Refinish paint is a hard film that can be directly bonded to the substrate. There are many corners and edges on WN Flange. Due to the thinning of the edges, although thicker coatings can handle edge protection, it is difficult for traditional coating systems to effectively cover the edges.
Heat treatment usually does not change the shape and overall chemical composition of the workpiece, but by changing the internal microstructure of the workpiece or changing the chemical composition of the surface of the workpiece, thereby imparting or improving the performance of the workpiece, which is characterized by improving the internal quality of the workpiece. It is invisible to the naked eye.
The passivation process of flanges can be divided into two types: wet method and dry method. Specifically, it can be divided into many types. The passivation of the flange depends on the passivation process and the material itself. The specific influencing factors include the metallographic structure of stainless steel and the processing state of stainless steel.
