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). |
