Popis:	Creep deformation and rupture data over the temperature range 565–640 °C for the parent, Type IV, refined-heat affected zone, coarse grained-heat affected zone and weld materials, associated with a 0.5Cr–0.5Mo–0.25V ferritic steel parent material welded with a 2.25Cr–1Mo steel, has been collected and used to determine a constitutive equation parameter set. The constitutive equation parameter set has been generated for use in a future investigation to analyse a welded medium-bore branched vessel tested at 590 °C; and, also to permit extrapolation and interpolation over the temperature range 565–640 °C.
