36、rained steels steels with fine grain structure with an equivalent index of ferritic grain size 6 Note 1 to entry: For the determination of grain sizes, see EN ISO 643. 3.2 thermomechanical rolling rolling process in which the final deformation is carried out in a certain temperature range leading to
37、 a material condition with certain properties which cannot be achieved or repeated by heat treatment alone Note 1 to entry: Hot forming or post weld heat treatment at a temperature above 580 C may lower the strength values and for this reason is better not performed. Flame straightening can be appli
38、ed in accordance with CEN/TR 10347. For grades S900MC and S960MC, subsequent heating at temperature above 400 C is not recommended. Note 2 to entry: Thermomechanical rolling can include processes with an increasing cooling rate with or without tempering including self-tempering but excluding direct
39、quenching and quenching and tempering. Note 3 to entry: In some publications, the word TMCP (Thermomechanical Control Process) is also used. 3.3 normalised rolled rolling process in which the final deformation is carried out in a certain temperature range leading to a material condition equivalent t
40、o that obtained after normalising so that the specified values of the mechanical properties are retained even after normalising Note 1 to entry: In international publications for both the normalising rolling, as well as the thermomechanical rolling, the expression “controlled rolling“ may be found.
