Coefficient of friction and wear rate of different austenitic steel materials are investigated and compared. Experiments are conducted on a pin/ball-on-disk apparatus on different types of ball materials such as austenitic stainless steel SS304 and austenitic stainless steel SS316 sliding against EN-31 disk. The experiments are performed on a group of specimens for duration of 5 min for various loads of 10,15 and 20 N in magnitude with sliding velocity...
