This European Standard specifies the technical delivery conditions for forgings for pressure purposes, made of weldable fine grain steels with high proof strength.
NOTE   Once this standard is published in the EU Official Journal (OJEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of Directive 2014/68/EU are satisfied, needs to be done. The series EN 10222-1 to EN 10222-5 is structured so that the data related to different materials is in the part allocated for that material. The presumption of conformity to the Essential Safety Requirements of Directive 2014/68/EU depends on both the text in part 1 and the data in part 2, 3, 4 or 5.
General information on technical delivery conditions is given in EN 10021.

This European Standard applies to steel castings for pressure containing parts. It includes materials
which are used for the manufacture of components, for pressure equipment.
This European Standard relates to castings characterised by their chemical composition (see Table 2)
and mechanical properties (see Tables 3 to 6).
In cases where castings are joined by welding by the founder, this European Standard applies.
In cases where castings are welded:
— to wrought products (plates, tubes, forgings), or
— by non founders,
this European Standard does not apply.
NOTE For this harmonised supporting standard for materials, presumption of conformity to the Essential
Requirements of the Directive is limited to technical data of the material in the standard and does not presume
adequacy of the material to specific equipment. Consequently the technical data stated in the material standard
should be assessed against the design requirements of the specific equipment to verify that the Essential

Consequently the technical data stated in the material standard should be assessed against the design requirements of the specific equipment to verify that the Essential Requirements of the Pressure Equipment Directive (PED) are satisfied.

ISO 4991:2015 covers steel castings for pressure containing parts. It includes materials which are used for the manufacture of components subject to pressure vessel codes and components not subject to codes. This International Standard relates to castings manufactured from unalloyed and alloyed steel grades (characterized by their chemical composition, Table 1, and mechanical properties, Tables 2, 3, 4 and 5). NOTE Annex D gives information on ISO grade designation and available UNS numbers which are similar to the ISO grade designation.

This European Standard specifies the technical delivery conditions for forgings for pressure purposes, made of weldable fine grain steels with high proof strength.
NOTE   Once this standard is published in the EU Official Journal (OJEU) under Directive 2014/68/EU, presumption of conformity to the Essential Safety Requirements (ESRs) of Directive 2014/68/EU is limited to technical data of materials in this standard and does not presume adequacy of the material to a specific item of equipment. Consequently, the assessment of the technical data stated in this material standard against the design requirements of this specific item of equipment to verify that the ESRs of Directive 2014/68/EU are satisfied, needs to be done. The series EN 10222-1 to EN 10222-5 is structured so that the data related to different materials is in the part allocated for that material. The presumption of conformity to the Essential Safety Requirements of Directive 2014/68/EU depends on both the text in part 1 and the data in part 2, 3, 4 or 5.
General information on technical delivery conditions is given in EN 10021.

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.

1.1 This part of ISO 9327 covers the technical delivery conditions for forgings (see note 1) and for rolled or forged bars for pressure purposes manufactured from the following internationally used steels (see note 2): a) non-alloy and alloy ferritic or martensitic steels with specified room temperature properties and supplementary requirements for elevated temperature properties covered in ISO 9327-2; b) nickel steels with specified low temperature properties covered in ISO 9327-3; c) weldable fine grain steels with high proof strength (room temperature, elevated temperature and low temperature grades) covered in ISO 9327-4; d) austenitic and austenitic-ferritic steels (room temperature and elevated temperature grades) covered in ISO 9327-5. NOTE 1 In accordance with ISO 6929 the term forgings covers here open die forgings including ring rolled products as well as closed die forgings. NOTE 2 Additional to the internationally used steels for pressure purposes covered in parts 2 to 5 of ISO 9327, there are other steels used regionally or nationally for the same application. These other steels shall not be precluded by this International Standard provided that they comply with the relevant International or National Standards for vessel constructions. NOTE 3 The following International Standards also apply for steel products for pressure purposes: ISO 9328 parts 1 to 5, ISO 9329 parts1 to 4, ISO 9330 parts 1 to 6, ISO 4978. 1.2 In special cases variations of the requirements of this International Standard or additions to them may form the subject of an agreement at the time of enquiry and order (see annex C). 1.3 In addition to the requirements of this International Standard the general technical delivery requirements in ISO 404 apply, unless otherwise indicated in the following.
