Grade 50 plates over 21/2 inches in nominal thickness that fail to meet the minimum mechanical requirements after normalizing,may be quenched-and-tempered by heating to a temperature between 1500oF(815oC) and 1700oF(925oC) to produce an austenitic structure,holding a sufficient time to attain uniform heat throughout the material,quenching in a suitable medium,and tempering in the range from 1100oF to 1300oF (595oC to 705oC).
