Products classified under HTS 7224.90.00.05
Incoloy 800 Semi-Finished Billets
Incoloy 800 is a high-nickel alloy steel (over 30% nickel) used in semi-finished billet form for high-temperature applications like heat exchangers. It falls under HTS 7224.90.00.05 as a primary form of high-nickel alloy steel, not further worked beyond basic shaping. These billets are typically hot-rolled or forged for subsequent machining into components.
Hastelloy C-276 Ingots
Hastelloy C-276 ingots are high-nickel alloy steel (Ni ~57%) primary forms resistant to corrosive environments like chemical processing. Classified under HTS 7224.90.00.05 for high-nickel alloy steel in ingot or primary forms. These are melted and cast shapes ready for remelting or forging.
Monel 400 Slab
Monel 400 slabs are high-nickel/copper alloy steel semi-finished products (Ni 63-70%) for valves and pumps in seawater applications. Falls under HTS 7224.90.00.05 as other high-nickel alloy steel primary forms. Slabs are thick flat-rolled precursors under 1.5m² cross-section.
Alloy 20 Bloom
Carnegie Alloy 20 bloom is high-nickel (32-38%) austenitic steel semi-finished for sulfuric acid handling equipment. HTS 7224.90.00.05 applies to such high-nickel alloy semi-finished products. Used in chemical industry for corrosion resistance.
Incoloy 825 Ingot
Incoloy 825 ingots feature high nickel (38-46%) with molybdenum for oil/gas downhole tools. Classified HTS 7224.90.00.05 for high-nickel alloy primary forms. Cast shapes for remelting into wire or plate.
Nimonic 80A Semi-Finished Bar Stock
Nimonic 80A is high-nickel superalloy (Ni 72%) semi-finished bar for gas turbine blades. HTS 7224.90.00.05 covers high-nickel alloy steel in primary/semi-finished forms. Hot-worked but not machined or surface treated.
ELGILOY High-Nickel Wire Bloom
ELGILOY cobalt-nickel alloy blooms (Ni 40%) for spring wire in medical devices. Under HTS 7224.90.00.05 as high-nickel alloy semi-finished for further drawing. Rectangular section precursor to fine wire.
Inconel 625 Bloom
Inconel 625 bloom is a semi-finished high-nickel alloy steel product (Ni 58%) with rectangular cross-section over 150mm wide, used in aerospace and marine turbines. HTS 7224.90.00.05 covers other alloy steel semi-finished products of high-nickel alloys. Not further worked per chapter definition.
