Soft annealed wire offers excellent flexibility, uniform and consistant softness, and stiffness through the process of oxygen free annealing.
Annealed wire processes normally goes from Q195 wire rod through wire drawing into black wire, then the prime raw material goes through oxygen-free heat annealing. Also known as thermal annealing.
Annealing Technology: The wire materials go through over 1000 degrees high temperature calcination (the process will maintain enough time), then to appropriate cooling rate. The purpose is to reduce the hardness, improved machinability; elimination of residual stress, stable size, reduce the deformation and crack tendency; grain refinement, restructuring the organization, eliminate defects in the organization.
Annealing is divided into oxygen free annealing, open-hearth annealing used in galvanizing and heat annealling which is commonly used in factories.
Annealed Wire is oil tampered after annealing process to add the anti-rusting property.
Annealed wire is mainly used as binding wire, fencing wire, mesh wire in wire mesh manufacture, construction reinforcing, agricultural and daily bundling uses.
