Overview
Black Annealed Steel Wire combines low-carbon carbon steel with a heat-treated annealed condition and dark oxide surface for reliable ductility, soft handling and consistent dimensional control. The annealed temper and flexible coil format make the wire suited to binding and baling, agricultural fencing, general fabrication, tying applications and light industrial service. Supplied to ASTM A510 / EN 10218-2 with mill test certification per EN 10204 3.1, it supports global procurement for utility, agricultural and general industrial supply chains.

FAQ
Most enquiries reduce to a small set of recurring technical questions.
01 What is black annealed steel wire?
Black annealed steel wire is produced from low-carbon steel wire rod that has been annealed (heat-treated) to improve ductility. The dark surface oxide is the "black" finish.
02 What is black annealed wire used for?
Black annealed wire is widely used for binding, baling, tying, general-purpose packaging, construction tie wire and craft applications.
03 What diameters are available?
Common diameters range from 0.5 mm to 6.0 mm. Special diameters can be produced to project specification.
04 What packaging is standard?
Coil form is standard, typically 25 kg, 50 kg or 100 kg coils. Custom coil weights and reel / spool packaging are available.
05 Is mill test certificate provided?
EN 10204 3.1 mill test certificate with chemical composition is standard for batch-certified wire.
