Duplex stainless steels


Since their inception in 1935, European companies have introduced and actively refined duplex stainless steels. These alloys offer a host of advantages over equivalent austenitic grades, rendering them highly appealing. Notable benefits include heightened resistance to Stress Corrosion Cracking, superior mechanical properties, and reduced alloy costs.

These qualities translate into exceptional cost-to-performance ratios, especially in critical applications encompassing fields like oil and gas, chemical processing, pulp and paper production, water systems, desalination plants, pollution control apparatus, and chemical tankers. The growing emphasis on sustainability and Life Cycle Cost considerations has extended the adoption of duplex stainless steels into other domains, such as architecture, construction, and storage tanks. This broadening scope ensures the continued advancement of the entire duplex family.

Given the ongoing enhancements in their properties and the increasing accessibility of these materials, it is indisputable that duplex stainless steels will maintain their appeal as a solution for the future demands of mechanical engineering designers and users.
