Duplex Stainless Steel Plate

Our duplex innovation is unmatched in the industry and our offering covers a full palette of duplex stainless steels for use in diverse industries and applications. The high mechanical strength of duplex grades is a result of the duplex microstructure and the alloying with nitrogen. This high strength gives opportunities for reducing both weight and cost as a thinner material can be used. The low nickel content of the duplex grades makes them price stable.

Duplex 2205 is a two-phase, ferritic, austenitic 22% chromium, 3% molybdenum, 5 to 6% nickel alloyed stainless steel. It is the most widely used duplex stainless steel grade and is characterized by high yield strength, double that of the standard austenitic stainless steel grades. It also demonstrates good fatigue strength, as well as outstanding resistance to stress corrosion cracking, crevice, pitting, erosion, and general corrosion in severe environments.
