• Price volatility in alloys

• Complex fabrication processes:The fabrication of duplex stainless steel is inherently complex due to the material's unique microstructure, which combines austenitic and ferritic phases. This dual-phase structure provides duplex stainless steel with exceptional strength and corrosion resistance, but it also presents challenges during fabrication. Processes such as welding, machining, and forming require careful control to maintain the integrity of the material's phases and avoid issues like phase imbalance, which can lead to reduced mechanical properties or compromised corrosion resistance. The complexity is further amplified by the need for specialized equipment and techniques tailored to the material's specific properties.

  Welding duplex stainless steel demands precise control of heat input and cooling rates to prevent the formation of undesirable microstructures like sigma phase, which can occur if the material is overheated or cooled too quickly. Techniques such as nitrogen-enhanced welding and the use of low-heat input welding processes are often employed to address these challenges. Additionally, post-weld heat treatments may be necessary to restore the optimal phase balance and mechanical properties. These requirements necessitate skilled personnel and advanced technology, making the welding process both intricate and costly.

  Machining and forming duplex stainless steel also require careful consideration of its physical properties. The material's high strength and hardness can lead to increased tool wear and the need for more aggressive cutting conditions compared to other stainless steels. Specialized tooling and machining techniques are often required to handle these challenges effectively. Moreover, the forming of duplex stainless steel, such as in the production of complex geometries, involves precise control of temperature and strain rates to avoid phase transformation that could affect the material's performance. Overall, the complexity of these fabrication processes underscores the need for advanced technology and expertise in the global duplex stainless steel market.
