The service life of stainless steel furniture will not rust in the normal environment within 4 or 5 years, but the surface will be blurred and the texture will become worse after a long time of use. If it is outdoors in some coastal cities, it will rust faster.

Because the air in these places is relatively humid, if placed on the beach and soaked by seawater, this seawater with alkaline corrosion components will cause rust of ordinary stainless steel furniture in a very short time.
