Products classified under HTS 7304.51.50.05
Incoloy 825 Seamless Cold-Drawn Tube
Incoloy 825 is a high-nickel alloy steel (Ni-Fe-Cr alloy with >38% nickel) used for seamless cold-drawn tubes in corrosive environments like chemical processing. These tubes have a circular cross-section, are cold-rolled for precision, and fall under HTS 7304.51.50.05 due to their high-nickel composition and seamless construction. They are ideal for heat exchangers and piping in harsh industrial settings.
