Annealed black iron wire is a soft iron wire product that has been treated by annealing process. It effectively improves the elongation of the material by heating at high temperature and then slowly cooling it.
This treatment makes the iron wire easier to bend and form, and is suitable for scenes that require repeated shaping or stress, such as industrial bundling, hand weaving and other fields.
Process principle
Annealed black iron wire increases the elongation by heating the cold-drawn black iron wire to the critical temperature and then slowly cooling it to eliminate the residual stress inside the material.
Performance advantages
1. The elongation is significantly improved
2. The surface oxide layer remains intact, and the anti-rust ability is not significantly affected
3. The tensile strength is still maintained after processing
Application areas
Mainly used in scenes with high requirements for material flexibility, including:
Metal craft weaving
Steel bar bundling in the construction field
Agricultural greenhouse frame fixation
Connector forming in furniture manufacturing
This product increases the elongation of the iron wire through the annealing process.
