PENGARUH BALL PEENING TERHADAP KEKERASAN BAJA TAHAN KARAT AISI 316L
Abstract: In this work, ball
peening was performed in order to evaluate its effect on the AISI 316L hardness.
The process was conducted by employing AISI E52100 Chrome Steel ball which hashardness
752 HVN as bomber. In this research ball peening process was performed at threedifferent
nozzle pressure (6, 7, and 8 bar) for 5 minutes. Vickers Micro Hardness Tester
and Digital Optical Microscope was used to characterize the samples hardness
and grains structure respectively. The results showed that the hardness of AISI
316L was improved. It may due to plastic deformation which toke places on its
grains
