1.1 This part of ISO 9327 applies to forgings and rolled or forged bars in thicknesses up to 50 mm manufactured

from the steels listed in Table 1 and to be delivered according to the specifications given in ISO 9327-1.

1.1 This part of ISO 9327 covers the following data:

a) in Table 1 the limits for

the chemical composition according to the cast analysis;

the tensile properties at room temperature;

the indications on the usual heat treatment condition at the time of delivery;

b) in Table 2 the permissible product analysis tolerances on the limiting values given for the cast analysis;

c) in Table 3 the minimum impact energy values.
