Duplex Steel Valve Manufacturer in India
Specialityvalve is the best Duplex steel valve manufacturer in India. A duplex steel valve is a type of industrial valve made from a special kind of steel known as “duplex stainless steel.” This steel is called “duplex” because it combines the properties of two different types of stainless steel: austenitic and ferritic stainless steels.
Austenitic stainless steel is corrosion-resistant and provides good strength at high temperatures, while ferritic stainless steel offers excellent durability and resistance to stress corrosion cracking. By blending these two types of stainless steel, a duplex steel valve achieves a unique balance of strength and corrosion resistance. These valves are used in various industries, such as oil and gas, chemical processing, and marine applications, where it needs to handle corrosive or aggressive fluids while keeping its foundation intact. Its distinctive properties make it suitable for challenging environments where other materials may not perform as effectively.
