Abstract (en)

[origin: EP0753595A2] The use of a steel alloy of compsn. (wt. %): 0.18-0.3 C; 0.1-0.5 Si, 1.1-1.8 Mn, max. 0.025 P, max 0.025 S, 0.02-0.05 Ti, 0.0005-0.005 B, 0.01-0.05 Al, balance Fe plus usual melting impurities for tubes used in the production of stabilisers for vehicles, esp. torsion bars is claimed. Also claimed are: (i) the stabilisers made from the alloy; (ii) a process for producing stabilisers from drawn or welded tubes comprising normal annealing the tubes, producing the stabilisers; and water quenching; (iii) a process for producing bent stabilisers from non-hardened tubes comprising bending at above the Ac3 point followed by quenching; and (iv) a further process for producing bent stabilisers from tubes comprising hardening the tubes and then bending.
