ASTM A182 Duplex Steel threaded flanges are commonly used in various industrial applications that require high strength, corrosion resistance, and durability. These Duplex Steel threaded pipe flanges are made from a combination of austenitic and ferritic stainless steels, which makes them highly resistant to corrosion and wear. One popular type of ASTM A182 Duplex Steel threaded flange is the DSS RF threaded flange. This flange has a raised face that provides an additional sealing surface, which makes it ideal for applications that require a tight seal.

What is the chemical composition of Duplex steel threaded pipe flanges?
Duplex steel threaded pipe flanges typically contain chromium, molybdenum, and nickel, which provide high strength and excellent corrosion resistance. They also contain a small amount of nitrogen, which enhances their mechanical properties.
How does carbon content affect the properties of DSS threaded flanges?
Carbon content can affect the mechanical properties of DSS threaded flanges, such as hardness and strength. Higher carbon content can increase the hardness and strength of the material but can also reduce its flexibility and impact resistance.
