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...).
This part of ISO 9327 covers the following data:
- 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;
- in Table 2 the permissible product analysis tolerances on the limiting values given for the cast analysis;
- in Table 3 the minimum impact energy values;
- in Table 4 the minimum elevated temperature proof strength values.
