Almen Strips
An Almen Strip is a thin strip of SAE 1070 steel used to quantify the intensity of a shot peening process.
Almen strips are classified into 3 types: 'A', 'N', and 'C'.
- Almen Strip "A" type is predominantly used for shot peening with cast shot or cut wire shot.
- Almen Strip "N" type are used usually for glass bead peen and ceramic bead peen.
- Almen Strip "C" type are used more rarely and are thicker than the other types.
The Almen strips are made from plain carbon steel SAE 1070 and have hardness about 45 HRC.
This test is widely used and the requirements for check are specified in standards. The most rigid requirements are applicable for Almen strips and checking devices (Almen gauges) used in the aerospace industry. The generic requirements can be found in SAE specifications.
