European specifications in this sector is given in Table 4.12. Thus, whereas
particular grades of structural steel are specified for use in bridges and
buildings, similar compositions for pressure vessels are also identified in other
specifications, e.g. BS EN 10028. The first reaction to this situation might well be
to suggest that this represents an unnecessary and confusing duplication but, in
fact, the two types of specification deal with the property data that are important to
the specific end use. Whereas both types of specification cover tensile and impact
properties at ambient and sub-zero temperatures, pressure vessel codes may also
specify the tensile and stress rupture properties at elevated temperatures.
