Are you the hulk?
[QUOTE
Bars have to endure a lot force with an ''agressive" riding position. I only trust steel with this force The idea of carbon or alu bars snapping while riding makes me fear them a lot. I trust alu more than carbon but alu can so get fatigued. Steel will not snap.[/QUOTE]
Yeah...I dunno about that
Nitto (& probably other) heat treated alloy bars are pretty strong
not trying to say steel isn't real....nice.

When I was a teenager I had a handlebar snap off while sprinting It broke off near the stem.
It was in I imagine maybe 1979 or so
It was an aluminum heat treated Sakae handlebar that I bought at a bike shop to put on my ten speed.
Somehow I managed not to fall and kept going holding the stub so that it wouldn't foul the front wheel.
Ever since then, I've been so suspicious of all handlebars. It was then that I learned about stress risers. Anything that clamps on the bar, like brakes, must not be over tightened.
Back then most bikes had quill stems and one single pinch bolt.
I'm also leery of having bikes fall down - tip over. In my imagination I think a carbon bar could get damaged this way, and you wouldn't ever know it. Chances are very low though and shouldn't be worth worrying about.
Steel would shrug off being tipped over hard.
But I'm no expert. This is how it looks to me.
Steel is heavy though. Not all steel is the same. There are crappy things that bend! I've ridden that department store stuff back in the day ( but they wouldn't snap).
Stems also give me the creeps sometimes when I look at them. They can look anemic when I consider what's at stake and the forces involved. But I haven't heard of these breaking. Have you?
Still, I'm particular about the stem. Oh yeah, there were some Thomson stems that broke and people were hurt. Some stem clamps have 4 bolts, 2 bolts, and some are even hinged. They come in all materials as well.
I wished to build my steel single speed commuter out of all steel parts, but didn't. Steel stem, seat post, didn't materialize because I couldn't justify spending more money where the parts I already had were lighter and trustworthy.
WHat I strive for in this regard, is confidence in the equipment. It is a psychological dilemma , emotional and therefore prone to irrational unobjective interpretation.
That is to say for example that someone without good instruction might overtighten clamps thinking it is more secure to do so.
There is science, and that is a better guide than superstition.

No I've never had steel cranks yet.
Forged aluminum are proven. I had a pair of CNC aluminum billet cranks that failed on the non drive side.
Had chainring failure. The other weekend I had an 11 speed SRAM chain break. I think, usually something else will give before the crank does. But I've seen photos of it happening.
With cranks a common failure is for them to come of the spindle I'm various ways. That's happened to me with the Octalink type.
