COMPONENT, USE OF A STEEL PRODUCT FOR PRODUCING A HOT PRESS CURED COMPONENT, AND HOT PRESS CURED COMPONENT.

摘要

The invention relates to a method, by means of which high-strength components protected against corrosive attack can be simply produced. To this end, the method comprises the following steps: a) providing a steel product generated at least in segments from a stainless steel having the following composition (indicated in % by weight) C: 0.010-1.200 %, P: up to 0.1 %, S: up to 0.1 %, Si: 0.10-1.5 %, Cr: 10.5-20.0 % and optionally one or more elements from the group "Mn, Mo, Ni, Cu, N, Ti, Nb, B, V, Al, Ca, As, Sn, Sb, Pb, Bi, H" at the proportion of Mn: 0.10-3.0 %, Mo: 0.05-2.50 %, Ni: 0.05-8.50 %, Cu: 0.050-3.00 %, N: 0.01-0.2 %, Ti: up to 0.02 %, Nb: up to 0.1 %, B: up to 0.1 %, V: up to 0.2 %, Al: 0.001-1.50 %, Ca: 0.0005-0.003 %, As: 0.003-0.015 %, Sn: 0.003-0.01 %, Sb: 0.002-0.01 %, Pb: up to 0.01 %, Bi: up to 0.01 %, H: up to 0.0025 %, remainder iron and unavoidable contaminants; b) heating the steel product through to an austenizing temperature above the Ac3 temperature of the stainless steel; c) hot press curing the heated steel product to form the component in a press tool; and d) cooling at least one segment of the component obtained at a cooling speed high enough that a hardened microstructure forms in the rapidly cooled segment.
