Lloyds LR AH 32 Heat Treatments

  • For plates and wide flats, grain refining practice Al or Al+Ti:
    t ≤ 20 mm, as-rolled (AR), furnace normalized (N), normalizing rolled (NR) and thermomechanically controlled rolling (TM);
    20 < t ≤ 150 mm, furnace normalized (N), normalizing rolled (NR) and thermomechanically controlled rolling (TM) (Material up to 35 mm thick may be supplied in the as-rolled condition provided that prior approval has been obtained from LR);

    For plates and wide flats, grain refining practice Nb or V or Al+(Nb or V) or Al+(Ti)+(Nb or V):
    t ≤ 12.5 mm, as-rolled (AR), furnace normalized (N), normalizing rolled (NR) and thermomechanically controlled rolling (TM);
    12.5 < t ≤ 150 mm, furnace normalized (N), normalizing rolled (NR) and thermomechanically controlled rolling (TM);

    For sections and bars, grain refining practice Al or Al+Ti:
    t ≤ 20 mm, as-rolled (AR), quench and tempered (QT), furnace normalized (N), normalizing rolled (NR) and thermomechanically controlled rolling (TM);
    20 < t ≤ 50 mm, furnace normalized (N), normalizing rolled (NR) and thermomechanically controlled rolling (TM) (Subject to the special approval of LR, sections may be supplied in the as-rolled condition provided satisfactory results are consistently obtained from CharpyV-notch impact tests);

    For sections and bars, grain refining practice Nb or V or Al+Nb or Al+V or Al+(Ti)+(Nb or V):
    t ≤ 12.5 mm, as-rolled (AR), quench and tempered (QT), furnace normalized (N), normalizing rolled (NR) and thermomechanically controlled rolling (TM);
    12.5 < t ≤ 50 mm, furnace normalized (N), normalizing rolled (NR) and thermomechanically controlled rolling (TM) (Subject to the special approval of LR, sections may be supplied in the as-rolled condition provided satisfactory results are consistently obtained from CharpyV-notch impact tests)
