I don't care if you think I am rude or not, but I am right.
>Pls provide proof (and not some lab experiment or some yahoo eating
2/3rd the way through metal with abrasives) that these things are actual
concerns.
Or is this list full of old wives and thier old wives tales :)
Huh????? Are gonna tell us next that the world is flat, and that the Appolo missions were filmed in the desert, and that Elvis lives?
It has been a number of years since I sat in a college classroom a studied work hardening, cold working and nitrogen embrittlement...but all of these things are very real, and have been of concern to engineers for ages. However, since you seem to think engineers know nothing, perhaps you should check with an old-time blacksmith who does not have a college education. He can verify this.
In the meantime, I'm glad you have yet to suffer any ill effects from your "it hasn't happened to me so it can't be true attitude."
Regards,
David Doyle
