Did bad rivets cause sinking of Titanic
The article does not amount to proof, but it is interesting. Another
one mentioned that if quality welding was available and used to make the hull, then it would not open up the way it did due to the collision. http://www.nytimes.com/2008/04/15/sc...15titanic.html |

Did bad rivets cause sinking of Titanic
Thanks for the post. I was one of the donors of period wrought iron
for the comparison testing. They (NIST)told me at the time that they'd keep me informed but I never heard from them.

Did bad rivets cause sinking of Titanic
This doesn't fit the scenario for wrought iron at all. Cast iron is
brittle for other reasons. The lower the carbon content, the less brittle and work hardenable the material. Pete Stanaitis ------------------------------ Gary Owens wrote: Figure it out for yourself. Get an old cast iron window weight, turn it down to about .75, cool it down to about 20 deg F , put it in a vice and whack it. Tell us what happens.

Did bad rivets cause sinking of Titanic
I provided a sample of double refined wrought iron that came from bridge
spikes that were recovered from the Mississippi River where most of that bridge ended up after being dynamited to get rid of it. A guy up here "mined" these spikes from the head end of an island and tried to sell them as historical artifacts, but nobody was buying, so I bought several hundred pounds of them at about 8 cents a pound, 20 years ago. FWIW, these spikes are 3/4" square and vary from about 2 feet long to about 3 feet long. Most of them, as I receive them, are bent in "S", "U" and other shapes, for obvious reasons. They tell me that the bridge was made mostly from 12" square pine timbers. I never heard of this "best" and "best, best" rating. All I know is: Muck bar (right out of the bloomery) Double refined Triple refined Used (This is usually considered better than muck bar, since it has been worked more). For blacksmiths, this wrought iron, being VERY low in carbon content can be worked a high heat. It is soft and doesn't work harden. I am glad that none of MY early riveting was holding the Titanic together.

First test was fine, sample bent a small, but measurable amount. The cold test, however, caused the piece to break like glass and bounce off the wall. They said the iron had a high sulfur content, that makes it VERY brittle when cold. This was with an actual sample of the Titanic plate brought up from the bottom. I think it was a Nova episode.

I think there also was a National Geographic article about the same time. Jon |

Did bad rivets cause sinking of Titanic
"Robert Swinney" wrote:
Purely and simply, the Titanic sank because it rammed an iceberg at nearly full speed. The strength of plates, of rivets, formulation of the metal in the plates; all had very little to do with it. Take any modern vessel and ram an iceberg at full speed and it will sink also. The "improved" strength of modern materials might only account for a few minutes difference in sink time. The reason Titanic sank was because the segregated internal compartments were not tall enough, and were open at the top. As the areas near the fracture filled with water, they pulled the vessel down, allowing the adjacent compartments to also fill with water from the top down (like an overfilled bathtub). This progressed until the boat sank. It the internal compartments had been taller, the cascading effect would not have occurred, and while the vessel would have still been crippled, it would not have sank. Jon |

Unfortunately, we were still working out the manufacturing processes for steel at the time. http://dwb.unl.edu/Teacher/NSF/C10/C.../aa022800a.htm It was the best there was at the time, but there were some unforeseen limitations. The process left it with Phosphorus levels 4 times modern levels and sulfur twice as high. Paul K. Dickman |

It the internal compartments had been taller, the cascading effect would not have occurred, and while the vessel would have still been crippled, it would not have sank. It appears that if the Titanic has actually "rammed" the iceberg (hit it dead on with the bow.) - the forward areas would have flooded, but the ship would not have sunk. What seems to have doomed the Titanic was not ramming the iceberg, but "side swiping" it - hitting the iceberg with the side of the ship, and thus, opening more compartments to the sea. The properties of the rivets and hull plates seem to have compounded the problem. So if that lookout had been slacking off, and slower on picking up the iceberg, and warning the bridge, everything might have been better off. tschus pyotr -- pyotr filipivich "I had just been through hell and must have looked like death warmed over walking into the saloon, because when I asked the bartender whether they served zombies he said, ‘Sure, what'll you have?'" from I Hear America Swinging by Peter DeVries |

Bob (doesn't quibble over a few k-pounds) Swinney I think the ability of seawater to cascade from one compartment to the other had something to do with it, too, IIRC. Had the compartments been truly watertight, only a few of them would have flooded, and the ship could have stayed afloat with the buoyancy of the rest. DO NOT quote me on this. Steve |

Steve All steel plate. Casting ship plate wouldn't make sense. The steel, as other have mentioned, had the property of cold-shortness, caused by too much sulfer and phosphorus. The common 12L14 leaded freecutting steel we love to machine has the same problem. Machinability has its drawbacks. Dan |

Did bad rivets cause sinking of Titanic
On Tue, 15 Apr 2008 22:57:21 -0500, with neither quill nor qualm,
Ignoramus15568 quickly quoth: Check this out http://intheboatshed.net/wp-content/.../titanic_8.jpg What is in the middle, covered by a bench side? Looks like a disposable plastic cup to me. Yeah, a beer cup from the stadium. Hmmm... Did anyone ask Kate or Leo if it was theirs? -- It is better to wear out than to rust out. -- Bishop Richard Cumberland |

The cold test, however, caused the piece to break like glass and bounce off the wall. *They said the iron had a high sulfur content, that makes it VERY brittle when cold. * Jon The Ken Marschall painting of the port side of the stern "based on photographs taken of the wreck" shows bent and wrinkled lower side plating with some rips that cross plate edges. I think I remember seeing a painting of the other side with the plates separated along the seams. Maybe that was another shipwreck? Jim Wilkins |

My "toy box" contains a small handful of crushed coal recovered from the Titanic. I purchased it from Ballard's group about ten years ago. Why? I dunno... Probably the same unknown reason why I bought a small piece of the Berlin wall when it came down... I can rationalize those purchases by saying that if I'd spent the same money on booze it'd have dissapeared down the drain long ago.

I was really looking forward to being flown out to Seattle to be filmed with her as part of the show but she wouldn't even answer our phone calls. They kind of overlook some basic engineering and structural facts. With a structure as heavy and delicate as the Titanic, and even a modern welded ship would be considered delicate in these terms, and something as immovable as a iceberg entrained in the water mass, the damage path was going to be determined by the geometry of the encounter.

Did bad rivets cause sinking of Titanic
This is an interesting book on steel technology in 1921 by Fred
Colvin; http://www.gutenberg.org/files/20282...-h/20282-h.htm "Sulphur is of most trouble to rolling and forging operations when conducted at a red heat. It makes steel tender and brittle at that temperature—a condition known to the workmen as "red-short." It seems to have little or no effect upon the physical properties of cold steel— at least as revealed by the ordinary testing machines—consequently many specifications do not set any limit on sulphur, resting on the idea that if sulphur is low enough not to cause trouble to the manufacturer during rolling, it will not cause the user any trouble.
