Corrosion Resistance
Alloy 410 is resistant to atmospheric conditions, water and some
chemicals. It can be used in environments containing weak or diluted acetic
acid, naptha, nitric acid and sulfuric acid. The alloy is also resistant to acids
contained in foods.
410 can also be used in slightly chlorinated and desaereted water. It
performs well in oil and gas applications where desaereted and low
hydrogen sulfide exist. However, the alloy is prone to chloride attack,
particularly in oxidizing conditions.
410 operates well in environments requiring moderate corrosion resistance
and high mechanical properties
