Abstract Stainless steels, especially AISI 304, are increasi ly used civil engineering materials in the last years because they have exc llent prop rtie . They are used f r many civil engineering stru tur s e.g. hemical, energy, bridges etc. The pre ented study br gs results of the observation of micro-structure and re ults on basic mechanical properties of AISI 304 ste l. This steel, s pplied in different profiles by different suppliers, can vary considerably, which must be taken into account when designing structures. © 20 23 The Authors. Published by Elsevier B.V.
