Abstract: The evaluation of strain aging was a difficult problem for in-service and un-sampling equipment. The 16Mn pipe was used as research material. The values of yield strength, tensile strength, impact absorbing energy and fracture toughness of the material which before and after the strain aging were compared by the automatic ball indentation tests and conventional mechanical experiments. And the application of the automated ball indentation tests in the strain aged steel was further discussed. The results showed that the automatic ball indentation tests could be used to accurately measure the mechanical properties of the material after the strain aging. So the mechanical performance of the in-service equipment could be acquired regularly by the automatic ball indentation technology, and according to the actual test mechanical properties to adjust operating pressure or replacement equipment, it could facilitate the safe operation of equipment, moreover it could extend the service life of equipment.

Key words: 16Mn steel, strain aging, mechanical property, automated ball indentation, in service
