MAB and NAB alloys

Aluminum bronzes have widespread applications where a specific level of durability and resistance is required. Two of the most common are the Manganese Nickel Aluminum Bronze (MAB) and Nickel Aluminum Bronze (NAB).
Depending on the job, there are a range of comparisons which can be made to ensure the correct material is selected including differences in mechanical properties, weight saving potential, and corrosion resistance.

Corrosion Fatigue

Corrosion fatigue occurs through accumulated load cycling resulting in localized irreversible cyclic plastic deformation with as a result of chemical or electrochemical reactions.
Fatigue is already often described as the most common cause of engineering failure and when a corrosive environment is introduced, there are no guarantees for a safe stress range at all.

Production of HIC Resistant Steels

Hydrogen induced cracking (HIC) represents a common challenge, especially in the petroleum and refinery industry where the purity and overall quality of the steel is of paramount importance.
The production process for HIC resistant steels includes critical desulphurization techniques including the injection of magnesium and stirring by bottom argon injection.

Corrosion of Zirconium Alloys: Part Two

Zirconium is a common choice for nuclear applications due to its low thermal neutron capture cross section which is about 30 times less than that of stainless steel.
A specific key useful benefit of zirconium alloys are their specific resistance to acids including hydrochloric, sulfuric and phosphoric acids which means applications which require direct contact with these substances is particularly suited.
