Abstract:  
AN IMPORTANT ASPECT of archiving shot-peened Almen strips is the packaging and location for long-term storage. After years of storage, the last thing one wants to find in the archive is a paper envelope with rusted Almen strips, making verification of the arc height test results impossible. So, how should shot-peened strips be packed to prevent rust? Rust is formed when a moist steel surface meets the oxygen in air. But let’s not get into the chemical details; rather let’s focus on how to provide an environment where rust is inhibited and prevented.
