Duplex stainless steels are a family of stainless steels. These are called duplex (or austenitic-ferritic) grades because their metallurgical structure consists of two phases, austenite (face-centered cubic lattice) and ferrite (body centered cubic lattice) in roughly equal proportions.
Mar 7, 2024 · Duplex Stainless Steels are a specific group of engineering stainless steel materials consisting of the austenitic and ferritic phases in roughly equal proportions in the microstructure. They are widely popular because of their good corrosion resistance, high strength, and ease of fabrication.
Duplex stainless steels are materials that benefit from the properties of both austenitic stainless steels and ferritic stainless steels, as they are made of approximately 50% austenites and 50% ferrites.
Duplex stainless steels are a type of stainless steel that combine the beneficial properties of austenitic and ferritic stainless steels. The name "duplex" originates from the dual-phase microstructure of these materials, comprised of approximately equal parts austenite and ferrite.
What is Duplex Stainless Steel? Duplex stainless steels get their name from their two-phase microstructure. While exact ratios vary by grade, most duplex steels have a structure that is roughly 50-percent austenite and 50-percent ferrite.
Oct 5, 2023 · Duplex steel plates are flat, broad sheets of material that find applications in structural and industrial projects. Their high strength and corrosion resistance make them valuable for constructing pressure vessels, storage tanks, and various structural components.
Feb 3, 2023 · Duplex stainless steel is a type of stainless steel that has a dual microstructure made up of both austenite and ferrite phases. This combination provides the material with higher strength, greater corrosion resistance, and improved weldability compared to other forms of stainless steel.
May 18, 2005 · Duplex stainless steels are extremely corrosion resistant, work hardenable alloys. Their microstructures have both austenite and ferrite phases and show properties of both types of stainless steels. The properties, applications and fabrication details are provided for duplex stainless steels.
Outokumpu duplex stainless steel grades offer an excellent combination of strength and corrosion resistance, allowing you to significantly reduce material thickness and cost in a host of applications.
Jan 17, 2023 · Duplex stainless steel consists of a balanced mix of two distinct phases, austenite and ferrite. It combines the superior strength of ferritic and the corrosion resistance of austenitic. Its higher chromium and molybdenum content make it more resistant to pitting and crevice corrosion in harsh environments. The Composition.
