Alloy Steel Wire (Excluding Stainless)

Alloyed with elements such as manganese, chromium, boron, or molybdenum — but not meeting the chromium threshold for stainless classification — this wire category serves demanding mechanical applications including springs, tire cord, bearing components, and high-strength fasteners. The specific alloying elements and their concentrations are the defining commercial and classification criteria separating this heading from both non-alloy and stainless wire. Section 232 tariffs cover alloy steel wire, and the high-performance nature of many grades means that technical mill certifications and traceability documentation are standard procurement requirements. Spring wire and tire bead wire are among the most actively traded subcategories within this heading.
