A common correlation is that the higher the tensile strength, the higher the fatigue strength. Thus, the use of cold-worked stainless steel appears reasonable. No data were found...

... as a possible replacement material for the cable stops. Nitronic 60 is a manganese austenitic stainless steel. The most significant effect of the manganese is an increase in strength [ 3 ] and galling resistance. Another advantage of Nitronic 60 is that it remains fully austenitic at high levels of cold work...
