An acid is more corrosive when the pKa is lower (or Ka is higher) or is a strong acid. Corrosion happens when a lewis acid gains electron pairs from metal atoms. This makes the metal atoms positively charged, in order to counteract that the metal cation will be oxidized with surrounding oxygen and undergo a chemical reaction as it corrodes.
