Duplex stainless steel is unique in that its metallographic structure is composed of approximately 50% austenite and 50% ferrite. This duplex structure gives it the advantages of both types of stainless steel: it has the good toughness and weldability of austenitic stainless steel, and the high strength and excellent resistance to stress corrosion cracking (SCC) of ferritic stainless steel. This "best of both worlds" feature makes it an excellent material choice for harsh corrosive environments.

In harsh offshore environments, 2205 duplex seamless steel pipes are at the heart of critical systems exposed to corrosive seawater and process fluids. They are widely used in seawater cooling systems, process piping, fire water systems, and structural parts. Its high strength allows for thinner walls, significantly reducing platform weight, a key design advantage. Its superior corrosion resistance ensures long service life in salt spray and high chloride environments.
For demanding applications such as offshore platforms, our quality control is uncompromising. SMLSCO implements a strict three-step inspection system: from incoming material composition verification, to dimensional and surface control during production, to 100% final inspection of each finished pipe. We implement a series of non-destructive tests including PMI chemical analysis, eddy current or hydrostatic flaw detection to ensure that our products fully comply with ASTM A789 standards, providing reliable products with complete quality records for critical applications.
