Is stainless steel guaranteed to not rust?

Under what conditions is decorative stainless steel prone to rusting?

After bending, twisting, and folding, stainless steel is prone to pitting corrosion and rusting due to the occurrence of dislocation outcrops (i.e., the internal intergranular structure is damaged).

Why is stainless steel prone to rusting after cold deformation?

Stainless steel used for decoration rusts not only due to its own defects, but also greatly influenced by the environment, such as humidity, temperature, flow velocity, flow direction, composition and quantity of impurities in the air.

In atmospheric and weakly corrosive media, if the corrosion rate is less than 0.01mm/year, it is considered "completely corrosion-resistant".

However, rust may occur in CL media (such as salt), sulfuric acid, oxalic acid (commonly used for exterior wall cleaning), hydrochloric acid, and ceramic cleaning agents (used for interior decoration cleaning). 

How to avoid stainless steel rusty ?

Neutral substances (such as water) should be used for frequent cleaning during maintenance to reduce the adhesion of corrosive media and rust. In addition, sharp objects (such as blades and wire brushes) should be avoided from scratching to avoid affecting the appearance and damaging the intergranular structure and rusting.
