Will the authentic 304 stainless steel pump rust?

Q: Can the authentic 304 stainless steel pump rust?

Answer: Can not arbitrarily say that stainless steel 304 material pump will not rust, depending on the situation. Because stainless steel material contains chromium, nickel, titanium and so on. Chromium and nickel elements have anti-rust function, which forms a protective film-blunt film to prevent stainless steel from rusting.

Under normal circumstances, as long as the film is not damaged, cracked or contaminated by impurities, stainless steel will not rust. However, if the use or maintenance is not proper, the passivation film is damaged, and the stainless steel will rust.
