2 Materials
2.1 Structural stainless steels
2.1.1 General
(1) The provisions given in this Part 1.4 should be applied only to design using austenitic, austenitic-ferritic
and ferritic stainless steels.
(2) The nominal values of the material properties given in 2.1.2 should be used as characteristic values in
structural design calculations.
(3) For further information about material properties reference should be made to EN 10088.
(4) The design provisions specified in this Part 1.4 are applicable for material of nominal yield strength f
y
up to and including 480 N/mm .
NOTE: Rules for the use of work hardened material with f > 480 N/mm are given in Informative
y
Annex B.
(5) The higher strength of other materials (see 2.1.2 and Annex B) may be taken into account in the design
provided that doing so is justified by appropriate tests in accordance with Section 7.
2.1.2 Material properties for stainless steel
(1) In design calculations the values should be taken as follows, independent of the direction of rolling:
- yield strength f : the nominal stress (0,2% proof stress) specified in Table 2.1;
y
- ultimate tensile strength f : the nominal ultimate tensile strength specified in Table 2.1.
u
(2) The ductility requirements in EN 1993-1-1, clause 3.2.2 also apply to stainless steels. Steels conforming
with one of the steel grades listed in Table 2.1 should be accepted as satisfying these requirements.
(3) For structural hollow sections, the strength values given in Table 2.1 for the relevant product form of the
base material (cold-rolled strip, hot rolled strip or hot rolled plate) should be used.
(4) Higher strength values derived from cold working the base material may be used in design provided they
are verified by tests on coupons taken from the structural hollow section in accordance with Section 7.
(5) For cold worked material, the material tests given in the material certificate required according to EN
1090, should be in such a direction that the strength values used in design are independent of the direction of
rolling or stretching.
