Abstract (en)
[origin: EP0576107A1] The invention relates to the use of a dead-cast air-hardening steel consisting of (in % by weight): 0.15-0.30% of C 0.50 - 0.80% of Si 2.05-3.35% of Mn at most 0.03% of P at most 0.03% of S 0.50-1.00% of Cr at most 0.60% of Mo at most 0.05% of Al 0.01-0.05% of Ti 0.0015-0.0035% of B 0.002-0.015% of N as material for producing construction tubes for mechanically highly stressable construction elements, in particular for door reinforcements in motor vehicle construction, with the proviso that the following relationships are met: Ti (%): N (%) >/= 3.4% Mn (%) + Cr (%) + Mo (%) + Si (%) >/= 3.3%
