Yes, while the grades of stainless steel used in today's DE blades are resistant to corrosion, they are not impervious to it.I shave daily, and 9/10 shaves are with straight razors, the rest are DE shaves. I have noticed that the number of days between use also factor in. A blade that has been used one time, and if it sits in the razor for a couple of weeks it seems to be degraded, probably from oxidation.
I can usually get 4 to 6 good shaves out of most blades if I use one blade each consecutive day.
Some razors are also gentler on the blade. Rigid blade support seems to do worse.
