Resumen

1.1 This part of ISO 9327 applies to forgings and rolled or forged bars in thicknesses up to 250 mm manufactured

from fine grain steels (see NOTE) given in Table 1 and to be delivered according to the specifications given in

ISO 9327-1.

The steels are classified into

room temperature grades (P...),

elevated temperature grades (PH...),

low temperature grades (PL...),

low and elevated temperature grades (PLH...).

NOTE Fine grain steels are here understood as steels with grain size 6 or finer according to the grain size charts in

ISO 643.

1.2 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;

d) in Table 4 the minimum elevated temperature proof strength values.
