Annealed Steel Wire 10b21 3.45mm
Puyang Grand Steel Co.,Ltd supplies boron-alloyed low carbon annealed steel wire in grade 10B21, cold-drawn to a precise 3.45mm diameter with a smooth surface finish. The wire is produced to meet ASTM standards and is certified to ISO and CE, making it suitable for cold heading and fastener manufacturing where formability and dimensional consistency are critical. The material’s low carbon content, paired with boron alloying, ensures high ductility and uniform mechanical properties for high-volume production lines.
The 10B21 grade is a low-carbon boron steel, typically used in applications requiring excellent cold heading performance, such as bolts, screws, and rivets. Standard industry practice for this grade includes a tensile strength range of 450-650 MPa and an elongation of 10-20% in the annealed condition, with a typical surface roughness of Ra 0.8-1.6 µm. The wire is drawn to tight tolerances, with a standard diameter tolerance of ±0.02mm for precision applications, and is supplied in woven bag packaging to prevent damage during transit.
This wire is primarily sourced by automotive and mechanical industries for fastener production, where consistent material properties and surface finish are essential. Buyers should confirm the exact mechanical properties and certifications for their specific application, as the supplier’s production capabilities include a range of grades and specifications. The wire is available in bulk coils, and international buyers can request customized packaging or additional testing, such as hardness or microstructural analysis, to meet their quality requirements.

Sourcing Annealed Steel Wire 10b21 3.45mm from Puyang Grand Steel Co.,Ltd - China Import Guide
Before placing an order, verify the exact mechanical properties and certifications required for your application. Request a mill test certificate to confirm the chemical composition, tensile strength, and elongation of the 10B21 wire. Ensure the supplier’s production batch meets your specifications, as variations can occur between different lots.
