Hunan Mana announces high-performance DSS

Hunan Mana Materials announced a high-performance duplex stainless steel. Duplex Stainless Steel (DSS) is a multi-phase structure metal material composed of ferrite (α) and austenite (γ) in considerable volume fractions. It combines the advantages of ferritic stainless steel and austenitic stainless steel, with excellent corrosion resistance, high strength and good plasticity. Duplex stainless steel has been widely used in petrochemical, marine engineering and construction industry as an important engineering structural material.

Mana R&D engineers have carried out the alloying computer-aided design based on the composition characteristics of 2205, 2507 and other duplex stainless steels, analyzed the influence of various raw materials on the composition in detail, and determined the optimal material ratio. In addition, this kind of duplex stainless steel has high N content and narrow composition range.
