A little metal fatigue, maybe?
In metallurgy fatigue failure is the result of repeated loads that exceed a certain load. Fatigue failures are most commonly associated with rorating machinery. Fatigue is fairly complicated but generally involves stress raisers, such as sharp corners, and the nucleation and growth of dislocation clusters. WikiPedia has an article under Fatigue (material).

That nut must have been grown in iron rich soil because it looks like it's stronger than steel! Lucky the cracker broke; just what it would have done to your teeth.

Chinese quality
Just more cheap China pig iron! Nickel pig iron (NPI) is a low grade ferronickel invented in China as a cheaper alternative to pure nickel for the production of stainless steel.

That picture says it all. The Chinese fasteners - screws, etc. are the absolute worst. Thanks for all the posts... all good chuckles.

Nickel pig iron as a final use metal is virtually useless, but as an alloying feedstock in open hearth furnace stainless steel making it would be valuable. But stainless is not generally open hearth produced as the quantities are too low. I would gather most stainless steels are made in the smaller electric arc furnaces.
