This is why titanium sucks.

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

This is why titanium sucks.

Steel is real....this don't rhyme, for no reason. No more ti bolts for me. They are simply less than just one use items!

I actually had a wheel stud on a car break, and then all four of the remaining studs shear off causing me to lose a front wheel around a gentle curve at 60mph.

Ti works great for frames and some parts but not for bolts, they work, sorta ok, on things you can pre-torque with a steel bolt - such as crank arm bolts

Ti galls and jams easily especially on Ti to Ti, Or Ti to Aluminum. It must have anti seize or Teflon tape on the threads. A small amount, but on all the threads. Don't skip any threads. To spread it evenly you might want to tread it in once and then remove it. Then wipe off any material to keep the mess at a minimum.
Do it right you will have no problems. Copper or Nickle base Anti seize will do the job on ti. The difference between nickel and copper base
anti seize is high temperature resistance, it has nothing to do with materials. Teflon plumbers tape works just as well and is cheap. I have spent a lot of time researching this and testing it. Even Litespeed did not know the nickel vs. copper use of anti seize. All ya gotta do is read.

In fact you should use it on ti to steel too. It's cheap. Yes the Ti bolts can be broken anyway, they are not as strong as some others.

use a left handed drill bit from the outside. usually once the bit bites a little it will spin the bolt out. if not a really small easy out to finish it.

Used a torque key?

A lot of experience does not a good mechanic make.

Use Ti prep - the copper colored stuff only on any Ti threaded items. Always always always...

Pro tip: If a component is marked for a max torque of 5Nm, don't use a 5Nm torque key of unknown tolerance or calibration to fasten it.

First Ti doesn't suck. ..even for bolt applications. So OP, your comment about this being a public service to avoid Ti stem bolts is ill founded.
I have used Ti stem bolts for years. Let's say you did everything properly. What 'may' suck is the grade or material properties of the bolts that 3T uses to minimize cost. I have never had an issue with Ritchey Ti bolts.
Popular materials or alloys don't by and large suck. What sucks is lack of attention to mfg. tolerances which includes spec's on material properties.
3T may cut a few corners...or this is just an outliar which also occur with all mfr's.
So OP, your thread title sucks more than Ti. Lastly, far and away the biggest group of failures is due to 'operator error' when it comes to bike set up.
Not saying however this is the case here.

Let me rephrase your thread title:
Ti is great material...but

This.
Snapping at 5nm....no other explanation that I can think of other than opperator error....and I think the OP showed due dilligence using a torque key. even if the torque was off a bit, one has to think it would be within the margin of safety.

I think the issue is: who makes them? What grade? Is there even a grading system? Are they made from scavenged Chernobyl cooling pipes?...the innerds of a Soviet sub that has been sitting on the bottom of the Baltic for 30 years?
Ti bolts cost (comparitively) big bucks, they're blingy and attract cyclists like free Pabst and skinny jeasn attract hipsters. You don't think that there will be a large number of less than scrupulous characters trying to cash in?
Think: Melamine in dog food.

Were the threads rolled on or cut into the offending Ti bolt. I think it makes a difference as rolled on threads are less likely to produce stress risers that quickly develops into cracks. Cheaper/lower quality fastenenrs usually have cut threads. I suspect we get badly made Ti bolts once in a while with components, specailly if they were sourced from the far east.

Excellent point.

Must be pretty hard dies to roll a thread onto Ti. Or not long lasting?

The stem is specced for a MAXIMUM torque of 5Nm and that's way more than necessary for secure fastening. Using a torque key rated for 5Nm is operator error. Period.

he took over and subsequently split his seatpost in half

Titanium doesn't suck. That particular bolt you used does.
