Product Name: High-Speed Rolled Low Carbon/Alloy Wire Rod

Overview

Wire Rod is a long, semi-finished steel product with a round cross-section, produced by hot rolling billets into coils or straight lengths. It serves as a primary raw material for drawing into wires or manufacturing fasteners, springs, and reinforcement components. Produced at 100m/s speed with ±0.1mm diameter tolerance. Grades: SWRCH (cold heading), 72A-82B (spring), ER70S-6 (welding wire) for fastener, spring, and wire manufacturing.
