All You Need to Know About Stainless Steel Super Duplex Pipes

It is a combined mixture of austenite and ferrite in 50-50%, which offers improved steel grade strength. Super duplex steel carries a higher molybdenum and chromium content. Both of these elements offer outstanding corrosion resistance to the product.

Composition of Stainless Steel super duplex pipes

Various elements are present in Stainless Steel super duplex pipes, including 24% chromium, nickel, and 3% molybdenum. All these elements are known to increase intergranular and pitting corrosion resistance. Additionally, nitrogen offers structural hardening and increases strength values without impairing toughness. Stainless Steel super duplex pipes offer higher resistance in an environment containing pitting and stress corrosion cracking.

Benefits of Stainless-Steel super duplex pipes

Stainless Steel super duplex pipes require less cost as compared with ferritic and austenitic grades. The material shows outstanding tensile and yield strength. These two properties of material offer the best choice for companies. Super duplex pipes are available with a small thickness and prevent comptonization of quality and performance.

Here, Super duplex is a term that came into use in the year 1980 to represent the high performance and high alloying ability. Stainless steel super duplex contains high chromium, making these pipes resistant and suitable to work in acidic, chlorine containing, and caustic solutions. Such conditions are present in the chemical and petrochemical industries. Super duplex stainless steel acts as the best replacement for steel material.

Features of Stainless-Steel super duplex pipes

Stainless-Steel super duplex pipes show high strength, corrosion-resistant and hence super duplex pipes are useful in the marine and chemical industries. Also, these pipes work well in architecture and wire lines, lifting, and pulley equipment. These Stainless-Steel super duplex pipes show improved corrosion resistance as compared with duplex steel. The material shows good yield and tensile strength with outstanding toughness and ductility. Cracking corrosion and stress corrosion abilities of Stainless-Steel super duplex pipes make them useful in versatile industrial applications. These Stainless-Steel super duplex pipes are useful in offshore platforms, heat exchangers, and chemical processing plants. The mechanical properties of Super duplex stainless steel pipes consist of elongation, hardness, and proof stress.
