Interactive Engineering Tool
Almen Intensity Calculator
Calculate saturation points, analyze arc height data, and determine optimal peening intensity per SAE J442 standards.
Saturation Curve Analysis
Enter at least 2 exposure times in ascending order
Enter arc heights corresponding to each exposure time
Example Dataset
Exposure Times: 2, 4, 6, 8, 10 minutes
Arc Heights: 0.008, 0.012, 0.014, 0.015, 0.0155 "A
Copy these values into the calculator to see how saturation analysis works.
Saturation Criterion
Saturation: h(2T)/h(T) ≤ 1.10
When doubling the exposure time results in ≤10% increase in arc height, the process has reached saturation.
