Conforming to JIS G3532 SWM-B(Low Carbon Steel Wire) and SWM-A(Annealed Wire). Mechanical properties of the wire can be in a strict range based on our severe control of drawing dies and annealing temperature.

This wire has a clean surface (less oxidized layer) and a good rust-preventive quality which are provided by controlled annealing in reducible atmospheric gas and by special surface treatment.
