Is It Possible To Compare The Resistance To Chloride Attack Of Several Materials Of Construction? |
|
Answer» The Pitting Resistance Equivalent Index (PRE) can be used for such a comparison if the CHEMICAL make-up of each MATERIAL is known. The formula for the PRE is PRE = % Cr + (3.3 x % MO) + (30 x % N). The Pitting Resistance Equivalent Index (PRE) can be used for such a comparison if the chemical make-up of each material is known.
