I have detected different intensity measurements based on different strip hardness.
Altought the strip hardness meets always the spec (44-50 HRC), we have found what I understand significant differences (> 0,01 mm) in the measurement intensitty when we used strip in the lowset hardness range or in the upper hardness range.
The shot peening spec. is 0,15-0,2 mm Almen C; 100% coverage; shot size: 330. The part is a carburized gear.
Could anyone share its experince in this issue?
