The report reviews steelmaking, steel design and processing and limitations to the wider use of higher strength structural steel plates and sections in Europe. The marketplace for these steels is also reviewed. Advances in steelmaking technology such as desulphurisation, inclusion shape control, vacuum degassing and continuous casting enable a high quality product to be manufactured. Their effect on mechanical properties and microstructure is reported. The development of normalised, controlled-rolled, accelerated-cooled and quenched and tempered steels with respect to alloy design and processing procedures is also presented. The property limitations of each type of steel grade relative to processing are discussed and commercially available grades within Europe are tabulated. The data presented shows that high strength steels can be welded according to documented procedures, with careful control. Fatigue performance and various methods of improving the life of high strength steel joints are discussed. Limitations to the wider use of high strength structural steel imposed by existing standards and codes are emphasised and proposals are made to improve this situation.
