Processing & Heat Treatment

Cold Drawing: Improves surface finish and mechanical properties.
Annealing: Softens the wire for further processing (heating to 650–700°C, slow cooling).
Quenching & Tempering: Increases hardness (quench in water/oil, temper at 400–600°C).
Spheroidize Annealing: Enhances machinability.

Packaging

Coiled on spools or in bundles.
Protected with anti-rust oil or PVC coating.
Packed in wooden crates or steel straps for heavy-duty transport.

Applications

Fasteners: Bolts, screws, and studs.
Springs & Wire Forms: Moderate-stress applications.
Shafts & Axles: Machinery components.
Agricultural Tools: Blades and cutting parts.
Automotive Parts: Gears, connecting rods.
