Product Spotlight: Springs in Hydrogen Sulfide (H2S) Applications

Hydrogen Sulfide is an aggressive corrosive agent, that is known to attack and cause rapid failure of springs and other metal components. Platings and coatings are of limited value, because small flaws can still lead to corrosive attack, and initiate fractures in the metal. In springs, materials that are widely used include:

Each of these alloys are recognized by NACE to be acceptable in H2S environments. They have varying degrees of strength, and resistance to corrosion. MP35N and Elgiloy are also resistant to sea water attack, and have better strength than X750. Because of their strength, then can also be used to make more space-efficient designs, which can improve system performance, and reduce cost.
