Product Details

Black Iron Wire (Material is Q195/235)Annealed or Unannealed

1.Product(manufacturing technique)

Steel rod coil-wire drawing-wire annealing-rust removing-acid wasting-boiling-drying-zinc feeding-wire coiling

Wire Rod(low carbon steel, ISQ195, ASTM,SAE 1006/1008)
Wire Drawing(draw 6.5mm wire to 4.mm or other diameter, two types of drawing methods)
Annealing(wire go through the high temperature, improve T/S, preparation for the zinc coating)
Wire Coiling(Weight of coil/roll: 200kg, 100kg, 50kg, 25kg, 10kg, 2-8kg)

Annealing is the key determinant of the wire T/S(Tensile Strength)
