Products classified under HTS 7224.10.00
Maraging C250 Nickel Alloy Steel Ingots
Vacuum induction melted ingots of Maraging C250 ultrahigh-strength steel with 18% nickel for rocket motor casings. HTS 7224.10.00 as primary other alloy steel, distinguished from stainless by processing.
AISI 4140 Alloy Steel Ingots
Cylindrical ingots of AISI 4140 chromium-molybdenum alloy steel, produced via electric arc furnace melting for further processing into bars or forgings. Classified under HTS 7224.10.00 as ingots of other alloy steel in primary form, not meeting specific tool steel or high-strength steel definitions in chapter notes.
AISI 4340 Nickel-Chromium-Molybdenum Steel Ingots
Large remelted ingots of AISI 4340 low-alloy steel used in aerospace and automotive forgings, containing nickel, chromium, and molybdenum. Falls under HTS 7224.10.00 as primary forms of alloy steel not qualifying as tool, ball-bearing, or heat-resisting steel per chapter notes.
AISI 8620 Carburizing Steel Ingots
