Speciality Valve holds a prominent position as a premier Super Duplex Globe Valve Manufacturer in India. Our reach extends globally, serving clients in France, Australia, Mexico, and Turkey. Our Super Duplex Globe Valves, crafted from high-grade super duplex stainless steel, exemplify quality and reliability. Globe valves are linear motion valves used to regulate the flow of fluid in a pipeline. The valve's name comes from the shape of its body, which resembles a globe.

The super duplex stainless steel is a high-performance material that offers superior corrosion resistance, high strength, and improved toughness due to its balanced mixture of austenite and ferrite phases. They are majorly designed for applications where resistance to corrosion, high-pressure capabilities, and reliability are critical.

Super Duplex Stainless Steel:

Super duplex stainless steel is a type of stainless steel alloy characterized by its high chromium, molybdenum, and nitrogen content. It typically contains about 25% chromium, which enhances its corrosion resistance, especially in aggressive environments such as those containing chlorides. Additionally, it has high levels of molybdenum and nitrogen, which further improve its resistance to pitting, crevice corrosion, and stress corrosion cracking. Super duplex stainless steel also offers good mechanical properties, including high strength and toughness, making it suitable for demanding applications in industries such as oil and gas, chemical processing, and marine environments.

Difference Between Duplex and Super Duplex Stainless Steel:

Duplex stainless steel contains a balanced microstructure of austenite and ferrite phases, offering good corrosion resistance and high strength. Super duplex stainless steel contains a higher proportion of alloying elements such as chromium, molybdenum, and nitrogen, providing even greater corrosion resistance and mechanical properties compared to duplex stainless steel. Super duplex stainless steel is more expensive and typically reserved for applications where extreme corrosion resistance and strength are required, while duplex stainless steel is suitable for many general-purpose applications where a balance of corrosion resistance and cost-effectiveness is desired.
