Lean duplex and ferritic stainless steel: The high-performance and cost-effective options for structural applications

With advancement in stainless steel manufacturing techniques, new types of cost-effective and high-performance stainless steel materials such as lean duplex and ferritic stainless steel have been increasingly used as structural members in construction. In recent years, several carbon steel bridges have been replaced by lean duplex stainless steel materials, which have been proven to be the most cost-effective solution due to the significant saving in maintenance. This seminar aims at introducing the latest advancements in construction materials that contribute to sustainable construction through extending service life without maintenance. It will cover the applications of stainless steel in construction and multi-criteria comparison of different types of steel; mechanical properties and structural behaviour under ambient and elevated temperatures; and new design methods in EC3 for key structural stainless steel components.
