Strength and Toughness: Duplex stainless steel possesses high strength and toughness, making it suitable for applications that require good mechanical properties. It has a higher yield strength compared to austenitic stainless steel, which allows for thinner sections and reduced weight without compromising structural integrity.
Stress Corrosion Cracking Resistance: Duplex stainless steel has superior resistance to stress corrosion cracking, which is a common failure mode in many corrosive environments. This property is particularly beneficial in industries such as oil and gas, chemical processing, and marine applications.
High Temperature Resistance: Duplex stainless steel retains its mechanical properties and corrosion resistance at elevated temperatures, making it suitable for applications in high-temperature environments. It has a higher thermal expansion coefficient than austenitic stainless steel, reducing the risk of thermal fatigue.
Cost-Effectiveness: Duplex stainless steel offers a cost-effective solution compared to other high-performance alloys. Its superior strength and corrosion resistance allow for longer service life, reduced maintenance, and lower lifecycle costs.
Weldability: Duplex stainless steel exhibits good weldability, enabling ease of fabrication and joining. It can be welded using various techniques without significant loss of properties, making it suitable for complex structures and components.
