As multiple posters have already pointed out, you have no idea how jet engines are made. Lets make it simple. No, it had nothing to do with Chinese steel. But if it makes you sleep well to think that, then go for it.
There was a case of two pilots shutting down circuit breakers on their jet, a National Airlines DC-10 on a flight to California which caused an engine to shred itself, like this one. The engine also shot shrapnel into the cabin, breaking a window, from which a male passenger was pulled out. His body was never found. http://www.planecrashinfo.com/unusual.htm It happened Nov. 3rd, 1973, a day before my 6th birthday. :-)
