Not only were the rivets below standard, but the steel used in the hull was not strong enough for that large a ship. When the first pieces of broken hull steel were brought up and analyzed, it was noted that the steel was brittle. At first it was thought that the immersion in sea water had weakened the steel, but a bloke in Canada has a rivet hole punching from the hull. It was kept as a paperweight by his grandfather who worked on the Titanic as it was being built and had been handed down to the Canuk. Spectrographic analysis showed that the hole punching and the fragment of the hull were the identical alloy. From this it was determined that the ship builder engineers had built faster than the current metallurgy capability. There was a fragment of the hull about the size of a dinner plate brought up and it was ragged along its edges. To me it appeared to have been so hard that it shattered instead of bending as one would expect. Jesse, the crazed machinist in Troy, TN MODEL ENGINEERING DISCUSSION LIST.
