Dataset on compressive shot peening residual stresses condition in SAE 5160 and DIN 51CrV4 spring steels

This dataset presents measurements of the compressive residual stresses introduced by shot peening in spring steels, specifically SAE 5160 and DIN 51CrV4. These near-surface stresses are vital for extending the fatigue life of critical components such as leaf springs. The dataset focuses on the potential reduction or redistribution of these beneficial stresses during subsequent thermal processes—specifically, paint curing simulations involving oven heating at 80, 160, and 200 °C with varying exposure times. It provides complex, raw quantitative data suitable for validation and reuse in materials engineering and fatigue studies.
