PD 970:2005

PD 970:2005 specifies the technical purchase and supply requirements for wrought semi-finished products manufactured from a range of carbon, carbon manganese, low alloy, free-cutting, case-hardening and through hardened steels for the special applications of blooms, billets, slabs, bars, rods, flats and wide flats. NB: These wrought steels may be supplied in the hot-formed condition or as thermally treated black bar. Cold finished bar may be subjected to pre- or post-thermal treatment. PD 970:2005 also provides information on steel grades that are in regular use in the UK but have no equivalents set out in the new European Standards. It is also important to note that certain aspects of the requirements for steelmaking, deoxidation and grain size have been revised to reflect modern technology. PD 970:2005 supersedes PD 970:2001 which is withdrawn.
