Products classified under HTS 7217.10.80.30
1.2mm Heat-Treated High-Carbon Spring Wire
Round wire of nonalloy steel with 0.6% or more carbon content, heat-treated for enhanced tensile strength, and sized at 1.2 mm diameter. Classified under HTS 7217.10.80.30 due to its specific diameter range (1.0-1.5 mm), high carbon composition, and heat treatment without plating or coating. Used primarily in manufacturing coil springs for automotive suspensions.
1.4mm Heat-Treated C67S Piano Wire
High-carbon steel wire (C67S grade, ~0.65% carbon) heat-treated via patenting process for musical instrument strings, diameter 1.4 mm. Fits HTS 7217.10.80.30 as round, non-plated, heat-treated wire with ≥0.6% carbon in the 1.0-1.5 mm range. Essential for piano and guitar high-tension strings requiring precise elasticity.
1.1mm Heat-Treated Music Wire ASTM A228
ASTM A228 music wire, cold-drawn and heat-stabilized with ≥0.6% carbon, 1.1 mm diameter for precision springs. Under HTS 7217.10.80.30 for its round cross-section, high carbon, heat treatment, and exact diameter specs without plating. Ideal for small instrument valves and medical devices.
1.3mm Heat-Treated Oil-Tempered MB Wire
Oil-tempered high-carbon wire (0.7% carbon) with 1.3 mm diameter for mechanical belt springs, heat-treated for fatigue resistance. Matches HTS 7217.10.80.30: nonalloy, round, ≥0.6% C, heat-treated, 1.0-1.5 mm, not plated. Used in conveyor and automotive belt systems.
1.25mm Heat-Treated Hard Drawn Lock Wire
Hard-drawn, heat-treated nonalloy steel wire (0.62% carbon) at 1.25 mm for aircraft safety wire locking. HTS 7217.10.80.30 applies to its round shape, high carbon, heat treatment, uncoated status, and precise diameter. Critical for aerospace fastener security.
1.0mm Heat-Treated Valve Spring Quality Wire
Precisely 1.0 mm heat-treated high-carbon wire (0.68% C) for engine valve springs, non-plated and polished. Classed in HTS 7217.10.80.30 for round wire traits, carbon level, heat treatment, and minimum diameter threshold. High fatigue strength for automotive engines.
