Corrosion Resistance |
---|
Good corrosion resistance in industrial atmosphere, freshwater,
steam, alcool, ammonium, several oilfield products and organic
compounds, dairy products, mild acid environments. Fairish in
foodstuff and alkaline solutions. Fair in salt atmosphere. It does
not resist in contact with sea water and strong acids (even if
diluted). |
