What is Duplex Steel Tube ?

Duplex Steel Tube is a registered trademark (of Special Metals Corporation) referring to a family of austenitic nickel-chromium super alloys, Duplex Steel seamless Tube is typically used in applications where high temperatures are present due to a thick, stable passivating oxide layer which is formed. Inconel® is a nickel-based alloy with superior corrosion resistance and temperature performance to stainless steel. Duplex Steel Tube is a material that is specifically optimized for some of the toughest use conditions. Duplex Steel welded Tube alloys or superalloys are nickel-based alloys that exhibit traits such as high resistance to corrosion, oxidation, carburization, pitting, crevice, corrosion cracking, and high temperature strength. Duplex Steel clad Tube are generally known for their resistance to oxidation and ability to maintain their structural integrity in high temperature atmospheres
