Black Annealed Twist Iron Wire

Material: black annealed iron wire

Features: Black annealed wire is rust proof within 6 months without any oil coating. The tensile strength is 300-400 Newton per square millimeter.

Process and Technology:
Black annealed wire is made of Q195 wire rod drawn as raw materials. After selecting the raw materials by about 1000 ° high temperature and then coolned to a suitable speed. The purpose is to reduce the hardness, improving machine ability; eliminate residual stress, stable size, reduced distortion and cracking tendency; refied grains, adjust the organization and eliminate tissue defects.

Application: Black annealed wire is mainly used as industrial wire, construction wire, industrial bale tie wire and constructional tie wire, etc.

Packing:
25/50kg/coil; 5-10kg/coil; 0.4-1.0kg/coils, 10coils/bundle; plastic film inside and hessian/woven bag outside or according to the customers' requirement.
