I have an old structural engineering book, published about 2 years after the
sinking. The problem caused by too much sulphur was well known at the time.
It's a UK textbook, "Theory of Structures".

I'm going to quote a portion of a post from a chap named Roger Long on
rec.boats cruising. I will not quote the entire post as you can
contact him on that group if you are interested.

Yes, the rivet lady. Cute gal. 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.

He may have a point, but he isn't real keen on metalurgy...

You may be right.
The guy makes his living designing survey boats and other ocean going
vessels, for various research organizations like Woods Hole, etc.

The problems caused by sulphur and phosphorus were known before the
1700's, although they didn't understand the chemistry.
