Duplex Steel Seamless Pipes & Tubes


S31803, S32205

Metal Udyog (India) is one of the leading entities in supplying and exporting Duplex Steel Seamless Pipes & tubes all across the globe. We are serving our clients with a wide range of Pipes & Tubes which are available in different shapes, dimensions, wall thickness, and specifications. We are offering high quality Pipes & Tubes at very reasonable rates. Duplex Steel Seamless Pipes & tubes possess tensile and yield strength is higher than conventional austenitic or ferritic grades of stainless steel. Duplex Steel S32205 exhibits excellent corrosion resistance, increased resistance to chloride attack, and good resistance to stress corrosion cracking. Duplex Steel S32205 Pipes & Tubes has good weldability and good formability. Duplex steels basically contain ferrite and austenitic microstructures. Duplex Steel S31803 Pipes & Tubes chemically composed of high chromium content and moderate nickel content along with the presence of Molybdenum. Duplex Steel S31803 has a very low nickel content that has a fully austenitic structure, thus producing the duplex microstructure.

Duplex Steel Seamless Pipes & tubes are widely used in heat exchangers, pressure vessel parts, chemical tanks, refineries, marine, petrochemicals, and pipes for the oil and gas industries, paper industry, compressor parts, and many more areas. Our Pipes & Tubes are highly durable in nature and thus serve for loge life applications. Good machinability is the remarkable feature of these Pipes & Tubes which enables them to work in a harsh environment with good flexibility. Moreover, these Pipes & Tubes come with a flawless finish and robust construction. Its embrittlement blemishes the high oxidation resistance property of Duplex Steel Seamless Pipes & Tubes. The embrittlement of the alloy can be modified by a full solution annealing treatment. The best suited heat treatment for this grade is Annealing, followed by rapid cooling. Grade S32205 exhibits higher resistance capacity to granular and intergranular corrosion. The Duplex Steel Seamless Pipes & tubes offer resistance to crevice corrosion, Chloride stress corrosion, and pitting. The co-efficient of thermal expansion for these Pipes & tubes is low hence the distortion and stresses are lesser than in austenite steel grade. Our offered Duplex Steel Pipes & Tubes has high mechanical strength and flexibility. Metal Udyog (India) uses High quality machinery and also the raw material is being tested before used in the production process. At Metal Udyog (India), all the offered range of Pipes & Tubes is fabricated by following national and international quality norms of the industry.
