Effect of Low Temperature Steel Ball Peening on the Hardness of SS 316L
The aim of this research is to investigate the hardness of implant material Stainless Steel (SS) 316L due to ball peening at low temperature. In this paper, SS316L ball peening was conducted in various cryogenic temperature. The steel ball peening mechanism was bombarded on metal surface using peening ball. The shot peening treatment was performed for 10 minutes using steel balls with the size of 5 mm and 6 Bar compressed air flow. The treatment temperatures were carried out at-35°C, -45°C, and-55°C respectively. The results show that the hardness of SS316L after steel ball peening processes increasing as decreasing temperature treatment.
