The processing technology of Q235NH corten steel has brought great convenience to our daily life, but many problems will also occur during the use of the product. The defects of Q235NH corten steel during production and the protection of micro-cracks are induced by induction heating and bending. Q235NH corten steel exceeds a certain level of deformation temperature.
If micro-cracks appear on the outside of the Q235NH corten steel, this situation will have a certain relationship with the material of the bent Q235NH corten steel. Under the similar forming conditions with low deformation speed and high tensile resistance, the equipment is in such a condition Under all circumstances, all bending operations may cause damage to this material.
If micro-cracks of Q235NH corten steel appear, the forming conditions can be effectively used in the process of use, and the length of the cracks can usually effectively reach the main cracks and the direction of stress is perpendicular to the austenite grain boundary.
After being bent, the corten steel of Q235NH causes its structure to crystallize after its heat treatment, so that the microcracks become crystal pulls. At room temperature and higher temperatures, the yield strength and tensile strength will not be affected, but the microcracks will be affected. There is a noticeable change in the impact value of the induced groove.
In the process of processing, its different bending radius and bending angle of Q235NH corten steel are used to change the direction of pipeline operation. Such products will become an essential part of connecting pipelines in pipeline engineering.
The bending process technology of Q235NH corten steel is very important in the process of manufacturing. Pipe manufacturing technology and the construction principle of large-scale Q235NH corten steel equipment can be created in the pipeline engineering of China's power, petroleum, chemical, transportation and other industries.
