Sheet metal processing, stainless steel processing, stainless steel products, 304 stainless steel plate surface treatment should pay attention to which aspects? The surface quality of 304 stainless steel plate is mainly determined by the pickling process after heat treatment. If the surface oxide skin formed by the previous heat treatment process is thick, or the organization is not uniform, the pickling can not improve the surface finish and uniformity. Therefore, we should pay full attention to the heating of heat treatment or surface cleaning before heat treatment.
