The advantages of Duplex Stainless Steels
Corrosion Resistance: Duplex stainless steel has excellent corrosion resistance due to its high chromium and molybdenum content. It is particularly resistant to stress corrosion cracking and pitting, which makes it suitable for use in harsh environments.
Strength: Duplex stainless steel is much stronger than conventional austenitic stainless steels, which allows for thinner and lighter constructions without sacrificing durability.
Toughness: Duplex stainless steel has a high toughness, which means it is resistant to brittle fracture and impact. This property makes it suitable for use in cryogenic applications.
Cost-effectiveness: Although duplex stainless steel is more expensive than conventional austenitic stainless steels, its superior properties can lead to cost savings in the long run by reducing maintenance and downtime.
Versatility: Duplex stainless steel can be used in a wide range of applications, including chemical processing, oil and gas, marine, and pulp and paper industries. It is also used in construction and architecture due to its aesthetic appeal.
