Lloyds LR HSS Special Application 1 Heat Treatments

  • The plates shall be hardened by heating above the upper critical temperature, but not to more than 950°C, followed by water spray quenching. Subsequent quenching shall be in the range 600-675°C. Heat treatment records are to be supplied for each batch. Pickling or flame descaling is not permitted after heat treatment.
