We are the most favored manufacturer to manufacture Duplex Steel 2205 flanges for critical applications, producing and storing even odd sizes and elusive ribs in duplex steel and super duplex steel. We manufacture S31803 blind flanges of duplex steel, Duplex steel threaded flanges, S32205 duplex steel hole flanges, duplex steel 2205 WNRF flanges, duplex steel sliding flanges, duplex steel junction flanges, duplex steel reducing flanges, steel duplex weld flanges and all shapes and sizes in duplex steel and duplex steel material. Our duplex steel is in accordance with ASME B16.9, ASME B16.28. standard. Duplex Steel 2205 flanges are designed in such a way that they have features such as impeccable finish, robust design and oxidation resistant. At Gnee Steel Group we make sure that our product goes through several levels of quality phase and ensures timely delivery of the product.
Duplex stainless steel 2205 is a nitrogen-enhanced duplex stainless steel that was developed to combat common corrosion problems encountered with 300 series stainless steels. "Duplex" describes a family of stainless steels that are not completely austenitic, such as 304 stainless steel, nor purely ferritic, such as 430 stainless steel. The structure of duplex stainless steel 2205 consists of austenite pools surrounded by a continuous ferrite phase. In the known condition, 2205 contains approximately 40-50% ferrite. Often known as the degree of workhors, 2205 is the most widely used degree in the stainless steel duplex family.
