Products classified under HTS 7224.90.00.75
Modulus Alloy Steel Semi-Finished Bloom
Bloom of modulus alloy steel (high silicon/chromium) for damping applications. Classified as other under HTS 7224.90.0075.
Aermet 100 Ultra-High Strength Alloy Ingot
Premium Aermet 100 cobalt-nickel alloy steel ingot for aerospace. HTS 7224.90.0075 as other primary alloy steel form.
AISI 4140 Alloy Steel Round Billet
A hot-rolled round billet made from AISI 4140 chromium-molybdenum alloy steel, used for manufacturing shafts and gears. Classified under HTS 7224.90.0075 as a semi-finished product of other alloy steel in primary forms, not meeting specific alloy definitions like tool steel or high-strength steel. It is further worked through hot rolling but remains in billet form prior to final forging.
AISI 4340 Nickel-Chromium-Molybdenum Steel Slab
Flat-rolled slab of AISI 4340 alloy steel containing nickel, chromium, and molybdenum, primarily for aerospace components. Falls under HTS 7224.90.0075 as other semi-finished alloy steel products not qualifying as universal mill plate or other specified types. It is in primary form suitable for further hot working.
17-4 PH Precipitation Hardening Stainless Steel Bloom
Rectangular bloom of 17-4 PH stainless alloy steel used in valves and fittings, with chromium ~17% and nickel ~4%. Classified in HTS 7224.90.0075 as other alloy steel semi-finished products, as it does not match specific tool or razor blade steel definitions despite high chromium.
AISI 8620 Carburizing Alloy Steel Billet
Square billet of AISI 8620 low-alloy steel for case-hardened gears and pinions. HTS 7224.90.0075 covers this as other semi-finished alloy steel, not fitting ball-bearing or chipper knife steel specs. Provided in primary form for forging or rolling.
AISI 4130 Chromoly Steel Round Bloom
Cylindrical bloom of AISI 4130 chromium-molybdenum steel for aircraft tubing. Under HTS 7224.90.0075 as other alloy semi-finished, excluding high-strength or tool steel categories per U.S. notes.
EN24 Alloy Steel Forging Ingot
Large ingot of EN24 (similar to 4340) alloy steel for heavy forgings like crankshafts. Classified HTS 7224.90.0075 for other alloy steel primary forms, not further worked beyond casting.
AISI 9310 Gear Steel Semi-Finished Billet
Billet of AISI 9310 nitriding alloy steel for high-performance gears. HTS 7224.90.0075 as other alloy semi-finished, not ball-bearing steel despite similar use.
HY-80 High-Yield Alloy Steel Slab
Slab of HY-80 nickel-alloy steel for naval shipbuilding plates. Under HTS 7224.90.0075 as other semi-finished alloy steel, pending specific high-strength classification.
AISI 52100 Chromium Alloy Steel Bloom
Bloom of AISI 52100 high-carbon chromium alloy for bearings, not exactly matching tool steel note. HTS 7224.90.0075 for other alloy semi-finished products.
Maraging Steel 18Ni300 Semi-Finished Ingot
Ingot of 18Ni300 maraging steel for rocket motor cases, ultra-high strength alloy. Classified HTS 7224.90.0075 as other alloy primary form.
AISI 4330V Modified Alloy Steel Billet
Vacuum-melted AISI 4330V billet for landing gear forgings. HTS 7224.90.0075 covers this modified alloy semi-finished product.
Nitralloy 135 Alloy Steel Slab
Slab of Nitralloy 135 for nitrided components, aluminum-bearing alloy steel. Other alloy semi-finished under HTS 7224.90.0075.
AISI 8740 Alloy Steel Forging Billet
Octagonal billet of AISI 8740 chromium-nickel steel for fasteners. HTS 7224.90.0075 for general alloy semi-finished.
