Stainless steel wire rod

Hot-rolled round stainless steel in coils, typically 5.5–20 mm in diameter, supplied annealed and pickled to wire drawers. It is the raw material for stainless wire, springs, cold-headed screws and bolts, welding wire, mesh and wire rope.

Overview

Wire rod is the smallest hot-rolled long product: a round section rolled at high speed on a rod mill and laid in rings, which are collected into coils. For stainless steel the coils are then solution-annealed (for austenitic grades) and pickled to remove scale, because the drawer needs a clean, soft, uniform surface.

Each end use calls for a different rod. Cold heading for screws and bolts needs a grade with low work hardening — 304 with added copper, sold as 304HC or 304Cu, or 302HQ — and very good surface quality. Spring wire needs high strength after drawing. Welding wire rod is melted to tight composition ranges for the filler metals 308L, 309L and 316L. Ferritic 430 and martensitic 410 and 420 rod go into fasteners, knives and appliance parts.

Wire rod is supplied by integrated stainless producers in China, India, Korea, Japan, Taiwan and Europe. Regional fastener, mesh and welding wire producers in the GCC import most of their stainless rod, mainly from Asia.

Forms & sizes

Rod is ordered by diameter, grade, condition and end use; the end use matters because the mill controls the chemistry and surface differently for cold heading, spring or welding grades.

Diameters
5.5, 6.0, 6.5, 7.0, 8.0, 9.0, 10, 12, 14, 16 and 20 mm are common
Condition
Annealed and pickled (most austenitic grades); annealed or as-rolled for ferritic and martensitic grades
Coils
Typically 0.5–2 t, strapped, with tags giving heat number, grade and size
Bar-in-coil
Larger diameters, about 16–40 mm, coiled for straightening and cutting

Buying tips

What to specify

  • Grade, standard and end use (drawing, cold heading, spring or welding) — the mill sets surface and chemistry limits accordingly.
  • Diameter and its tolerance and out-of-roundness.
  • Condition: annealed and pickled, or black; and maximum hardness or tensile strength for cold heading.
  • Coil weight, inner diameter and packing, to suit the buyer's pay-off equipment.
  • Surface quality limits (depth of seams and laps) and any eddy-current testing.
  • An EN 10204 3.1 certificate per heat with full chemistry, including copper and nitrogen for heading grades.

Quality checks

  • Check coil tags against the certificate and identify the grade with a portable XRF on each heat.
  • Measure diameter and ovality at both ends of sample coils.
  • Inspect the surface for seams, laps, scratches and residual scale.
  • Do a trial draw or upset test from each heat before committing a production run.
  • Check hardness or tensile strength against the order for cold heading rod.
