Black Annealing Square Tube Making Process

The production process of black annealed square tube is as follows. Firstly, place the black square tube into the heating furnace. Secondly, slowly heat the square tube to a certain temperature and maintain it for a period of time. The third step is to cool the heated black square tube at an appropriate speed, usually slowly, and finally obtain the desired black anneal square pipe.

Black Annealing Square Steel Tube Benifit

Comparing annealed and unannealed square tubes, annealed square tubes have the following advantages:

>>Softening: annealed square tubes are less hard and easier to machine and deform.

>>Improved plasticity and toughness: annealing significantly improves the plasticity and toughness of square tubes, reducing the risk of fracture.

>>Homogenize the organization and composition: annealing can make the organization and composition of the square tube more uniform and improve its mechanical properties.

>>Reducing residual stress: annealing can eliminate or reduce the residual stress generated during the manufacturing process of square tubes, reducing the risk of deformation and cracking.
