ISO 9328-5:2018 pdf free.Steel flat products for pressure purposes一Technical delivery conditions
This document specifies the requirements for flat products for pressure equipment, made of thermomechanically rolled weldable fine grain steels as specified in Tables A.1 and B.1. The steels are not suitable for hot forming.
Until now, no sufficient data for the standardization of the elevated temperature properties of these steels are available. If their use at such temperatures is intended, the conditions for this are specially agreed upon between the interested parties.
The requirements and definitions of ISO 9328-1 also apply to this document.
NOTE 1 Fine grain steels are understood to be steels with a ferritic grain size of 6 or finer when tested in accordance with ISO 643.
NOTE 2 This document offers the possibility of specifying products in accordance with European design codes and ASME-type design codes.
The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

A number of options are specified in this document. These are listed below under a) to g). Additionally,the relevant options of ISO 9328-1 apply. If the purchaser does not indicate a wish to implement any of these options at the time of enquiry and order, the products shall be supplied in accordance with the basic specification (see ISO 9328-1):
a) carbon-equivalent value (see 6.3.3);
b) specification of an impact energy of 40J (see Note to 6.4 and Table A.4);
c) decreased minimum Altotal content (see Table B.1, footnote b);
d) increased maximum carbon content for the grade PT550ML1 (see Table B.1, footnote 9);
e) increased maximum silicon content for the grade PT550M (see Table B.1, footnote d);
f) other test requirements for the impact test (see Table B.4, footnote b);
g) tests on simulated heat-treated samples (see 6.7.2).ISO 9328-5 pdf download.
