In question 25 48:39 why stainless steel resist corrosion unlike mild steel

[@farhanurtasnuba7209]

due to difference in their composition, stainless steel contains chromium which allows it to resist corrosion

[@hiiiii137]

You can also think in this way that all our cutlery is made from stainless steel. So if it would've resist corrosion all our cutlery could be covered with rust. But this isn't the case, so obv it resists corrosion
