    Tool steel and methanol

    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...

    Tool steel and methanol

    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.

    Tool steel and 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...
