Product use: black iron wire

Black iron wire material:

Black annealed wire

Black wire features:

Rust proof for 6 months,

The tensile strength is 300-400 Newtons per square millimeter.

Process and technology:

Black annealed wire is made of drawn Q195 wire.After the raw material is selected, it is cooled to a suitable speed at a high temperature of about 1000°.The purpose is to reduce the hardness, improve the mechanical ability;Eliminate residual stress, dimensional stability, reduce deformation and cracking tendency;Fine particles, adjust the organization, eliminate organizational defects.

Uses: Black annealing line is mainly used for industrial line, construction line, industrial strapping line, construction strapping line, etc.

Packing:

25/50kg/coil;5-10kg/coil;0.4 -- 1.0 kg/roll,10 rolls/pack;Inside plastic film, outside gunny bag or woven bag, also can be customized according to customer requirements.
