I am wondering about corrosion of the steel blades on my ice fishing auger. The auger is used on fresh water lakes (ie no salt involved). I have traditionally brought the auger inside to melt the ice off. Then I dry and oil the blades. I am tempted to leave the auger outside over night in the well below freezing temperature. The blades are relatively expensive and impossible to sharpen. I have no idea as to the grade of steel. It does look like a plain carbon steel.

Your thoughts would be appreciated, Grouseman

  • $\begingroup$ What is your question? Does leaving it in the well mean leaving it in sitting in ice? Or water? $\endgroup$

  • $\begingroup$ I 'm leaving it outside in the "well below freezing" temperature. I'm not leaving it in a well. $\endgroup$

  • $\begingroup$ Oh okay. You typed this "I am tempted to leave the auger outside over night in the well" If the water has frozen I don't think it would corrode. You can test. Get a piece of steel and leave it wet and make sure it rusts. Then clean it off and then stick it in a container of crushed ice and stick the whole thing in the freezer. $\endgroup$

  • $\begingroup$ Water is oxygenated. Should theoretically be possible to rust it. Though it'll be slower than liquid water. If I were to select a coating, I'd try a thin layer of epoxy. $\endgroup$
