Corrosion is also so beautiful
Thread Content
Could you please give me some guidance on how this happened?: After the stainless steel storage tank equipment was filled with water for 3 days, a circle of this kind of mark appeared on the inner wall of the equipment, which seemed to be under the surface. I wiped it with a cloth, but there was no response. ； Can be removed with a wire brush
It should be that the outside of the cylinder plate has been moved or heated, and the material of the plate has changed, so a circle of marks will appear.
Yes, the art of "edging" in stone and stone seal carving is to create a sense of vicissitudes corroded by time;P
Has the material been denatured by heat? There is probably a structure like a reinforcing ring on the outer surface, and it is fully welded.
Not corrosion! Caused by excessive heat
This is obviously caused by heating :)
A caring person! The photos were taken very well.
Is the surface pickling of the stainless steel not done after heating? Suspected to be caused by welding. It happens selectively
