1. Scope This standard specifies grade, dimension, shape, weight, allowable deviation, technical requirements, test methods, test rules, packaging, mark and quality certificate. This standard is applicable to the steel plate, steel strip, section steel and steel bar of the high strength low alloy structural steels which are with general structure or is used for the engineering. 2. Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this standard. For date reference, the subsequent amendments to (excluding amending error in the text) or revisions of, any of these publications do not apply. And parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. For undated references, its latest edition referred to applies.

Terms and Definitions 3.1 Thermomechanical rolling The ultimate deformation is a rolling procedure, which is carried out within a certain temperature range. This procedure makes the material obtain the special performance which is not obtained only through heat treatment. Note 1: If the temperature is increased to 580℃ after the rolling, the material strength value may be reduced. If it is necessary to increase the temperature to 580℃, it shall be supplied by the seller. Note 2: Thermomechanical rolling delivery state may contain accelerated cooling or accelerated cooling plus tempering (contain self tempering), but excludes direct quenching or quenching plus tempering. 3.2 Normalizing rolling The ultimate formation is a rolling procedure, which is carried out within a certain temperature range. This procedure makes the material obtain the performance which is equivalent to that after the normalizing.
