<p>A non-ageing low-alloy hot-rolled strip-form formable steel has a carbon content of between 0.02 and 0.10 wt.% and a thickness of between 0.5 and 5.0 mm. In order to bind N so as to achieve a non-ageing steel, while permitting direct entry of the steel to rolling from casting, the contents of titanium, nitrogen and sulphur in wt.% satisfy the conditions: Ti >/= 2.28 N Ti </= 3.43 N + 1.5 S and the steel is free from titanium carbide and niobium carbide.</p> |
