Can the stainless steel cup be filled with saline?

All stainless steel water cups on the market should be tested for salt spray.The purpose is to test whether the material will rust in an environment with high salt spray concentration.Within the specified test time and concentration, stainless steel will be regarded as a qualified material without rusting.

Therefore, the stainless steel water cup can be filled with physiological saline, but once the filling time exceeds the allowable time of the material, the salt will still corrode the material and eventually cause rust.

Because the pipe processing methods of stainless steel water cups are divided into welding and stretching.Due to different processes, the effect on the salt spray reaction is also different.The welded pipe has already damaged the stainless steel at the welding seam during welding, so once such a water cup is filled with physiological saline, it is more prone to corrosion and rust.The most obvious is the blackening of the wire.Since the pipe drawing process does not require welding, it can take a longer time to install the saline solution.
