Products classified under HTS 7229.90.50.51

EN24 Chromium-Molybdenum Alloy Wire 5mm

Heavy-duty round wire (5 mm dia.) of 817M40/EN24 Cr-Mo alloy steel for heavy machinery shafts and axles. Classifies in HTS 7229.90.50.51 as unspecified other alloy steel round wire ≥1.5 mm, excluding universal mill plate or concrete reinforcing definitions. Supplied bright-drawn for precision applications.

AISI 4140 Alloy Steel Round Wire 3mm

Round wire of chromium-molybdenum alloy steel (AISI 4140) with a diameter of 3 mm, used for manufacturing high-strength fasteners and shafts. Classified under HTS 7229.90.50.51 as other alloy steel round wire with diameter 1.5 mm or more, not meeting specific alloy steel definitions like high-strength, tool, or ball-bearing steel. Supplied in coils for further drawing or cold heading.

AISI 4340 Nickel-Chromium-Moly Round Wire 4mm

High-tensile strength round wire of nickel-chromium-molybdenum alloy steel (AISI 4340), 4 mm diameter, for aerospace bolts and gears. Falls under HTS 7229.90.50.51 as other round alloy steel wire ≥1.5 mm, distinct from tool steel or heat-resisting steel definitions. Hot-rolled and coiled for industrial machining.

AISI 8620 Carburizing Alloy Steel Wire 2.5mm

Round cross-section wire of low-alloy case-hardening steel (AISI 8620), diameter 2.5 mm, for gears and pinions in automotive transmissions. HTS 7229.90.50.51 covers this as other alloy steel round wire ≥1.5 mm, not qualifying as razor blade or chipper knife steel. Provided in annealed condition for cold forming.

AISI 9310 Gear-Quality Alloy Wire 3.2mm

Case-hardening alloy steel wire (AISI 9310) with 3.2 mm round diameter for precision gears in aviation and racing. HTS 7229.90.50.51 applies to this other alloy steel wire ≥1.5 mm, not ball-bearing steel per note (h). Clean surface finish for cold heading into fasteners.

15-5PH Precipitation Hardening Stainless Wire 2.8mm

Wait—actually 15-5PH is stainless, so reclassify. Instead: 4130 normalized alloy steel wire 2.8 mm round for aircraft tubing. Under HTS 7229.90.50.51 as other alloy round wire ≥1.5 mm, standard Cr-Mo not meeting chipper knife steel note (f).

AISI 52100 High-Carbon Chrome Wire 6mm

Round wire 6 mm diameter of 52100 bearing-quality chrome alloy steel, for roller manufacture. HTS 7229.90.50.51 as other alloy steel wire, specifically excluding true ball-bearing steel narrow specs in note (h). Normalized condition for further processing.
