Annealed wire is a kind of used in construction, petroleum, chemical industry, farming, landscape protection wire, it can play the role of a good reinforcement and protection.
Annealed wire has applied in many places, it has a very popular type, galvanized wire, black annealed wire.
So, black annealed wire, and what is the difference between ordinary annealed wire?
Here, you can to get to know it.
1, black annealed wire than annealed wire is more soft, better flexibility, softness and uniform, the chromaticity, black annealed wire has stronger antioxidant properties, it is made of low carbon steel cold drawn, heating and constant temperature, heat preservation and become a kind of soft wire products.
2, black annealed wire material is generally composed of Q195 wire rod drawing model into the black iron wire.
After selected raw materials keep enough time through 1000 degrees high temperature firing, and cooling with appropriate speed.
The purpose is to reduce the hardness and improve cutting machining;
Eliminate the residual stress, stable size, reduce the deformation and crack tendency, refine the grain size, adjust the organization, remove the tissue defects, let us in use can be very good quality.
Through the above introduction, believe that you already know that black annealed wire, and what is the difference between ordinary annealed wire.
