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