Except for a few hydrogenating agents, stamping elbows are resistant to the erosion of various chemical media. They have excellent acid resistance, alkali resistance, corrosion resistance, no rust, no corrosion, no breeding bacteria, and no electrochemical corrosion.

At the same time, the welding position can also be determined. Good pre-compression time, holding time, maintenance time, rest time to ensure that the workpiece can be spot welded firmly.
