Advantages of Duplex Stainless Steel
The unique feature of duplex stainless steel is that its metallographic structure is composed of approximately 50% austenite and 50% ferrite. This dual phase structure combines the advantages of two types of stainless steel: it has the good toughness and weldability of austenitic stainless steel, as well as the high strength and excellent stress corrosion cracking (SCC) resistance of ferritic stainless steel. This "win-win" characteristic enables duplex steel to provide a more reliable and economical solution than conventional austenitic stainless steel in harsh corrosive environments.
Material Properties of Duplex 2205
2205 is currently the most widely used duplex stainless steel grade. Its yield strength is more than twice that of conventional austenitic stainless steels such as 316L, which means that thinner wall thickness designs can be used in pressure applications, effectively reducing structural weight and saving costs. Its high chromium (Cr), molybdenum (Mo), and nitrogen (N) content brings extremely strong resistance to pitting corrosion and crevice corrosion (PREN ≥ 35). Especially outstanding is that it is almost immune to stress corrosion cracking (SCC) in chloride containing environments, solving a major problem for traditional stainless steel in marine and other environments.

2205 Duplex Tube Application in Marine Industry
2205 duplex steel pipe is an ideal choice for the marine industry. Its excellent resistance to seawater corrosion and high-strength characteristics make it widely used in various key systems. For example, process pipelines, seawater cooling systems, fire water systems, ballast water systems of offshore oil platforms, as well as structural components and pipelines on ships and chemical transport vessels. In seawater desalination (RO) equipment, it is also the core material of high-pressure pipelines and heat exchangers, which can ensure the long-term, stable, and safe operation of the equipment in harsh marine environments.
