“compromised steel from China”
One time we were machining a piece of steel from an unknown source in China. You could clearly make out the outline of a wrench when we cut it open. On another was the impression of a bicycle sprocket. That was the shittiest steel I ever saw. Someone got taken to the cleaners on that deal.
About 25yrs ago Mexico melted down a bunch of X-ray machines complete with the source still inside. It was made into rebar and rod that was used to make patio furniture.
It was so hot it supposedly would render you sterile in minutes. If it weren’t for a load of rebar that set off radiation detectors when it entered the Nevada Test Site, it might have never been discovered.
