Ok, I did a few trial runs of washing the parts in DI water afrer the machining operations and found that it greatly reduced, but did not completly eliminate, the corrosion issue. With the DI water, there was no flash rust but after a few hours a few small spots of rust could be seen. I have...
We do not mix our cutting fluids but we do use city water for washing the parts after each manufacturing operation. We have one sink that is DI water, I will do some testing with that to see if it makes a difference.
"We did it once and it worked" is one of my main concerns...I have done some research and did not find anyone else that was cleaning tool steel in this manor and wondered if there was a reason for that. I planned on keeping the methanol in sealed containers as EDStainless mentioned and possibly...
Flammability won’t be an issue. These parts are not exposed to any heat or spark and they go through a final cleaning operation before they are sent to the customer. It is just when the parts sit in process that the problem occurs.
Currently, a heavy duty degreaser/soap and hot water is...
The parts usually rust in about 30-45 minutes so I assume that would be flash rust...thanks for the lead, I will look into that product. I have tried other corrosion inhibitors with no success but I'm willing to try another.
Now that still doesn't answer my question about the methanol...
I am currently having corrosion issues with M42 tool steel parts that I am manufacturing. As a temporary fix, I have been placing the parts in WD-40 during any time the parts are not being machined. I would like to get away from the oil due to the messiness, it is difficult to dispose, and is...
