This is an interesting tale. What is missing is how the problem was solved. I have seen corrosion pop up on machined parts and not had an explanation of how to prevent it from anybody in the shop. Of course, these parts were steel, not stainless, and they were black conversion coating treated. The eventual solution, which met with a lot of complaints, was to boil the parts for a few hours in clean water, with a new batch of water every hour. It seemes that some of the blackening solution had remained in some of the small tapped holes in the fixture, and was responsible for the corrosion.
For the problem with the stainless parts in the story, one fix would be to change to a non-free-machining grade and grind the parts to size. Not a cheap or easy fix, but probably quite effective.

Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
