AMPP Basic Corrosion Certification Practice Exam 2025 – Comprehensive Prep

Question: 1 / 645

What is a defining feature of super austenitic stainless steels?

Low alloy content

High alloyed FCC structure

Super austenitic stainless steels are characterized by their high alloy content, specifically a significant proportion of nickel and molybdenum. This high alloying not only contributes to their excellent corrosion resistance but also results in a face-centered cubic (FCC) crystal structure. The FCC structure is crucial because it provides these alloys with remarkable toughness and strength, particularly in corrosive environments.

The enhanced alloying elements present in super austenitic stainless steels help improve their performance in chloride environments, making them suitable for applications such as oil and gas production, chemical processing, and desalination plants. The unique properties derived from their high alloyed FCC structure enable these materials to resist pitting and crevice corrosion, which is essential for maintaining integrity and longevity in harsh conditions.
